Description
Description
DESCRIPTION
  • The VUT WH air handling units with a water heater are used in ventilation and air conditioning systems in commercial, office and other public or industrial premises that require an economical solution and a controlled ventilation system.
CASING
  • The casing is made of aluzinc steel with 25 mm thick mineral wool heat- and sound-insulating layer.
FILTER
  • Two G4 panel filters for extract air ventilation are supplied with the unit.
FANS
  • The units are equipped with supply and exhaust centrifugal double-inlet fans with forward curved blades and built-in thermostat with automatic restart.
HEAT EXCHANGER
  • The heat exchangers have high efficiency and are made of polysterene.
  • The unit is also equipped with the drain pan for condensate drainage.
HEATER
  • The water heater.
  • The water heaters are designed for max. operating pressure 1.0 MPa (10 bar) and max. heat medium operating temperature 95 °C.
AUTOMATION AND CONTROL SYSTEM
  • 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.
CONTROL AND PROTECTION FUNCTIONS
  • Control from the control panel: switching on/off, threespeed fan selection, selecting heating/cooling modes (if connected to duct heater); room temperature display.
  • Maintaining supply air temperature set from the control panel by controlling the circulation pump and actuating the heat medium regulating valve; input from the heat medium flow switch (pump alarm).
  • Safe start-up/ shutdown of the fans, warming up of the water heater before start-up; return heat medium temperature control when the fan is off.
  • Freezing protection of the water heating coils by the exhaust temperature sensor and the return heat medium temperature sensor.
  • Control of the compressor and condensing unit of the water cooler by the room temperature sensor (for the models equipped with a duct air cooler).
  • Actuating the external air dampers with a return spring.
  • Unit operation according to week schedule (set at the system setup).
  • Unit shut down at signal from the fire alarm system.
  • Smooth bypass damper control in the bypassing mode to prevent the heat exchanger freezing.
MOUNTING
  • 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.
