What is this new R290 Refrigerant?

20May 2021

R290 refrigerant is a type of refrigerant that is used in refrigerators.
R290 is a refrigerant-grade propane that can be used in a variety of commercial refrigeration and air conditioning systems. It’s a highly pure propane with a low environmental effect and a nominal global warming potential (GWP), which means it doesn’t have any properties that could deplete the ozone layer. R290 is also the Environmental Protection Agency’s (EPA) favored hydrocarbon alternative to more toxic fluorocarbon refrigerants like R22, R134a, R404a, and R502.

Only approved technicians who have been properly trained and certified may maintain and repair R290 units.

Refrigerants based on hydrocarbons
Certain natural hydrocarbon refrigerants, in addition to R290, are used in a wide range of industrial refrigerators, freezers, and air conditioners. These don’t deplete the ozone layer and have a low global warming potential.

R1270 is a propylene-based refrigerant that can be used in place of R22 and R502.
R600a is an isobutane-based refrigerant that can replace R12 and R134a.
R290 vs. R600a (R290 vs. R600a)
R290 and R600a share a lot of the same characteristics. Both are safe, environmentally friendly, and flammable alternatives to fluorocarbon refrigerants. So, what exactly is the distinction between the two? Here are some key distinctions to be aware of.

Safety Recommendations for Hydrocarbon Refrigerants

WARNING: R290 refrigerant handling necessitates certified training and authorization. Only certified service agents with proper qualification can use the tips and procedures outlined in this article. Without proper permit, instruction, or qualification, performing these measures or any related repairs on equipment can be hazardous and void the manufacturer’s warranty. For more detail, approved technicians should consult the manufacturer’s instructions. Parts Town disclaims all responsibility for collateral loss, disability, or death caused by following these instructions.

Hydrocarbon refrigerants, unlike fluorocarbon refrigerants, are extremely flammable. As a result, technicians must receive adequate training and certification before handling them, as well as take extreme precautions.

On non-flammable fluorocarbon refrigerant-equipped appliances, NEVER use propane as a replacement.
When working with propane refrigerant, wear protective gloves, eyewear, safety shoes, and antistatic workwear.
Make sure the area you’re in is well ventilated at all times. Heat sources, electric devices, and places where sparks may occur should be kept away from the unit.
When working near propane refrigerant, don’t eat, drink, or smoke.
