Stable & Reliable Performance

 

 

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.

 

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.

 

High efficiency oil separating system. When power is on, there is no need to add lubricating oil, 

the standard provided oil heater (for screw unit), oil temperature controller (for screw unit) and 

oil level switch (for screw unit), etc. can protect the function.

 

The PLC controller is a standard provided component. It can automatically decide the compressor

 quantity to be used based on actual need of refrigerant capacity, average the running time 

between each compressor, save the power. All of these will guarantee an over 30% longer 

usage than single compressor condensing unit.

 

It has a unique low environment condensing pressure monitor system which guarantees a stable

 functioning when there is a low ambient temperature, lack of oil feeding or oil flow warnin

 

High efficiency gas liquid separator is used, with a unique pipeline design, it can effectively

 minimize the possibility of liquid strike. 

 

The “Pressure Vessel Certificate” approved reservoir is provided as well as the safety relief valve.

Fault isolation device is served so that when a certain compressor breaks down, the rest of the

 unit can keep running appropriately, making sure that client has enough time for repair and

 replacement.

 

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.

 

The PLC controller monitors running compressors quantity, it maintains a maximum use rate

 even when only parts of the compressors are functioning.

 

PLC controller can be set with the best running curve (maximum & minimum power comsuption),

 to same as much electricity as possible.

 

With “modularized design” the risk during construction can be largely reduced, construction

 period can be shortened, improve the product quality controllability.

 

Compact & Nimble Structure

 

Components such as compressor, reservoir, gas-liquid separator, oil separator, economizer,

 intake manifold, fluid supply manifold, electrical control equipment 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.

 

Easy operation & convenience

 

With PLC safety auto control, client can program with touch screen, the graphical control

 interface can intently show the running status, recording data, parameter settings and false 

alarming, easy for operation.

 

The reserved remote communication interface can help customer to monitor remotely.

 

Thanks to the print output interface, customer can print the running history data of the unit and

 the system.
