The EPA is proposing to list HCR 4141, HFO-1234ze(E), and R-516A as acceptable, subject to use conditions, for this end-use. HCR 4141 is a higher flammability refrigerant blend with each component in the A3 Safety Group. HFO-1234ze(E) and R-516A are lower flammability refrigerants, both in the A2L Safety Group.
