Lubricants

RS-52 is compatible with both the traditional and new synthetic lubricants so that there is no need to change the oil when converting to RS-52. RS-52 is suitable for use with mineral, alkylbenzene and polyol ester oils.

RS-52 avoids the costly and often technically unsatisfactory changeoever to the new synthetic lubricants required of a full retrofit to R404A.

No changes to hardware

RS-52 can replace R22 & other Ozone Depleting Substances at low temperatures without changes to the existing hardware. Approximately 10% less RS-52 is required to replace R22, & possibly a slight adjustment to the expansion device may be required. The changeover process is simple, straightforward & can be very cost effective in comparison to a full retrofit to R404A.

Discharge Temperature

RS-52 has lower discharge temperatures, particularly compared to R22, which provides considerable operating benefits including an improvement in the reliability of the system and avoidance of lubricant breakdown.

Discharge Temperature

Applications

RS-52 is suitable for use in applications where R22, R502, R403B (69L), R402A (HP80), R408A (FX10) & R411B are commonly found including, but not restricted to, supermarket display cases, ice machines, cold storage, transportation of foodstuffs, freezer cabinets, freeze dryers & environmental test chambers.

New Equipment

RS-52 with its rapid pull-down feature is suitable for use in new equipment with the added benefit of being able to be used with both the traditional & new synthetic lubricants.

Servicing

Because RS-52 is a blend, it should be charged into the system in the liquid as opposed to vapour form. Vapour filling is possible when the total cylinder contents are charged into the system. Because RS-52 is a near azeotrope it has a very low temperature glide of less than 1°C.
