Cold Room Compressor Rack Unit Danfoss Hermetic Scroll Type
- Ranges from 15~90 hp for both medium & low temperature.
- Refrigerant R22, R404a, etc.
- Fast temperature pull down capabilities.
- Much lower investment compared with same level of reciprocating type compressor unit, even with a
- spare compressor standby.
- Very easy maintenance. The compressor itself in non-repairable, so once it’s broken, just replace a
- brand new compressor, and the replacement work doesn’t require high technique and cost very little
- money and time.
- Since scroll type compressor doesn’t have reciprocating framework, so the structure is more simple,
- compact, light weight and with less components(especially easily damaged parts). The system is
- highly reliable.
- The system has minor force moment, it is very stable, have very little shaking, so that it is very
- convenient for automation.
- Within its refrigeration capacity range, it has relatively high efficiency.
- Quiet operation, can be used in residential area.
- Light weight and compactness compared with semi-hermetic compressors.
Ourfuture scroll type medium/low temperature parallel compressor unit is widely used in wine cellar,
walk-in freezer, meat freezer, ice maker, ice lolly
factory, beer factory, medium & small sized cold storage, etc.
The product include:
Electrical switchgear, Compressor, Oil separator, Oil tank, Oil filter, Oil level controller, Horizontal rotary

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.
- 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.
- 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.
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.
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
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.
