Over 20 years ago, REFFLEX® brought their first generation of flexible polyamide hoses on to the market that are now being used worldwide. These DN-2.0 mm and DN-5.0 mm hoses are suitable for use in HFC/HFO and in subcritical CO2 installations.

In a transcritical CO2 installation, temperature and pressure can become too high for polyamide hoses when connected directly to the discharge valve or cylinder head. To overcome this problem REFFLEX® brings two new types of hose to the market.
