Controllers of the CSR-B series are constant pressure regulators designed for cooperation with duct and roof fans with EC motors. By continuously controlling the fan speed, they ensure constant pressure in the ventilation ducting. Based on a PI controller, CSR-B controllers have the option to set a constant fan power and programmable upper and lower fan control limits. -
The aircycle 3.1 operates by efficiently recovering heat from the air extracted from wet rooms (bathroom, kitchen etc.) that would normally be expelled to the atmosphere. Suitable for medium to large dwellings and apartments.
