Technical data for special compressors see BITZER software andappropriate documentation.

Explanations

➀ CR Capacity control (option) 220 .. 240 V/1/50/60 Hz

➁ Tolerance (±10%) based on mean value of voltage range.Other voltages and electrical supplies upon request.

➂ Data refer to 400 V/3/50 Hz at direct mains operation.For the selection of contactors, cables and fuses the max.operating current / max. power consumption must be considered. See also ➄.Contactors: operational category AC3.Use thermal overload relay to limit max. operating current.

➃ PW: motor for Part Winding start Y/YY• 4VES-6Y .. 6FE-50(Y)

winding partition 50%/50%• 8GE-50(Y) .. 8FE-70(Y) /

winding partition 60%/40%• For Part Winding start select motor contactors

for approx. 60% of the max. operating current.Y/ version upon request

➄ Data for frequency inverter (FI) selection – motor version 3(R134a compressors):based on 400 V/3/50 Hz supply voltage and use of 400V/3/50 Hz standard motor for FI operation up to 70 Hz.FI with motor version 1 and 2:operation in the entire application range above 50 Hz requires motor with special voltage.Selection upon request.

2.6 Compressors data for previous models

Comments

In the following chapter the technical data of the pre-vious models (Octagon and .2-Generation) is shown.

Since the models of the NEW ECOLINE series havebeen only slightly changed, only the technical data of the previous models is shown. The drawings arealmost identical to the corresponding types of the NEW ECOLINE series (see comparative table on pages106-108).

There are some dimensional changes in the shut-off valves for BE5 & BE6 series compared to previousmodels. All other dimensions remain unchanged.Dimensional drawings of the previous models see theBITZER Software.

3.2 Motor codes

Motor code for semi-hermetic reciprocating compressors

In consideration of the various power supply systemsBITZER offers motors with different operating voltagesand frequencies for all semi-hermetic reciprocatingcompressors.In the following tables the available operating voltagesfor the specific compressor groups are listed. To iden-tify the operating voltages and the motor connection,BITZER adds the motor code to the compressor name.

Example:4CC-6.2Y-40S

Compressor typeIndication for nominal voltage: 400 V / 50 HzMotor connection: S = Star wiringD = Delta wiringP = Part windingN = Dual voltageE = Single phaseU = UL approval

For motor code 40S the table on page 138 - 140 showsthe different motor connections for the respective ope-rating voltages and frequencies:

Function

Compressor start

The oil pressure monitoring is activated when supplyvoltage is applied via an auxiliary contact of the motorcontactor K1 (operating recognition, see also schematicwiring diagram). The LED at the front end of the elec-tronic unit immediately signals an insufficient differen-tial oil pressure.

Operation

Once the preset value has been reached, this LEDextinguishes. The output contact remains closed if thedifferential oil pressure reaches or exceeds the presetvalue.

Differential oil pressure below preset value

If the differential oil pressure remains or drops belowthe preset value for longer than the time delay (approx.90 s), the output contact opens. The Delta-PII locks outand shuts off the compressor. The signal lamp H2 andthe LED at the protection device both stay on untilDelta-PII has been reset.

Shorter times of insufficient oil pressure are also recog-nised by the internal microprocessor. They also lead to

a compressor shut-off after a correspondingly extend-ed time delay (time integration).

Manual reset

Interrupt power supply (L/N) for at least 5 seconds (resetbutton S3, see schematic wiring diagram, page 147).

Fault of Delta-PII

In case the supply voltage is too low or if the electronicunit is not completely mounted, the Delta-PII locks out.The LED at at the front end of the electronic unit isflashing.

LED indications

• LED is on:lack of oilThe signal lamp H2 is also on.

• LED is flashing:fault of Delta-PII

• LED is off:sufficient oil supply


Connect Delta-PII according to schematic wiring dia-gram. Mount reset buttons S2 and S3 into switchboard.The following schematic wiring diagram applies to partwinding start. For direct start K2, K1T and Y1 can beomitted.

4.2 Crankcase heater

General

During the shut-off periods a high amount of refrigerantcan be dissolved in the crankcase oil depending onsystem type and refrigerant charge. The consequencesare increased oil carry over, liquid slugging andreduced lubricity during the next start. In critical casesthe compressor might fail.

The operation of a crankcase heater keeps the dilutionof the refrigerant down on a level which gives no causefor concern in most cases.

