Adopted to multiple refrigerant R404a, R507, R407C, R22.
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
- 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
- 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
- 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
- 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
- The reserved remote communication interface can help customer to
- Thanks to the print output interface, customer can print the
running history data of the unit and the system.
