Dear Valued Customer,
We appreciate your interest in our innovative products.
As of January 1, 2018, The U.S. Environmental Protection Agency (EPA) requires buyers of regulated refrigerants containing CFCs, HFCs or HFOs to be certified technicians or registered wholesalers.
TECHNICIAN
If you’re a technician, you will be asked to complete a short form and upload your
license to complete your order in the cart.
WHOLESALER
If you’re a wholesaler, you’ll need to complete an application and upload a sales and use tax resale certificate. Once you’ve been approved (usually within two business days), you will be entitled to buy our products at wholesale prices.
Thank you!

ComStar International Inc.’s RS-51, with the ASHRAE designation of R470B, is new to the U.S. market. RS-51 (R470B) is the lowest GWP at 717 retrofit refrigerant to replace R404a and R507 in EXISTING in-place R404a and R507 systems.
RS-53 (R470A)
RS-53 (R470A) is EPA SNAP approved and A1 ASHRAE certified as non-flammable and non-toxic. The refrigerant does not require design modifications or component changes. RS-53 can operate with existing polyol ester (POE) oils present in R410A systems.
RS-53 is an HFO blend, which is the environmentally friendly alternative to the commonly used HFC blend in other refrigerants. Using RS-53 as a replacement is easy. Just use the same tools, test instruments, and recovery machines as you use with a R410A system.
ComStar’s RS-53 (R470A) can accommodate state and federal legislation as they phase out high-GWP refrigerants, such as R410A with a 2088 GWP.
RS-53 (R470A) is formulated to be trouble-free and works with all R410A compressors, system components and POE oils. RS-53 has similar properties to R410A, including discharge pressure, discharge temperature, energy efficiency, and cooling capacity. It all adds up to an ideal replacement.
R470A (RS-53) is suitable to replace R410A across a range of applications, including residential, commercial, and larger cooling systems. When retrofitting an R470A system with R410A, ComStar offers the following guidelines:
1
Ensure the right equipment is available (e.g., recovery unit and cylinders, container for recovered lubricant, vacuum pump, weighing scales, replacement drier, etc.);
2
Record baseline data to establish the normal operating conditions for the equipment;
3
Check the manufacturer’s specifications for the unit to find the recommended R410A charge in order to determine the amount of R470A (RS-53) to add;
4
Replace the filter/drier;
5
Having evacuated the system, liquid charge the unit with R470A (RS-53) up to 90% of the original charge amount of R410A and then compare to baseline data;
6
Switch on the unit and compare the baseline data, monitor sight glasses, suction line pressure and temperature, and discharge temperature; add additional R470A (RS-53) up to the recommended R410A system charge amount as needed;
7
Where a thermostatic expansion valve (TXV) is present, and for optimum performance, make adjustments to attain the sweet spot. This is not necessary for residential systems.
8
Check system thoroughly for leaks; and
9
Clearly label the system to show it contains R470A (RS-53).
