RS-52 Refrigerant, R502 Replacement, 24 Pounds

R502 Replacement 

ComStar's RS-52 (R428A) is a near azeotropic refrigerant blend with Zero Ozone Depletion Potential. RS-52 can replace R22, R502, and the interim ozone depleting blends (R402A, R403B, R408A, etc.). Replacing these refrigerants with RS-52 is easy because there are no necessary changes to the existing lubricant or the system, other than an adjustment to the expansion device in some cases. RS-52 is targeted towards lower temperature applications.

RS-52 (R428A) is compatible with all lubricants, including the traditional oils such as mineral and alkylbenzene oils, but also with the new synthetic polyol ester lubricants. Converting to RS-52 is a straightforward process which avoids a costly, and often technically unsatisfactory retrofit like draining the oil from the system replacing the seals.

RS-52 (R428A) is a capacity match for R502 and has a temperature glide of less than 1°C. RS-52 can also replace R22 in systems which are rated for R502. 

Performance Characteristics

• RS-52 is non-flammable and non-toxic
• RS-52 has Zero Ozone Depletion Potential
• RS-52 is a high-capacity refrigerant
• RS-52 is a close performance match for R502
• RS-52 can replace R22 in low-temperature applications
• RS-52 is compatible with MO, AB & POE lubricants
• RS-52 has lower discharge temperatures
• RS-52 is a near azeotropic blend
• RS-52 is suitable for new & existing equipment
• RS-52 is a capacity match for R502
• RS-52 has a low-temperature glide < 1°C
• RS-52 does not require any changes to hardware

The high capacity of RS-52 qualifies its use as a direct replacement for R502, R403B (69L), R402A (HP80), R408A (FX10) & R411B without any loss of performance. Discharge pressures are similar to R507 and R404A. The high capacity of RS-52 at low temperatures is a prominent feature of this new refrigerant.
