Heating and Cooling / Facade Heating & Cooling Products
Ventilation units for mixing ventilation LG-ZM-L-B and LG-ZUM-M-LB, for horizontal floor mounting
Decentralized air conditioning via the building facade.
To air condition office and administrative buildings having facades with floor-to-ceiling glazing, Krantz supplies ventilation units for raised floor mounting; they provide the required minimum percentage of outdoor air and remove the internal cooling and heating loads. The unit type LG-ZUM-M-LB has an additional function with recirculated air.
Features:
- Outdoor air intake directly through the facade; return air extraction via central system
- Cooling and heating via air-to-water heat exchanger
- Cooling with outdoor air (free cooling)
- Mixing & displacement ventilation close to facade
- Energy-efficient EC radial-flow fan
- F7 class filtration of outdoor air
