Upflow and Downflow Versions Direct Expansion and Chilled Water Units

The “T” Range comprises nineteen (19) models, in six (6) cabinet sizes, with nominal capacities from 3 kW to 80 kW in the following versions: -

- X: Split System using Denco Condensing Units. - A: Air Cooled DX System with inbuilt compressor(s) and using Denco DCRA

Condensers. - W: Water Cooled DX System with inbuilt compressor(s) and Water Cooled

Condensers. - F: Ambicool System. - C: Chilled Water System.

Key to Type Codes Example: U 28 A V G H

H = Humidifier fitted G = Front Grille Return [Upflow only – not on U48 - U83]

(as opposed to underfloor return) V = Variable Refrigerant Flow (VRF)

A = X - Split System A - Air Cooled System W - Water Cooled System F - Ambicool System D - Combicool system C - Chilled Water System

28 = Unit Size: 3, 4, 5, 8, 10, 12, 17, 19, 21, 23, 28, 32, 37, 42 48, 53 63, 73 and 83 (models available dependent on System)

U = Upflow (D = Downflow)

Energy Saving Options GEA Close Control T-Range


“T” Range air conditioning units incorporate all of the energy/cost saving benefits for which Denco products are renowned. These include:

Ambicool (Glycol freecooling system) - "F" Version (not available on models 48 – 83) This substantially reduces annual energy consumption, and consequently costs, by exploiting low average ambient temperatures to provide partial or full freecooling. It is very unusual to experience the design summer ambient for any length of time, and external temperatures are generally considerably less for much of the year. This allows the drycooler to produce glycol at lower temperatures.

When the glycol is colder than the room air, it is passed through the economy coil before reaching the condenser, picking up some heat directly from the room rather than via the refrigeration system. Under conditions such as this, the compressor run time is reduced, thereby saving energy. As an example, some degree of freecooling is usually available for 70% of the year in northern Europe, giving very substantial running cost savings.

Variable Refrigerant Flow (VRF) - "V" Option This provides various compressor options for efficient part-load performance, with exceptional economy.

Full Cooling Load Both compressors running to circulate the full design refrigerant flow in order to achieve specified maximum cooling capacity. The scroll compressor coefficient of performance (COP) is typically 3.5.

Part Load Operation Lead compressor only running to circulate approximately 60% of the refrigerant flow. Evaporator and condenser are both oversized under this condition, causing increase in suction pressure and a reduction in discharge pressure. Resultant part-load COP increases to typically 5.0.

Secondary benefits include reduced temperature swing and increased compressor reliability caused by reduced cycling and an optional two-stage high-pressure trip. Lower inrush current and inbuilt redundancy is also provided by dual compressors and reduced humidifier run time – due to the very high sensible heat ratio achieved at the higher evaporating temperatures. Payback period is typically less than one year.

GEA Close Control Service Entry / Access T-Range


The “T” Range of air conditioning units has been designed to be completely front access for service/maintenance via the front hinged/removable doors. Therefore, no allowance for access to the ends or back is necessary, although the end panels can be removed in-situ if required.

Guide Specification GEA Close Control T-Range


Cabinet The cabinets shall be attractively designed having bevelled corners with flush fitting curved panels. Units shall have a rigid frame, manufactured from non corroding Aluzink, with hinged curved front panel(s) to provide access for installation and servicing. Panels shall be lined with class "O" non eroding insulation material with both thermal and acoustic properties. External panels shall be manufactured from pre-coated steel, colour Grey (RAL number 7024).

Cooling Coil The coils shall be multi row constructed from 3/8" O/D copper tubes with mechanically bonded aluminium fins. Direct expansion coils shall have internal grooving for optimum heat transfer. The coil face area shall be maximised to ensure high sensible heat ratio and low airside pressure drop, thereby minimising fan power and noise level. A stainless steel drain tray shall be included to ensure efficient removal of the condensate, via a factory fitted trap.

- DX: Units shall have one, two or four refrigeration circuits (dependent upon model), inclusive of liquid distributor, expansion valve, solenoid valve, sight glass and filter drier, and these components shall be housed in the cabinet.

- C: Units shall be fitted with a modulating 3 way valve having manual override facility with water pressure / temperature test points, and these components shall be housed in the cabinet.

Fans “T” Range models 3 to 5 shall be fitted with one fan, which shall be single inlet backward curved centrifugal, and shall be direct driven by an integral motor. A differential pressure switch shall be fitted to monitor airflow, failure of which shall result in an alarm and automatic disabling of all functions. The fan motor shall be single speed, the final airflow therefore depending on exact static pressure requirements.

“T” Range models 8 to 42 shall be fitted with one, two or three fans, whilst models 48 to 83 shall be fitted with four or six fans, depending on unit size. The fans shall be double inlet, double width with forward curved impeller, and shall be direct driven by an integral motor. A differential pressure switch (8-42) and current monitoring relay (48-83) shall be fitted to monitor airflow, failure of which shall result in an alarm and automatic disabling of all functions. Fan motors shall be three speed. HIGH or MEDIUM speed shall be factory selected, depending on airflow and static pressure requirement, and LOW speed shall be assigned for dehumidification mode.

