ZKB 15/10 MFA - RR 1b

ZKB 15/10 MFA - RR 1b mobile operating system

Tent air conditioning units in split design for 1b cleanroom class operating tents

The Weiss ZKB 15/10 MFA - RR 1b air conditioning unit has been developed for air conditioning of medical and rescue tents in addition to fully equipped operating tents. The unit has been tested and approved in accordance with DIN 1946-4-2008-12 and conforms to cleanroom class 1b. The unit is equipped with three-stage filtering with HEPA filter box.

Cooling capacity is maximum 11 kW and heating capacity is maximum 7.2 kW. The system can be optionally expanded with fuel-powered heating and a capacity of 30 kW. Even with an ambient temperature of -32°C, comfortable temperatures can be achieved. A heat carrying medium is used to transfer heat into the tent where it is supplied to the ventilation system. The indirect heating system prevents emissions from entering the tent.


  • Split design
