Compact supply air unit with integrated electric air heater, EC motor, filter and controller, DN 250

Product 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.
  • Mounted in the housing downstream of the fan, as seen in the air flow direction.
  • Closed tubular radiator made of stainless steel.
  • Temperature sensor arranged downstream of the heat register in the flow direction with radiation protection plate.
  • 3-step power control of the electric heating register.
  • Safety temperature limiters switch off the electric heating register at a temperature of 75°C in the event of a fault. After the safety temperature limiters have been triggered, they must be reset manually.

Control panel

  • Separate control panel, incl. control cable, is included in the scope of delivery.
  • 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.

Fan

  • Motor/impeller combination.
  • EC motor.
  • Impeller mounted perpendicular to the air direction.
  • Impeller with backward curved blades.

Motor
