ZKB 15/10 MFA –RR 1B


The Weiss ZKB 15/10 MFA-RR 1b air conditioning unit has been developed to condition air within medical and rescue tents in addition to fully equipped operating tents. This particular unit has been tested and adheres with DIN 1946-2008-12 and conforms to cleanroom class 1b. The unit is equipped with a three stage HEPA with a HEPA filter.

This unit has a cooling capacity maximum of 11kW and a heating capacity of up to 7.2kW. This system can be optionally enhanced with a fuel powered heating capacity of up to 30 kW. Even with an external temperature of -32°C, comfortable temperatures can be reached. The heat-carrying medium is used for the transfer of heat into the tent where it is provided to the ventilation system. This prevents emissions from entering the tent.