The heating is particularly important under the followingconditions:

• in case the oil temperature (crankcase) drops to avalue which is less than 15 .. 20 K above the tempe-rature of the evaporator (saturation temperature) – e. g. during longer shut-off periods.

• in case of temperatures of less than 10°C at thelocation of the compressor.

4.3 Start unloading & capacity control

Start unloading for BlTZER reciprocating compressors

Types:• 4VES-6(Y) .. 66FE-100(Y)• 4FC-3.2(Y) .. 66F-100.2(Y)• 2T.2(Y) .. 6F.2(Y)• W2TA .. W6FA

Function

The start unloader basically consists of a by-passdevice which is controlled by a solenoid valve.

For part winding and star-delta start this solenoid valveis connected with the first part winding contactor orthe star contactor respectively. It is open for a shorttime during the starting phase (part winding 0.5 s, star-delta 1 .. 2 s). So an equalization occurs for a shorttime between the high and low pressure sides: Thecompressor starts unloaded. A check valve has to bebuilt into the discharge gas line. This prevents that dis-charge gas flows back from the condenser during thepressure equalization.

Unloaded start

The solenoid coil (1) is energized. With the aid of aservo valve the control piston (2) is raised and thebypass port is opened. The gas passes directly fromthe discharge gas to the suction gas chamber.

Normal operation

At normal operation the solenoid coil is de-energized.The by-pass port in the cylinder head is closed.

Check valve in discharge gas line

For operation with start unloading a check valve (6) isrequired in the discharge gas line. It prevents the dis-charge gas to flow back from the condenser andshould be selected according to the individual operat-ing conditions.

Discharge gas temperature sensor

Thermical protection of the compressor against possi-ble malfunction of the start unloading and / or againstexceeding of the thermal application limit.

8GE-50(Y) .. 8FE-70(Y) // 8GC-50.2(Y) .. 8FC-70.2(Y)

Even in part winding start mode a very high torque isachieved by the special motor winding configuration.Therefore start unloading is not required with thesecompressors.

Control principle

The CRII system for capacity control based on theprinciple of blocked suction. Hereby the suction-sidegas flow to the individual cylinder bank is blocked bymeans of a control piston (see fig.).

Full-load operation

In full-load operation the compressor delivers on allcylinders. The solenoid coil (1) is de-energized. The gasports in the valve plate and cylinder head are opened.

Part-load operation

In part-load operation the refrigerant gas flow of theswitched off cylinder bank is blocked. The solenoid coil(1) is energized, the suction port in the correspondingcylinder head is shut off by means of a control piston.

Application limits with part-load operation

The CRII system is capable of regulating the capacityof a completely equipped compressor virtually steplessbetween 100% and 10% of residual capacity. Tandemcompressors can be regulated down to 5% of the residual capacity.

The following application limits represent the residualcapacities 66%, 50%, 33% and 10%. Any optionaloperating point can be checked using the BITZER Software.

During CRII operation thermal load of the compressorrises due to:• reduced refrigerant mass flow,• reduced motor cooling and• electrical and mechanical losses.

Therefore the application ranges of the capacity controlled compressors are restricted to some extent.

Application limits

• always refer to the nominal voltage of the compressor,

• are also valid for the corresponding tandem comressor.

• Application limits for 8GE-50(Y) and 8FE-70(Y) upon request.Minimum residual capacity 50%(max. two CRII capacity contollers)

For application limits (diagrams) see KT-101

Additional cooling with part-load operation

To ways of additional cooling are possible(application ranges see application limits):

Additional fan

Additional fans are available for all compressor typesupon request. Mounting positions, dimensions andtechnical data see KT-140.

The compressor might also be located in the condenserair flow. For a cooling effect equal to additional fan theair velocity must be at least 3 m/s.

Air-cooled units

The unit fans can be equipped with a speed contoller.The air flow must be controlled in such a way that asufficient cooling of the compressor is always guaran-teed.

Subsequent mounting

The capacity control can be retrofitted on 4FES-3(Y) to8FE-70(Y) as a complete kit. Arrangement see KT-101,chapter 3, fig. 4.

The previous compressors (4FC-3.2 to 8FC-70.2) canalso be equipped with this system on the cylinder banksintended for this purpose (refer to KT-101).

Fitting of a capacity control may require additional cooling of the compressor.

The standard cylinder head must be replaced by a CRIIcylinder head. It can only be retrofitted as a completekit.

