1)Adopt world famous Bitzer ECOLINE series semi-hermetic piston compressor,with high reliability; 2)Multi compressors were parallel connected to provide bigger capacity sharing same discharge   pipe,suction pipe,condenser, liquid receiver etc; 3)Compact design for easy installation and small installation size; 4)Multi stage energy adjustments according to cooling capacity to  save operation cost; 5)Can meet medium and low temperature requires. 6).Other kinds of power supply not mentioned in the specification  is optional,such as 220/440/460V-3Phase-60Hz. 7)Appliction: Meat, vegetable, fruit cold storage, food prepare workshop, chemical cold room, medicine cold room, freezer tunnel, blast freezer, walk-in freezer, supermarket food display cabinets, fresh keeping, etc
2.Characteristics: 2.1 Variety of options Piston type 2 compresspr parallel unit Piston type 3 compresspr parallel unit Piston type 4 compresspr parallel unit
Adopted to multiple refrigerant R404a, R507, R407C, R22. Â 2.2 Stable & Reliable: Â The units are equipped with world famous brand high quality compressor and components, following the latest design, the perfect combination provides a safe and reliable system. Â The unit comes standard with a controller that can effectively avoid turning on/off the motor frequently as well as safety protection modules including the following: Phase loss protector, Inverted sequence, overvoltage protector, undervoltage protector, oil pressure, high pressure, low pressure, motor overload.
2.3 High efficiency & energy saving  Because of a huge demand difference between seasons for refrigerating capacity, the unit must have a high level control for capacity, so that the unit can keep running under high efficiency mode. The average parallel unit efficiency, according to different refrigeration system is 30% higher than single compressor unit.  Using multiple compressor parallel units can provide a multiple energy level control, the refrigeration output can be dynamically allocated more smoothly according to actual situation. With high efficiency oil separator, only a small amount of lubricating oil enters the system, this largely brings up the heat exchanging efficiency.
2.4 Compact & nimble  Components such as compressor, reservoir, gas-liquid separator, oil separator, electrical control equipment ,etc are all centralized, making sure every inch of the space is fully used.  The unit has a compact structure, the space saved during assembly can provide more space for commercial use, benefiting the end user with extra profit.
