Lubricants

RS-24 can be used safely with both the traditional and new synthetic lubricants, and consquently there is no need to change the oil when replacing R12.

RS-24 eliminates the risk of a compressor burn-out which can occur by simply replacing R12 with R134a without reducing the mineral oil content in the system to the recommended maximum 5%. The solubility of RS-24 in mineral oil enables oil return to the compressor.

Existing Equipment

RS-24 can be added to a refrigeration or air conditioning system previously operating on R12 without changing the oil or making any alterations to the equipment. Because RS-24 has a lower density than R12 (and R134a), less product is required than the R12 it replaces (typically 90%).

With its ability to use traditional and synthetic lubricants. RS-24 makes the replacement of R12 in all applications simple, straightforward and cost effective.

New Equipment

RS-24 is also suitable for use in new equipment as a zero ODP replacement for R12.

Avoiding the use of expensive and hygroscopic lubricants reduces costs and significantly reduces the risk of ingress of moisture into the system.
