why CIC system ?
happy new year to all of you.
I have a blast freezer 4H-15.2 Bitzer compressor without CIC system ,room temperature -35°C by using R22 refrigerant .
I realised the compressor oil become brown colour . Last oil changing was 1 year ago . some people said i need to install CIC system to prevent oil colour changing .
could any body guide me where to get the information or article about CIC system and VARICOOL system ? when i need to fix those system and why install head fan ?
I have tried on GOOGLE search but still can not get what i want .
Your help would be much appreciated .
Regards
oilzee

Re: why CIC system ?
Varicool or CIC depend on size of compressor!
For R22 and room temperature -20 evaporation will be around -28°C and that require CIC or Varicool as well as aditional head cooling.
You cannot use capacity control when you have CIC !
