AHU’s with Fixed Plate Heat Exchanger

Heat Recovery AHU’s with Fixed Plate Heat Exchanger HEX

These being our most popular models, we’d like to offer a great versatility within. They are suited for almost everywhere, pre-eminently steamy and damp situations, like kitchens, changing rooms, pool rooms and saunas.

  • Suitable for air volumes between 0,22–6 m3/s.

  • Units can be assembled as a single entity, or in three separate parts that lock together into an entity in the final location. This makes it easier to hump them into place. Types 530 – 560 (air volumes 3 to 6 m3/s) are so large that they will only be delivered as three-piece entities.

  • Handedness can be adjusted to right or left.

  • Additional supply air heating with fluid coils or electric heaters.

  • Control panel includes eighter just terminal strip, terminal strip and switchboard or terminal strip, switchboard, and automation.

  • Available in both vertical or horizontal channel layout.

  • Vertical air handling units for air volumes between 0,22–2,1 m3/s.

    • ACV 80-1000XH (air volumes 0,22–2,1 m3/s). Supply air channel on the top and side of the unit.
    • ACV 100-600X (air volumes 0,28–1,1 m3/s). Supply air channel on the top and centre of the unit.
  • Horizontal air handling units for air volumes between 0,36–6 m3/s.

    • Small units ACV 100-600 (air volumes between 0,9–1,35 m3/s).
    • Large units ACV 515-560 (air volumes between 1,5–6 m3/s).
  • Units with electric heaters are available; as vertical assemblies for air volumes between 0,22–2,1 m3/s, and horizontal assemblies for air volumes between 0,36–1,2 m3/s.


The exterior of each of our machine has been built with two layers of steel and insulated with 50 mm thick rock wool layer in between. The components include fluid coil or electric heater for heating, airtight dampers, filters, control panel and fans with EC-motors. We equip the assemblies with the necessary sensors for air pressure, velocity, quality and temperature. Or – If it pleases You, we install the ones you provide.


  • Prefilters for coarse dust and dirt
  • Cooling system for hot summer months, with chilled water air conditioning or direct expansion (DX) air conditioning
  • Air preheating system for cold climates. This helps the fixed heat recovery system not to freeze over in harsh conditions. Alternatively, You may choose an automatic plate refrosting system with defrosting damper and bypass damper
  • Air rotation damper, that rotates the indoor air
  • Silencers
  • Thermostatic shunt mixing loop and operating pump
  • Variety of valves and gauges for managing the air pressure, velocity and quality
