Use:
Meat, vegetable, fruit cold storage, food prepare workshop, chemical cold room, medicine cold room, freezer tunnel, blast freezer, walk-in freezer, supermarket food display cabinets, fresh keeping, etc.
Characteristics:
1. Variety of options
Piston type single-stage parallel unit(20HP~350HP), evaporating temperature 7.5ºC~-45ºC
Piston type double-stage parallel unit(16HP~180HP), evaporating temperature -25ºC~-65ºC
Screw type single stage parallel unit(80HP~600HP), evaporating temperature 5ºC~-45ºC
Screw type double-stage parallel unit(100HP~600HP), evaporating temperature -30ºC~-65ºC
Adopted to multiple refrigerant R404a, R507, R407C, R22.
2. Stable & Reliable:
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 warning.
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.
3. 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.
4. Compact & nimble
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.
5. 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.
