screw parallel units R404A

Low temperature parallel units

Low temperature Bitzer parallel units

 

Product features:

Up to -45 degree Low temperature Bitzer screw parallel units R22 R404A

A, Parallel refrigeration unit Energy efficient units to provide as much energy regulator series, smoothly energy regulator almost comparable with frequency steeples adjustment. Greatly saving energy.

B, Each combination condensing unit uses a microcomputer controller, to ensure maximum output energy unit dynamically match the actual system load. 

C, Parallel refrigeration condensing units Long lifespan, high efficiency using new oil subsystem to ensure adequate lubrication, equipped with hydraulic monitoring device. Microcomputer control balance each compressor running time, precise control of computer start and stop delay. Ensure that each compressor uniform wear and extend machine time. 

D, HVAC Parallel condensing unit Comprehensive security features, phase protection functions, including phase, reverse phase, high pressure, voltage, and phase balance. 

E, Compressor electronic motor overload protection device.

Electronic low level detection and alarm devices. Oil pressure alarm, high alarm.