GEA Close Control Guide Specification T-Range


Electric Heaters Electric heaters shall have rigid Incoloy sheathed elements with stainless steel finning balanced over three phases and rated to operate at black heat. Control shall be in one or two stages, each stage being protected by a high temperature safety cut-out.

Filtration The filters shall have an efficiency of 30 % ASHRAE 52/76 Eurovent 4/5 arrestance value 90 % (G4). They shall be fitted in the return air stream, held by quick release retaining clips, and be accessible from the front of the unit. A differential pressure switch shall be fitted which, through the alarm facility in the microprocessor controller, shall indicate when the filters need changing.

Water Cooled Condensers The condenser shall be a compact brazed plate heat exchanger having a multiplicity of parallel stainless steel pressed plates. The construction shall give high turbulent flows resulting in a compact heat exchanger form with low pressure drops.

Humidifier The humidifier shall be of the electrode boiler type, located in the bottom of the unit. Features shall include proportional steam output and microprocessor control with alarms and diagnostic facilities. The control system shall allow the use of a wide range of mains water conditions and optimise drain down frequency for maximum operational economy.

Compressor and Safety Controls Robust fully hermetic scroll compressor(s) shall be located either in the base of the unit on "A", "W" and "F" systems or the outdoor condensing unit on "X" systems. The compressor(s) shall be resiliently mounted on a robust frame, which assists to minimise noise and vibration transmission to the structure. The compressor(s) shall be fitted with back seating isolating valves together with crankcase heater ("X" systems only) and oil level sight glass on larger models. Protection shall be provided by an internal self-setting overload device and pressure relief valve.

GEA Close Control Ancillaries and Options T-Range


Plinth For upflow units, a standard plinth is available that raises the Air Handling Unit 200mm (or 400mm) from the floor level to facilitate services entry. It is a plain sheetmetal box supplied complete with gasket and fixing bolts, and finished to match the Air Handling Unit.

Base Stand When the Air Handling Unit is to be installed before the installation of a raised floor, a matching Base Stand should be used to support it. This consists of a rigid frame of 6mm thick MS angle complete with adjustable feet. The upper face of the frame is lined with 3mm semi hard gasket. When ordering, specify the nominal height required, which normally will be the same as the overall height of the raised floor. The feet have an adjustment of ± 25mm.

Ceiling Return Duct The Ceiling Return Duct is a rigid riveted sheetmetal assembly comprising of unit matched panels lined with 25mm thick insulation. The duct, which is suitable for downflow units only, is bolted to the top of the Air Handling Unit on site. When ordering, specify the height between the top of the Air Handling Unit and the under side of the suspended ceiling. The overall height of the duct will be this dimension plus 50mm.

Horizontal Discharge Section The Horizontal Discharge Section consists of a double deflection grille fitted into a rigid sheetmetal box. The complete assembly is bolted to the top of the Air Handling Unit on site. The grille has two sets of blades, which allow for both vertical and horizontal directional adjustment of airflow. The standard height for this section is 500 mm.

Ceiling Discharge Section For upflow units, where the Air Handling Unit is required to discharge into the ceiling void, a Ceiling Discharge Extension is available. This consists of a rigid riveted sheetmetal assembly comprising of unit matched front; rear and end panels lined with 25 mm thick insulation. The extension is bolted to the top of the Air Handling Unit on site. When ordering specify the height between the top of the Air Handling Unit and the underside of the suspended ceiling. The overall height of the duct will be this dimension plus 50 mm.

High Efficiency Filters Higher specification filtration can be provided in place of the standard filters having an efficiency of 80% ASHRAE 52/76 (Eurovent F7). Pre filters are fitted, before the main high efficiency filters, and are rated as G2. These filters are fitted in the return airside of the Air Handling Unit within the main cabinet.

Filter Gauge A dial type manometer can be installed to read the pressure drop across the filter to give an accurate indication of filter condition.

Ancillaries and Options GEA Close Control T-Range


Fresh Air Kit and Filter Units can be supplied with a fresh air inlet connection and disposable fresh air filter element. This will admit approximately 35 % of the recirculated air volume. One or two may be fitted depending on requirements.

Special Colours Special Colours must be specified when ordering the Air Handling Unit (quote British Standard number, RAL number, or other, if known). If more than one colour is specified then state the colour of each panel.

Double Skin Panels To reduce the sound "break out", Double Skin Panels comprise: - 20 swg steel sheet glued to the inner face of all outer panels then covered with standard 25mm class “O” insulation.

Without Electric Heating All equipment associated with electric heating is removed from the Air Handling Unit.