Warning!Compressor is under pressure! In case of inproperhandling severe injuries are possible.Release the pressure in the compressor!Wear safety goggles!

• Remove the screws from the cylinder head.• Dismantle cylinder head and seal.

Check the sealing surface on valve plate and clean it if necessary.

• Install a new seal and CRII cylinder head. Use the new screws and tighten them crosswise.Screw tightening torques:80 Nm for each screw.

Function of capacity regulator

The BITZER capacity control is based on the principleof suction shut-off. Hereby the suction-side gas flow tothe individual cylinder bank is shut off by means of acontrol piston.

Full-load operation

In full-load operation the compressor delivers on allcylinders. The solenoid coil (1) is de-energized. The gasports in the valve plate and cylinder head are opened.

Part-load operation

In part-load operation the pistons of the switched-offcylinder bank run idle without gas pressure. The solenoidcoil (1) is energized, the suction port in the correspondingcylinder head is shut off by means of a servo valve.

Application limits with part-load operation

Semi-hermetic compressors

With capacity regulator operation the temperature levelrises due to:• reduced refrigerant mass flow,• reduced motor cooling and• electrical and mechanical losses.

Therefore the application ranges of the capacity controlled compressors are restricted to some extent.

Application limits

• always refer to the nominal voltage of the compressor,

• are also valid for the corresponding tandem comressor.

• For 8GC-50.2(Y) and 8FC-70.2(Y) upon request.Capacity steps: 100 – 75 – 50%(max. two capacity regulators)

Application limits see KT-100

4.6 Additional cooling

General

It may be necessary to provide supplementary coolingfor the compressor when subjected to high thermalload (refer to application limits in brochures and BITZER Software).

Additional fan

This cooling method can be used universally. It offers auniform cooling effect and its performance can bemonitored easily (by means of electrical protection). Thefan is usually electrically connected in parallel to thecompressor. If the compressor is located in the airstream of the condenser fan (at least 3 m/s), it is notnecessary to install an auxiliary fan.

NH3 compressors require water cooled cylinderheads for additional cooling (standard version,additional fan can only be used under restrictionand after consultation with BITZER).

Mounting the fan

Dimensions and mounting positions seeTechnical Information KT-140.

Cooling water temperature

• Inlet:The cooling water for the cylinder heads should prefer-ably be supplied from the already warmed up coolingwater of the condenser.

• Outlet:The cooling water temperature must not exceed50°C. Adequate heat transfer is normally achievedwhen the inlet / outlet water temperature differenceis between 5 and 10 K or with a water volume fIowof approx. 150 l/h.

Compressor standstill

When the compressor is off, the cooling water supplyto the cylinder heads must be interrupted (e. g. waterregulator, solenoid valve) to avoid condensation ofrefrigerant back into the cylinder head.

Flexible pipe elements

If the compressor is flexibly mounted, the use of flexiblepipe elements is recommended (see page 228).

5.2 The temperature glide

General characteristics of zeotropic blends

As opposed to azeotropic blends (e.g. R502, R507A),which behave as single substance refrigerants withregard to evaporation and condensing processes, thephase change with zeotropic fluids occurs in a "gli-ding" form over a certain range of temperature.

This "temperature glide" can be more or less pronoun-ced, it is mainly dependent upon the boiling points andthe percentage proportions of the individual compo-nents. Certain supplementary definitions are also beingused, depending on the effective values, such as "near-azeotrope" or "semi-azeotrope" for less than 1 K glide.

This means in practice already a small increase in tem-perature in the evaporation phase and a reduction during condensing. In other words, based on a certainpressure the resulting saturation temperatures differ inthe liquid and vapour phases (see page 223).

To enable a comparison with single substance refriger-ants, the evaporating and condensing temperatureshave been mostly defined as mean values. As a conse-quence the measured subcooling and superheatingconditions (based on mean values) are unreal. Theeffective result – related to dew and bubble tempera-ture – is less in each case.

A-222-1

A_222_1_223-250.qxp 22.11.2013 12:16 Uhr Seite 232

These factors are very important when assessing theminimum superheat at the compressor inlet (usually 5to 7 K) and the quality of the refrigerant after the liquid receiver.

234 www.bitzer.de


With regard to a uniform and easily comprehensibledefinition of the rated compressor capacity, the revisedstandards EN12900 and ARI540 are applied. Evaporat-ing and condensing temperatures refer to saturatedconditions (dew points).

