AHU’s with Rotary Thermal Wheel Heat Exchanger

Efficient AHU’s with Rotary Thermal Wheel HEX

Kesair Rotors are Your choise, when You need performance in a compact package.

  • Suitable for air volumes between 0,1–10 m3/s.

  • Units can be assembled as a single entity or in two separate parts that lock together into an entity in the final location. This makes it easier to hump them into place. Types 580 – 5100 (air volumes 8 to 10 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 both in vertical and horizontal air channel layout.

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

    • ALRV-80XH (air volumes between 0,1–0,25 m3/s). Supply air channel on the top and side of the unit.
    • ALRV-100-500X and AVRV-515-520X (air volumes between 0,15–1,2 m3/s). Supply air channel on the top and centre of the unit.
  • Horizontal air handling units for air volumes between 0,19–10 m3/s. Exhaust channel can be constructed facing upwards in these models, if so requested.

    • Small units ALRV-80-500 (air volumes between 0,19–1,1 m3/s).
    • Large units AVRV-515-5100 (air volumes betweene 1,1–10 m3/s).
  • Units with electric heaters are available as vertical assemblies for air volumes between 0,1–1,2 m3/s and horizontal assemblies for air volumes between 0,19–1,2 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 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
