Product Description

1.  Semi-hermetic screw compressor racks condensing unit refrigeration unit introduction.
This series products feature open type with semi-hermetic compressor racks, that is compact and pleasant looking, applicable to cold storage rooms. The applicable temperature ranges are: -5~-5ºC and and -25~-40 ºC. They can be used in medicines, agricultural, chemicals industries all other place where cold storage is needed

2. Semi-hermetic screw compressor racks condensing unit refrigeration unit features and Technical data:
1.Variety of options
Temperature: -5~-5ºCand -25~-40 ºC;Horsepower: 50HP ~ 375HP ;Applicable to multiple refrigerant R404A.R507.R22.

2.Reliable system
--The units are equipped the world famous brand compressor and compressor and components, professional technical engineer following the latest design, to create a safe and reliable system.
--The units 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 over voltage protector, under Voltage protector, oil pressure, high pressure, low pressure, motor overload.
--High efficient oil separating system, when power is on it's not need to add lubricate oil, the standard provide oil heater(for screw unit),oil temperature controller(for screw unit),etc. can protect the function.
--It has a unique low environment condensing pressure monitor system which guarantees the stable functioning when there is a low ambient temperature, lack of oil feeding or oil flow warning.
--The reservoir is provides 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 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 35% 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 compressor 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 and minimum power consumption),to same as much electricity as possible.
With "modularization design"the risk during the construction can be largely reduced, construction period can be shorted, improve the product quality control ability

4.Compact structure 
Components such as compressor reservoir, gas-liquid 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 alarming, easy for operation.
The reserved remote communication interface can help customer to monitor in different place . Thanks to the print output interface, customer can print the running history data of the unit and the system.

6.FAQ
Q:How to identify the original new compressor?
If the  compressor price is 40% lower, it may probably not original new compressor.
Also, each  compressor have one security code, you could check it on compressor website. 

Q:How to distinguish between the original new and fake  compressor?
Each compressor has a unique nameplate with QR code. Use the cellphone to scan the code, the result will show on the phone
from  company systems. Any phone can do. Original new, result is successful and fake compressor fail. 

Q:Where are compressor production bases located?
Beijing China, America, Germany, Egypt and so on. They follow the German headquarters strict quality control system.
We purchase  compressor from compressor factory in Beijing. 

Q:How many kinds of compressors?
Semi-hermetic(ECOLINE series),Two stages semi-hermetic, Semi-hermetic screw compressor, Hermetic screw compressor.

9. Installation instructions and project photo
--Installation
a) The unit can be lifted by fork vehicle or sling. If the sling is used, it should not touch any pipes or electrical components in operation. 
b) The unit must be installed keep in level in an environment with good air flow, far away from heat resources, places of high temperature and high humidity. If the unit is installed in the open air, a shelter is required to keep the unit from direct sun shine and raining. Appropriate space shall be left for maintenance. 
c) The room for the unit should be good for the air flowing, the temperature of the room must not be higher than 40ºC.
d) For the water cooled system, adequate cooling tower, pumps and pipes, water flowing switch should be chosen. In case too small water or no water, the system can start protection automatically.

--Pipe connection
a) Do not expose the mouth of the compressor and filtering - drier to the open air.
b) The level part of the suction pipe should be inclined an angle to the compressor; the level part of the discharging pipe should be inclined to condenser.
c) Fix the pipe to decrease the sound and vibration level.
d) In operation of refrigerant pipes, neutral gas of low pressure is to be filled to prevent the pipes from inner oxidation. Dry nitrogen is recommended as the protection gas.    
e) Clean the refrigeration system with dry nitrogen; keep the system free of dirt, oxid and foreign matters. 
f) For the main suction line a U shaped pipe part for oil returning must be set below the compressor; an upside down U shaped pipe part must be set for each 4 meters in case the unit is fixed higher than the evaporator. The suction line need be wrapped with heat insulation material to keep it from frosting and overheating.
