Air-handling units for small volumes of air


We manufacture a variety of vertical and horizontal package units equipped with a counter-flow or rotary heat exchangers.

Our AHU’s are designed for commercial premises, like schools, day-care centres, offices, and industrial buildings where the air exhange places more challenges and requires larger output than in a private accommodation does.

Kesair’s factory-tested heat-recovery units are prefabricated with electrification and automation. Inbuilt birect-drive frequency-converter-controlled fans are easy to adjust and energy-efficiant.

Operating is easy via control panels on the devices. Alternatively, AHU’s can be delivered as terminal strip units and linked easily to a central control and monitoring system in the destination. We also deliver assemblys without any electrical and regulation equipment.


  • Sheet-metal – mineral wool – sheet-metal construction, where 50 mm thick mineral wool works as heat insulation. Adjustable pedestals makes the unit sturdy and easy to install into place.
  • Tight fresh-air and exhaust-air dampers
  • Air filters for supply (EU7) and exhaust (EU5) air and a set of spare filters.
  • Direct-drive chamber fans.
  • Heat recovery can be obtained with two different solutions: Heat-exchanger plate (including bypass dampers) or rotary heat exchanger (including drive).
  • Water- or glycol-circulation heater or electric panel heater.


  • Cooling radiator based on water or glycol circulation or on direct evaporation.
  • Illuminated fan inspection glass.
  • Control panel.
  • Automatics with Ouman, Schneider, Siemens or Fidelix regulator
  • Connection regulators for remote monitoring (DDC).
  • Air-circulation operation.
  • Air-flow gauges
  • Mixing shunt group and water-circulation pump
  • Smoke and gas monitoring
