For Determining the Correct Amount of IceCOLD® To Install in All Refrigeration Equipment:

Chillers/Air Conditioners/Refrigeration Units

Rule #1

  • Look up compressor specifications online or call the compressor manufacturer and ask how many ounces of compressor oil go in the compressor; give the model # and serial#. (this could be on the compressor label)
  • Multiply this oil fill(oil charge) quantity by 10%.
  • For example, if a chiller has eight gallons:
    8 gallons (multiplied by 128 oz. per gallon) = 1024 ounces.
    Therefore 10% of 1,024 ounces = 102 ounces IceCOLD®.
  • If you cannot determine the number of ounces, see Rule #2.

Rule #2

  • Multiply the tonnage by one ounce.
  • On smaller residential DX systems this rule is acceptable. It is recommended that only rule #1 be used on chiller systems. A 3.5 ton splilt system will require 3.5 ounces of IceCOLD®. Any system that is less than 2 tons(ptac units or aircons) will always require a minimum of 2 ounces of IceCOLD®.

Rule #3

  • Never exceed 30% IceCOLD® to compressor oil charge.
  • Be sure the compressor oil in semi hermetic compressors is clean before adding IceCOLD®.

Rule #4

  • On all Screw type compressors/chillers you need to make sure that there is not a Coalescing Oil Separator. IceCOLD® does not allow compressor oil to coalesce.

Rule #5

  • On larger systems, it is always a good idea to perform an oil test on the unit and ask for maintenance records to give you a clearer idea on how well the system has been maintained as well as its current condition.
  • Questions to ask include: Are the compressor oil and filters changed regularly? Are the coils cleaned regularly?
