Mortuary Cooler Refrigerants: A2L vs R-290

Mortuary Cooler Refrigerants: A2L vs R-290

A refrigerant name, its safety class and the equipment listing are three different pieces of information. Before specifying a mortuary cooler, obtain the exact refrigerant designation and the installation instructions for the selected refrigeration unit. Do not select or convert equipment from a generic “low-GWP” label.

A2L is a safety class; R-290 is a refrigerant

A2L identifies a lower-flammability safety group. R-290 is propane and belongs to the A3, higher-flammability group, not A2L. EPA's flammable refrigerants technical presentation compares those groups. They are not interchangeable designations or drop-in replacements for one another.

Ask for the model-specific record

• Refrigeration manufacturer and complete model number, separate from the cooler cabinet model.
• Refrigerant designation, charge and required hazard labels.
• Whether the system is factory-sealed or field-assembled, with applicable installation instructions.
• Approved room conditions, service clearances, ventilation and any required mitigation or detection.
• Electrical schedule and the qualified contractor responsible for installation and startup.

Low GWP does not establish complete compliance

EPA restrictions depend on the equipment sector, product or system type and applicable dates. EPA's Technology Transitions tables distinguish those categories and direct readers to the regulations. A refrigerant's safety class by itself does not certify a complete installed mortuary cooler.

Use the selected equipment, not an assumed retrofit

Current AMC listings describe their supplied refrigeration configuration. Use the model-line specifications to start a comparison and request the current equipment schedule before ordering. Do not charge an existing system with a different refrigerant or reuse components without manufacturer and qualified-contractor review.

For an existing unit, send photographs of the cabinet and refrigeration nameplates through the PO / RFQ builder. This guide is purchasing information, not a refrigerant-handling or conversion procedure.
