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
- 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.
- Worry saving
- Less maintenance and repair is needed. All accessories we used are word famous brand with high quality and performance
- Our product doesn't need person to watch the operation, it could turn on and off automatically, adjust the load, record running data, remote control, and fault diagnosis
- With complete protection system against overload, overheat, HP, LP etc, the unit could work normally even in very bad conditions
- Easy operated CAREL controller or PLC controller are both available
- Intelligent cloud mode is available without extra charge for Product with PLC controller, it provides more detail on running status, easy monitorby mobile phone or iPad, andmore details for our technician to give you technical suggestionsremotely
- Energy saving up to 35%.The design makes the unit automatically change the working numbers of compressor depending on system load, which can save your running cost.
