The KCC/KCB ceiling-mounted air cooler series is adapted for use with A1, A2L and A3 refrigerants. This means that the series is approved for use with class A2L and A3 refrigerants. By adapting key components of the air coolers, the KCC/KCB series fulfils the requirements of EN378 and EN IEC 60335-2-89 (11.2023) and therefore represents low-hazard operation in the cold room.