LPHW Heating (not available on models 48 – 83) Units may be fitted with a Low Pressure Hot Water heating coil in place of the standard electrical heating. Water flow through the coil is controlled by a modulating 3 way valve. Duties of these coils are nominally the same as standard electric heating, based on flow and return hot water temperatures of 82 °C and 71 °C respectively.

Water Detection Water Sensors, connected directly to the water detection module of the Air Handling Unit microprocessor control system, are located in: - - Condensate drain pan detecting undue water level. - Underfloor water tape, supplied loose with 5 metres of cable.

When water is detected, the Air Handling Unit's alarm system is activated and disables humidifier function.

Sump Pump Where, due to location, it is not possible to gravity drain units, a sump pump can be fitted to collect any condensate and pump it to the nearest convenient drain point (maximum available pump head 5.7 metres). For units fitted with humidifiers, a larger capacity sump pump is available to accommodate the additional discharge of hot water during humidifier drain down cycles (maximum available pump head 7 metres). Please note that when using a sump pump a minimum of a 200 mm high plinth is required.



VRF System To provide energy saving and thereby limit emission of greenhouse gases that contribute to global warming, models 23 and above are supplied with the variable refrigerant flow (VRF) compressor configuration. By applying these models to smaller loads, even greater energy savings will be realised, due to the very high part load efficiency.

Electronically Controlled Fans For applications where high airflow is not required and noise is a major consideration, then fans with variable speed motors can be fitted. The motors are 3 phase variable frequency but only a single phase feed is provided. The airflow provided by the fan(s) is determined by a 0 – 10 Vdc signal that is generated from the cooling demand via the controls. The lower the cooling demand the lower the airflow and vice versa. For this option, a reduced heating capacity will be necessary.

Condenser Fan Pressure Switch A Condenser Fan Pressure Switch can be fitted to the Unit to replace the standard fan speed controller on "A" versions.

Screwed Water Connections BSP screwed fittings supplied instead of the standard copper solder connections on “W” and “C” versions.

Hot Gas By Pass "A" versions can be fitted with hot gas by pass compressor capacity control. This consists of a hot gas control valve in the by pass line between the discharge line of the compressor and the evaporator coil suction header, with the sensing line fitted in the suction line.

Refrigerants Alternative refrigerants R134a and R410A are available as standard options on request.

Hand/Auto Switches A hard wired switch assembly, fitted in the electrical control panel can be used as manual override or as automatic control function, and is intended as an aid to commissioning engineers.

Run Status Run Status is achieved by volt free terminals, located in the electrical box, for remote monitoring of the unit run (fans) operation.

Ancillaries and Options GEA Close Control T-Range


Controller Remote Display The C3-05 Controller Display can be supplied remote from the Air Handling Unit, complete with interconnecting cable up to 1 kilometre.

Monitoring Display The Monitoring Display can be connected to a network of C3-05 Controllers to enable complete Air Handling Unit monitoring.

Electronic Expansion Valve (EEV) On DX units the EEV option can be fitted to replace the standard TEV. This consists of a valve, electronic driven module, pressure transducer and temperature sensor per refrigerant circuit.

Discharge Pressure Transducer On DX units a pressure transducer can be fitted to monitor the discharge pressure. It is recommended that the EEV option it fitted with the Discharge Pressure Transducer.

Remote Temperature and Humidity Sensor The temperature and humidity sensors Unit, fitted with the required length of cable (up to a maximum of 25 metres), can be supplied remote from the Air Handling.

Winter Start Kit (ELATE) Generally recommended for temperatures between –25 °C and –40 °C, and comprises horizontal type liquid receiver with trace heater and pressure relief valve situated in a special section below the air cooled Condensing Unit / Condenser. However a base section will be required and will increase the overall height of the horizontal blow Condensing Units / Condensers by 400 mm.

Trend Interface Card The Trend interface is a small pcb which can be plugged into the C3-05 controller to provide it with Trend network capability.

The interface needs to be configured in order that the required controller variables are linked to appropriate Trend parameters; these then become accessible via the Trend network using standard Trend (text) communications. The interface provides CNC functionality.

- Flexible number of configuration modules - Peer to peer communications (IC Comms) - Suitable for field installation - Display and directory modules



RS232 Serial Card The RS232 Serial Card is used to interface the C3-05 controller directly to a standard HAYES modem. The following hardware signals can be managed: - Output, “request to send” (RTS) in parallel to “data terminal ready” (DTR). - Input, “carrier detected” (CD).

The maximum baud rate is 19200.

RS485 Serial Card The RS485 Serial Card is used to interface the C3-05 controller to an RS485 network.

The card guarantees the optical isolation of the controller from the RS485 serial network. The maximum baud rate is 19200 (adjustable in software).

Lonworks Serial Card

The LonWorks Serial Card is used to interface the C3-05 controller to a Lonworks network.

The type of interface on the LonWorks network side is: - PCO20000F0 – interface to FTT-10A 78 Kbs (TP/FT-10).

The baud rate of the C3-05 controller must be set to 4800.