• Evaporating temperature according to point A (see page 233).

• Condensing temperature according to point B (see page 233).

Also in this case the assessment of the effective super-heating and subcooling temperatures will be simplified.

It must however be considered that the actual refriger-ation capacity of the system can be higher than therated compressor capacity. This is partly due to aneffectively lower temperature at the evaporator inlet.

Further conditions/recommendations concerning thepractical handling of blends must also be considered:

• The plant always has to be charged with liquid refri-gerant. When vapour is taken from the chargingcylinder shifts in concentrations may occur.

• Since all blends contain at least one flammablecomponent, the entry of air into the system must beavoided. A critical shift of the ignition point canoccur under high pressure and evacuating when ahigh proportion of air is present.

A-222-1

A_222_1_223-250.qxp 22.11.2013 12:16 Uhr Seite 234

235www.bitzer.de


• The use of blends with a significant temperatureglide is not recommended for plants with floodedevaporators. A large concentration shift is to beexpected in this type of evaporator, and as a resultalso in the circulating refrigerant mass flow.

Compressor installation

Place of installation

Install the compressor horizontally.

For operation under extreme conditions (e. g. aggres-sive or corrosive atmospheres, low ambient tempera-tures etc.) suitable measures must be taken. Consulta-tion with BITZER is recommended.

Anti-vibration mountings

The compressor can be rigidly mounted, if no dangerof breakage due to vibration exists in the associatedpipeline system. For compressors 2KES-05(Y) .. 4CES-9(Y) put a washer between each compressorfoot and frame (part No. 313 095-01).

Otherwise the compressor must be fixed on anti-vibra-tion mountings (page 239). This is particulary requiredwith mounting on shell and tube heat exchangers:

Attention!Do not mount the compressor solidly onto theheat exchanger.Damage of the heat exchanger is possible (vibration fractures).

Mounting of discharge line and suction line:• Mount compressors either flexible on damper

elements or rigid. In this position (operating mode)suction and discharge tubes must be connectedstress-free.

6.3 Special recommendations for safe compressorand plant operation

Analyses show that the vast majority of compressorfailures occur due to inadmissible operating conditions.This is especially true for failures deriving from lack oflubrication:

• Expansion valve operation – pay attention to themanufacturer’s guidelines!– Correct position and fixation of the temperature

bulb at the suction line. When using a heatexchanger, place bulb behind evaporator, as usual – in no case behind the internal heat exchanger if there is one.

– Sufficient superheat.– Stable operation at all operating and load condi-

tions (also part load, summer / winter operation).– Bubble-free refrigerant at expansion valve.

• Avoid refrigerant migration (high pressure to lowpressure side) during longer shut-off periods.– Application of a crankcase heater.– Pump down system (especially if evaporator can

get warmer than suction line or compressor).– Automatic sequence change for systems with

multiple refrigerant circuits.

Use of a liquid / suction line heat exchanger canhave a positive effect on efficiency and compres-sor operation with HFC refrigerants having a lowisentropic exponant (R134a, R404A, R507A).Place expansion valve bulb as described above.

6.4 Vibrations

Vibrations on the high pressure side

Vibrations on the high pressure side of refrigeration systems are mainly caused by:

• Pulsations• Structure-borne vibrations• Frame design / basement

Pulsations

Pulsations (longitidunal gas vibrations on the high pres-sure side) are created by the discharge process of thegas out of the cylinders. Their amplitude and frequencydepend on:

• Compressor speed• Number of cylinders• Cylinder alignment• Refrigerant properties (Pressure, temperature and

sonic speed)

Critical discharge gas vibrations can be found if the fre-quency of the oscillating gas column in a straight disch-arge tube section gets into resonance with the naturalfrequency of the pipework. In the worst case this couldresult in a fracture of the piping.The length of the pipe segment with a resonance fre-quency corresponding to the natural frequency of thegas flow is designated as "critical pipe length".

Calculation of the critical pipe length for our com-pressors is possible upon request after submittalof refrigerant and the operating conditions.

Influence of the refrigerant on the pulsation behavior

The pulsation behavior depends to a great extend on therefrigerant properties (gas forces, pressure levels, sonicspeed). Especially in retrofit cases the pulsation effectsof different refrigerants can become apparent. Forinstance R404A / R507A shows a significantly highertendency for discharge gas pulsations in comparison toR22 due to the higher pressure levels, higher gas densi-ties and lower sonic speed.The changeover from R22 to R134a is relatively uncom-plicated in terms of pulsation due to the low pressurelevels and density of R134a.

