Cold Room Compressor Rack Unit Danfoss Hermetic Scroll Type

Cold Room Compressor Rack Unit Danfoss Hermetic Scroll Type

Features:

• 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.

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
• system.

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.

We also develop and program our own PLC control system, it can automatically control the running compressor quantity according to refrigeration need so that the system can save more energy and can provide 30% more use life than single compressor condensing units. With PLC auto control graphical interface, customer can operate with read the running status, data, parameter and error alarms easily. Optional remote control communication port is also provided, so that customer can monitor in their office. 

We focus on high efficiency daily mangement and QC to guarantee stable quality. By following ISO9001:2008, we have strict tracking system of each order, all welding are proformed with argon charged in the system to prevent welding waste going into the system. All condensers are delivered with high pressure gas charged when they delivered. Each final compressor rack will go through no-load test before packaging.

We welcome friends from all over the world, together let's serve the world with more environmental, efficient and cost effective refrigeration unit.
