Oil-Injected Variable SpeedRotary Screw Air Compressors

HSC FRECON 18-275AIR / OIL AFTERCOOLERLong life and trouble free operation with “bar/plate” type aluminium combi-cooler. Coolers is selected to provide trouble free operations even in high ambient temperatures.

DRIVING SYSTEMBelts are selected according to 25.000 operating hours. Pulleys with taper bush can be easily disassembled and assembled. Easy belt tensioning system provide trouble free operation.

CONTROL PANEL AND CUBICLEElectronic LCD panel indicates any type of operational and service activites in the easiest way to make everybody understand perfectly. Different type of safety systems provides protection for any type of risks.

All electrical components in the cubicle are chosen from well known brands all over the world.

VIBRATION PADSpecial rubber vibration pads eliminates vibration and problems it may cause.

Hertz Screw Compressors are designed to serve you trouble free, operation for long life time and each components are selected carefully in accordance with this purpose.

AIRENDHigh efficiency airends manufactured by one of the leading airend manufacturer in the world. Our airend design is based on new rotor profile and lobe combination, which is the result of long experience of screw compressor performance, new CAD Methods and utilization of modern production technology.

The new rotor profile with minimized “blow hole” reduces torque requirement, which means lower power consumption.

AIR INTAKE SYSTEMReplaceable dry type paper filter element eleminate dusty ambient problem.

Piston controlled intake valve is chosen right size, which means high capacity and low power consumption.

AIR/ OIL SEPARATIONEffective design provides three stage separation.

Long life separator elements reduce oil in compressed air less than 3 ppm.

Spin-on elements provides fast and easy separator element replacement.(HSC FRECON 18-37)

THERMOSTATIC VALVE4 ways thermostatic valve provide trouble free operation in low ambient temperatures.

30% SAVING

Standard air compressors are designed to operate continuously at full capacity. However depending on the application, the need for compressed air varies significantly. Research has shown, that on average, only 50 – 70 % of the compressor capacity is utilized. HERTZ FRECON models within the Variable Speed Controlled Compressor Series, give you the advantage to reduce energy costs by up to 35 %.

These two figures show a comparison of energy consumption between same sized ON/OFF-load and FRECON Compressors. The example consists of cost in 5 years, compressors running 6000 hours/year with an average load ratio of 60% and an energy price of 0.08/kWh.FRECON shows remarkable savings in energy and also in total costs of the compressor. The payback time of the FRECON unit is only 1.4 years.

By the support of a frequency inverter, FRECON Series Compressors adjust the motor and airend speed in accordance with the air motor and compressor unit airend speed demand of the factory. As seen in the chart, energy consumption keeps decreasing almost linear in proportion with the capacity, overtly a 35% saving in energy consumption is possible. Beside that, the wide capacity ranges allow the FRECON Series compressors to supply the required amount of pressure, continuously and at a constant level. With that method, not only an extra amount of energy saving is provided, but the possibility of unfavourable pressure change effects on some critical equipments is prevented as well. The use of the ‘Soft Start System’ in FRECON Series Compressors extends the motor service life and avoids the negative effects of the high start current on the energy system. In addition, ‘Soft Start System’ lets the motor get started as many times as needed, and the short idle time periods give an extra energy saving.
