Heat Recovery UNIT

The BOREAS Fresh Air Unit with Heat Recovery (HR) was designed to achieve high indoor air quality while saving energy in air conditioned spaces.

The plate type heat recovery exchanger which is the main component of BOREAS HRU was selected to provide the maximum heat transfer performance in residences, offices, schools, and industrial areas.

It is a user friendly product which offers convenience during assembly, operation, and control.



Energy efficient, fans driven by 3 speed motors with a low noise level

High efficiency, counter flow, aluminum plate type heat recovery exchanger

High indoor air quality with accessible and easily removable and cleanable filters

Insulating layer providing sound and heat insulation in internal surfaces

In addition to saving energy, Teknoklima Heat Recovery Unit (HR) was designed to achieve high indoor air quality in air conditioned spaces. Plate type heat exchangers used in HR units provide major conveniences and a wide range of application in residences, commercial, and industrial air conditioning and ventilation applications. Exchangers with high conductivity and high performance ensure efficient heat transfer between warm and cool air currents.

All inputs and outputs can be configured independently of each other.

Standard ModBus communication unit enables secure communication up to 100 m between the control card and room unit.

Other Functions

  • Weekly timer
  • BMS addresses can be assigned over the display.
  • The means to program indoor air quality and CO2 scenarios
  • RS485 interface
  • Modbus RTU


Electrical Heater

Electrical heaters are used as freeze prevention measures on fresh air intakes in very cold climates or to increase air temperature after heat recovery in the winter in temperate climate conditions. They are manufactured of stainless steel material and safety measures are taken with a safety thermostat and pressurestat.



Water Heater

Electrical heaters are used as freeze prevention measures on fresh air intakes in very cold climates or to increase air temperature after heat recovery in the winter in temperate climate conditions.



Water Cooler

Water coolers are used to reduce air temperature after heat recovery during summer in warm climate conditions.



DX Cooler

Water coolers are used to reduce air temperature after heat recovery during summer in warm climate conditions. They are connected to outdoor VRF units, enabling them to serve as indoor units.
