six.FAQ
Q:Why compressor rack is much better than single compressor?
In contrast to one compressor, compressor rack is far more safer, more energy-conserving, less difficult sustaining and set up. Value is little greater than one compressor, but for long phrase considering, it is very affordable efficiency.

Q:How does every compressor operates on compressor rack?
CZPT rack works based mostly on the cold place loading. If the lower loading in the chilly space, 1 compressor runs when far more loading inside of the chilly place, two or a few compressors operate.

Q:If 1 compressor was improper, will it affect the operating of other compressor?
No, as compressors can perform independently, so one compressor mistaken will not influence other compressor’s operating.

Q:How to recognize the CZPT new CZPT compressor?
If the CZPT compressor value is 40% decrease, it might almost certainly not CZPT new compressor. Also, every single CZPT compressor have one stability code, you could examine it on CZPT web site.

Q:How to distinguish among the CZPT new and fake CZPT compressor?
Every compressor has a unique nameplate with QR code. Use the cellphone to scan the code, the end result will show on the phone from CZPT company techniques. Any mobile phone can do. CZPT new, outcome is productive and faux compressor fail.

Q:Where are CZPT compressor manufacturing bases found?
ZheJiang China, CZPTica, Germany, Egypt and so on. They follow the German headquarters stringent quality manage system. We acquire CZPT compressor from CZPT factory in ZheJiang . 

Q:How many sorts of CZPT compressors?
Semi-airtight(ECOLINE series),Two stages semi-airtight, Semi-airtight screw compressor, Airtight screw compressor.

Q:What is the Bizter life time?
Normally 8 many years at the very least. But need upkeep to make certain high performance.

nine. Installation instructions and project photograph
–Installation
a) The unit can be lifted by fork automobile or sling. If the sling is employed, it must not contact any pipes or electrical factors in procedure.
b) The unit must be set up preserve in degree in an setting with excellent air circulation, far absent from warmth resources, places of large temperature and higher humidity. If the device is put in in the open air, a shelter is essential to keep the unit from direct sunlight glow and raining. Proper area shall be left for routine maintenance.
c) The area for the unit must be good for the air flowing, the temperature of the space have to not be greater than 40ºC.
d) For the drinking water cooled technique, sufficient cooling tower, pumps and pipes, h2o flowing change need to be chosen. In scenario too modest drinking water or no drinking water, the system can commence protection routinely.

–Pipe link
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 stage part of the discharging pipe need to be inclined to condenser.
c) Resolve the pipe to reduce the seem and vibration level.
d) In procedure of refrigerant pipes, neutral fuel of reduced force is to be loaded to avoid the pipes from internal oxidation. Dry nitrogen is recommended as the security gas.   
e) Clear the refrigeration technique with dry nitrogen preserve the program free of filth, oxid and overseas matters.
f) For the main suction line a U formed pipe component for oil returning must be established below the compressor an upside down U formed pipe element need to be established for every four meters in circumstance the unit is fastened greater than the evaporator. The suction line require be wrapped with heat insulation materials to maintain it from frosting and overheating.
