What the source says
( 10 ) Industrial process refrigeration systems, other than chiller systems, as follows: ( i ) Effective January 1, 2026, systems with a refrigerant charge capacity of 200 pounds or greater and with the refrigerant temperature entering the evaporator higher than −30 °C (−22 °F), that are not the high temperature side of a cascade system, using a regulated substance, or a blend containing a regulated substance, with a global warming potential of 150 or greater; ( ii ) Effective January 1, 2026, systems with a refrigerant charge capacity less than 200 pounds and with the refrigerant temperature entering the evaporator higher than −30 °C (−22 °F), using a regulated substance, or a blend containing a regulated substance, with a global warming potential of 300 or greater; ( iii ) Effective January 1, 2026, the high temperature side of cascade systems with the refrigerant temperature entering the evaporator higher than −30 °C (−22 °F) using a regulated substance, or a blend containing a regulated substance, with a global warming potential of 300 or greater; ( iv ) Effective January 1, 2028, where the temperature of the refrigerant entering the evaporator is greater than or equal to −50 °C (−58 °F) and is less than or equal to −30 °C (−22 °F), using a regulated substance, or a blend containing a regulated substance, with a global warming potential of 700 or greater; and
