  • Air handling units VUT EH with electric heater are the complete air handling units designed to provide both supply and exhaust ventilation with air filtering and heat recovery.

  • The exhaust air energy is used to heat up the supply fresh air through the heat exchanger.
  • All the models are designed for connection with Ø 125, 150, 160, 200, 250, 315 mm round ducts.
  • VUT EH – a range of compact energy saving air handling units (AHU) equipped with supply and exhaust centrifugal fans, cross-flow heat exchanger, electric heater and air filters.

  • Two incorporated G4 panel filters for extract air ventilation are supplied with the unit.

  • The electric heater at outlet from the heat exchanger is designed for warming up of supply air up to the set level if heat recovery is not enough to attain the set supply air temperature.

  • The casing is made of aluminum-zinc compound with 25 mm thick mineral wool heat- and sound-insulating layer.

  • The units are equipped with supply and exhaust centrifugal double-inlet fans with forward curved blades and built-in thermostat with automatic restart.

  • The electric motors and impellers are dynamically balanced in two planes.
  • The ball-bearings used with motors are designed for at least 40 000 hours operation and are maintenance-free.
  • The heat exchangers have high efficiency and are made of polystyrol. 

  • The unit is also equipped with the drain pan for condensate drainage.
  • The unit incorporates an integrated automation and control system with a multi-functional control panel with LCD display.
  • The standard delivery set includes 10 m connection cable for connection to the remote control panel.
  • The unit has the freezing protection function to prevent the heat exchanger freezing by means of actuating the bypass damper and controlling water heater.
  • As the temperature sensor warns of the freezing danger, the bypass air damper is opened and the intake air is directed through the air duct beside the heat exchanger.
  • As the heat exchanger is warmed the supply air temperature rises up to the set level while passing through the heater.
  • Meanwhile the warm extract air warms up the heat exchanger.
  • After the freezing danger is no longer imminent, the bypass damper shuts the bypass duct and the unit reverts to the standard operation mode.
  • Control from the control panel: switching on/off, speed selection, timer, faults;
  • Maintaining the set room temperature by the sensor on the control panel – smooth heating capacity control;
  • Three-speed fan speed control (low-medium-high);
  • Unit operation according to daily and week schedule (timer adjustable from the control panel);
  • Safe start-up/shutdown of the fans;
  • Electric heater overheating protection by the temperature sensor installed in the supply air duct and by two overheating thermostats, one thermostat activated at 60 °C with automatic reset and another thermostat activated at 90 °C with manual reset. Blowing of the heating elements for heat removing at the end of the heating cycle;
  • Filter clogging control by filter time.
  • The unit is designed for indoor mounting. While mounting the unit provide the correct condensate collection and drainage. 
  • Access for the unit servicing and filter cleaning is from the side panels on the left from supply air side.
  • For attenuation of sound generated by the fans it is recommended to install the duct silencer (refer SR) from inside before the unit.
  • For vibration absorbing it is recommended to install the flexible antivibration connectors (refer VVG) on both sides of the unit.
