In apartment buildings, roof extraction units are often necessary to ensure clean, high-quality indoor air. Ventilation in apartment buildings is often set at a default level, even though the load varies. This results in a significant loss of energy. Ventilation applications in apartment buildings are easy to implement by using HK Instruments’ measurement devices. Our cost-efficient solutions do not need to be supported by an expensive building automation system.

DPT-Ctrl-2SP (1) keeps the air volume in the laundry facility at the desired standard value by controlling the EC exhaust fan. RHT-1R (2) monitors the air humidity and causes DPT-Ctrl-2SP to increase capacity when air humidity increases. CDT-MOD-2000-DC (4) monitors the air quality in apartments, and DPT-Ctrl-MOD (3) actively adjusts the exhaust fan. Both devices communicate seamlessly with the building management system through the Modbus interface
