We provide refrigeration system based on freon, including R404a, R507, R407C, R22.
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.
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.
We produce our compressor racks with world famous components
and?the world lastest technology. Each compressor rack is
standardly equipped with phase loss protection, reverse phase order
protection, over voltage/lack voltage protection, oil pressure
protection, high/low pressure protection, motor over load
protection, etc. This would enable our compressor racks to avoid
frequently startup/off and provide a stable and reliable
performance to end user.
High efficiency oil separating system. When power is on, there is
no need to add lubricating oil, the standard provided oil heater,
oil temperature controller and oil level switch, 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.
