For all non-flooded R22 systems operating at high, medium, and low temperature, down to -20ºF evaporating temperature.

RS-44b advantages:

• RS-44b has the same flow rate as R22
• RS-44b operates at a similar discharge pressure as R22 and lower pressure than R407A & C, R422B & D, R417a and R427A.
• RS-44b has the benefit of lower energy consumption;
• RS-44b operates at near cooling capacity of R22 in both A/C and Refrigeration applications down to -20⁰F evap. temp
• RS-44b is the lowest GWP HFC R22 replacement on the market at 1664 TAR and is Zero Ozone Depleting.
• If a service technician inadvertantly mixes RS-44b with R22 there will be no harm to the system components or system efficiency. We know this to be true because in Europe, where there are no regulations against mixing refrigerants, our European sister company has tracked these developments. In the USA, the EPA does not permit or condone the intentional mixing of refrigerants.
• RS-44b is good for cap tube and TXV systems. It has been operating in all types of systems with all types of compressors worldwide since 2013.
• RS-44 is produced in Texas, the UK and Spain.
• RS-44b requires no oil or system component changes
• RS-44b is certified A-1 by ASHRAE (non-toxic and non-flammable)

For R22 replacement in medium and low temperature applications and in chillers with flooded/recirc. evaporators with saturated suction temperature of 19ºF and below, such as ice rinks, cold storage, chemical plant process cooling and more.

RS-45 advantages:

• Capacity: RS-45 (R434a) is unique in being a capacity match for R22 across the range of applications where R22 is commonly found. No other refrigerant mirrors the capacity of R22 at low temperature (-31 F/ -35 C evap) and high temperature (+45 F/ +7 C evap).
• Coefficient Of Performance: RS-45 (R434a) has a Coefficient Of Performance (COP)which matches R22.
• Glide: RS-45 is a near azeotropic blend with a very low glide of 1.5 C mking it the best alternative in R22 flooded/Recirc. evaporators/systems.
• Compression Ratio: RS-45 has a compression ratio which matches R22 across the range of applications where R22 is commonly found.
• Lubricants: RS-45 is suitable with mineral oil ( MO), alkylbenzene (AB) and synthetic oils like polyolester (POE) and polyalkyglycol (PAG) oils. The ability to use mineral oil both reduces cost and avoids the use of hygoscopic synthetic oils which can absorb moisture during maintenance and leaks. POE oil also compromises seals and gaskets resulting in leaks.
• Other RS-45 Attributes: Non-flammable, Zero ODP, similar discharge pressure as R22 and considerably lower discharge temperature than R22; which provides significant operating benefits including a much lower risk of oil degradation.

For systems using R404

RS-50 (R-442A) refrigerant is compliant with the new European regulations due to its low global warming potential (GWP). At a GWP of 1888, RS-50 is less than 50% compared to R-404A and R-507. Additional advantages when compared to R-507, R-404A and the other HFC solutions currently on the market are:

• RS-50 has up to 30% higher cooling capacity compared to R404a
• RS-50 offers a much better coefficient of performance (COP) at low temperatures
• The heat exchangers have better heat transfer, reducing the operating time
• of the compressors
• Energy savings from RS-50 lead to quick return of investment
• Current system owners have already seen energy savings of approximately 25%

The systems that were originally designed for or converted to the refrigerants R-404A, R-507, R-407F, R-407A, can easily be replaced by RS-50, with no important modifications necessary. This is a “drop-in” direct conversion, without changing the type of oil or any of the main components. The only modifications necessary are:

• Adapting the temperature of the set points to RS-50
• Changing the aperture of the expanson valves, due to mass flow of RS-50 being 40% lower than R404A
