Air-to-Air Heat Exchangers

The Air-to-Air Heat Exchangers use exhaust air to pre-condition incoming air to reduce cooling or heating demand and the overall size of the air conditioning system. This improves the energy efficiency of the building and can also help to comply with buildings regulations.

  • Nine models with air flow range 150 m3/h to 2,000 m3/h

  • Can be integrated into air conditioning systems, reduces size of overall system

  • Fresh air ventilation

  • Changes temperature and humidity of entering fresh air

  • Helps prevent sick building syndrome

  • Reclaims 20-50% of the energy lost by ventilation

  • Recovery of up to 75% heat from the outgoing air


Air conditioners and heat exchangers are controlled with the same main bus system (TCC-LINK)
