R 290 is the commonly known as high purity propane (C3H8), and typically at least 97.5% pure with minimal levels of critical impurities including moisture and unsaturated hydrocarbons. This makes it ideal for use in all types of refrigeration systems.
R 290 has a wide range of applications: commercial refrigeration, chill cabinets and vending machines, cold storage and food processing, industrial refrigeration, transport refrigeration, small air conditioning systems, large air conditioning and chiller systems, heat pumps and water heaters.