With the NEW ECOLINE series BITZER has introducedNew modified cylinder heads which contributed to a sig-nificant reduction of pulsation effects, especially withregard to R404A / R507A.

Structure-borne vibrations

Structure-borne vibrations are caused by unsteadyrotations and reaction forces at the compressor’smounting. Main cause are mass-forces of the com-pressor’s crank drive.

Frame design / basement

In general there are two methods for the installation ofsemi-hermetic reciprocating compressors to realize avibration optimized frame or base construction.

Soft installation (more common for single compressorsystems)

Compressors that are installed on soft damper systems(e.g. spring dampers) show deflection movementsduring the compressor start and shut-off. The softmounting leads to an effective dampening of thestructure-borne vibrations.Piping connected to the compressor, such as suctionand discharge line, but also measuring and controlpiping need to be flexible enough to compensate thecompressor deflections. This can be achieved e.g. bythe installation of vibration eliminators in the suctionand discharge lines. The framework or basement mustbe designed sufficiently rigid.

Rigid installation (more common for parallel systems)

Rigid mounting of several compressors on a commonbase frame involve the risk of the superposition ofnatural frequencies due to small speed differences of

A-222-1

A_222_1_223-250.qxp 22.11.2013 12:16 Uhr Seite 250

251www.bitzer.de


the compressor’s rotational speeds. The piping betweenthe parallel operated compressors (suction and dischar-ge header, oil and gas equalization lines) have to beinstalled rigid as well. The frame has to be built with asufficient bending stiffness. It also has to be separatedfrom the basement by pulsation dampening machinefeet.

Additional advices to prevent critical vibrations

1. For both mounting methods, rigid and soft, thepiping should be arranged in parallel to the compressoraxis and as close as possible to the compressor body.

2. With frequency inverter operation the vibrationissue multiplies. A pulsation optimised frame design isto be considered in order to avoid resonance effects. During commissioning the variable speed controlledcompressor should be manually operated through theentire speed range. Frequencies at which resonancesoccur must be faded out during frequency inverter pro-gramming.

Vibration velocity is an indicator for vibration fractures.The risk of pipe fractures due to excessive vibrationscan be estimated by the vibration velocity (in mm/s) andcan be measured with a special device if it ocurrs long-term.Measured values above 25 mm/s (steel pipes above 45 mm/s) have to be regarded as critical and may leadto pipe fracture.In general the vibration velocity is considered to be morecritical with increasing vibration frequency.

volumetric displacement decreases due to reverseexpansion from the pressure chamber into the workingchamber.

➁ Maximum evaporating temperature

If the compressor operates at an evaporating tempera-ture close to the maximum allowed evaporating tempe-rature the compressor delivers a high refrigerant massflow. Hence high forces develop on bearings and drivegear.

➂ Motor load

The motor load of a semi hermetic reciprocating com-pressor depends on the operating point. The higher theevaporating temperature and the higher the condensingtemperature, the higher the corresponding motor load.

➃ Maximum condensing temperature

The maximum condensing temperature is limited by thesaturated vapor pressure as well as the maximum allo-wable operating pressure on the high pressure side ofthe compressor. According to EN378-2 the maximumallowable operating pressure of systems with pressurerelief devices must not exceed 0.9 x maximum allowableoperating pressure.

A-222-1

260 www.bitzer.de


➄ Minimum evaporating temperature

With decreasing evaporating temperature the saturatedvapor pressure of the refrigerant decreases as well. Forsafe operation the circuit should not be operated atpressures too much below ambient air in order to avoidpenetration of ambient air into the suction side of thesystem through a leakage. At low evaporating temperatures the refrigerant massflow of the compressor as well as the suction gas den-sity are decreasing. This can possibly lead to an insuffi-cient motor cooling as the delivered refrigerant massflow is too low.

➅ Thermal limit

At low evaporating temperatures in combination withhigh condensing temperatures the thermal load limit ofthe compressor restricts the operation. There are vario-us possibilities to extend the application limits such aswater cooled cylinder heads, additional fans, restrictingthe allowable suction gas superheat or, in individualcases, a direct liquid injection into the suction side of thecompressor. The recommended methods for additionalcooling are displayed in the application limits diagram asicons
