Kryon R290

Kryon® 290 (R-290) is propane used as a natural refrigerant in refrigeration systems. As a hydrocarbon composed solely of carbon and hydrogen, it has a minimal environmental impact: it does not deplete the ozone layer (ODP = 0) and has a very low global warming potential (GWP) compared to traditional HFCs/HFOs.

It is a highly flammable gas (safety class A3); therefore, it requires specific safety precautions during storage, handling, and system charging. Furthermore, the refrigerant charge in 'plug-in' systems is limited by regulations (typically up to approximately 150 g).

R-290 is primarily suitable for systems with small charges, such as refrigerated display cases, positive-temperature cold rooms, vending machines, and ice machines. The use of mineral oils in compressors can help manage solubility and moisture more effectively, avoiding issues associated with synthetic lubricants in hydrocarbon systems.

Refrigerant Code: R-290

Trade Name: Kryon® 290

Composition: Propane (Refrigeration Grade 2.5–99.5%)

Safety Class: A3 (highly flammable)

GWP: Very low (≈3 per IPCC; natural propane)

ODP: 0 (zero ozone impact)

Recommended Lubricants: Mineral oil specifically for hydrocarbons (to minimize moisture and solubility issues)

Safety Note: As an A3 gas, it is essential to follow strict safety procedures and observe charge limits in refrigeration systems.
