Does anybody have any experience with the use of Polarising Refrigerant Oil Addatives for chiller compressors to improve heat exchange and so reduce energy usage? I am advised they do this by releasing oil build up in condensers?
PermaFrost,Frigaid, Polaroil,Frigitech, Polarshield? groups are marketing here in Hong Kong very aggressively... claiming energy savings at extraordinary levels up to 40%of preinjection usage
Q1 What is their track record?
Q2 Are any better then the other? D
Q3 Do they work long term?
Q4 Do they work at all?
Q5 Do they effect the life cycle of the plant?
