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 RDR flow regulator is a component that is installed inside a duct to achieve a constant flow rate in a pressure range between 50 and 250 Pa. It is used in ventilation and air-conditioning systems, in the extract or supply air.
The RDR volume flow controller can be adjusted during installation to a given volume flow. The RDR controller has graduations on the sides of the opening to illustrate the level of adjustment.
