short description
Compact supply air unit with integrated electric air heater, EC motor, filter and controller, DN 200Product description
Features
- Compact supply air unit with filter, electric air heater and control.
- stepless fan control: Constant volumetric flow/ constant pressure/ constant speed/ temperature/ CO2 controlled.
- Operating mode and setpoint temperature can be selected directly on the control panel. Timer with time programme and filter monitoring integrated in the control panel.
- The control is designed in such a way that an exhaust air fan (optional) can also be integrated. Thus, a complete ventilation system with supply and exhaust air can be installed with the simplest of means.
- Error monitoring.
- Possibility of connecting temperature sensors and/or air quality sensors.
- Modbus interface for connection to building control system.
- Extended menu structure with several levels and authorization concept.
- Material: Sheet steel, galvanised.
- With sound-absorbing rock wool, laminated with silk glass, and double-walled housing for minimum noise level and the best thermal insulation.
- Air filter replacement in seconds without tools.
- Impeller with blades curved to the rear for optimised efficiency.
- Removable cover with clip-locks.
- Inlet and outlet side connection socket for direct installation in ventilation ducts.
- Time-saving mounting thanks to mounting tracks.
- With automatic fan overrun to protect against overheating.
- Can be switched on/off using external potential-free contact.
- IP 33 degree of protection. Exception: ECR 25-2 EC and ECR 31-2 EC IP 54.
Electric heating register
- Existing housing unit, provided with protective grilles on both sides
- Housing unit can be pulled out of the housing by loosening 4 fixing screws.
