DewGas R-290

R-290 (Propane) is a refrigerant-grade hydrocarbon designed for new refrigeration and air-conditioning systems approved for HC refrigerants, and may be used as a low-GWP alternative to certain fluorocarbon refrigerants such as R-404A and selected R-407 series, subject to system design and regulatory approval. Classified as ASHRAE A3 (highly flammable), R-290 must be handled only by trained and authorized personnel and used strictly within approved charge limits and safety standards. It delivers high thermodynamic efficiency while offering very low environmental impact, with GWP ≈ 3 and zero ozone depletion potential (ODP). Application suitability, system compatibility, and compliance with applicable safety codes must be verified prior to use.

APPLICATIONS:

• Commercial Air-Conditioning & Commercial Refrigeration
• Domestic Air-Conditioning
• Industrial Refrigeration & Industrial Air-Conditioning

USAGE INSTRUCTIONS:

• Refrigerant may be charged in either liquid or vapour phase.
• Delivers excellent thermodynamic performance and high energy efficiency.
• ASHRAE A3 (highly flammable) refrigerant; handle only by trained and certified personnel.
• Charging, recovery, and servicing require special procedures and approved equipment.
• Ensure adequate ventilation, elimination of ignition sources, and use of approved tools.
• Verify compressor oil compatibility, system charge limits, and component suitability with the manufacturer.
• All work must comply with equipment guidelines, safety standards, and local gas regulations for storage, transport, and disposal.
