DewGas HC Blend

HC Blend is a zeotropic hydrocarbon refrigerant blend of Isobutane (R-600a) and Propane (R-290), supplied under the DewGas product range and intended for use only by trained HVAC&R professionals in compliance with applicable safety standards and regulations. Developed for refrigeration and air-conditioning applications where hydrocarbons are permitted, it may be considered as a low-GWP alternative to R-12 and R-134a, subject to system design, charge limits, and regulatory approval. HC Blend operates at pressure levels generally comparable to R-12 and R-134a and is suitable for small commercial refrigeration and air-conditioning systems approved for hydrocarbon use. It is compatible with common system materials, heat exchangers, expansion devices, and lubricants such as MO, AB, and POE, subject to manufacturer verification. Classified as ASHRAE A3 (flammable), HC Blend must be handled, charged, stored, and serviced strictly in accordance with safety codes and statutory requirements.
