Air to Air Plate Heat Exchangers

Air to Air Plate Heat Exchangers, or Air Plates as they are also known, are an extremely effective and low-cost way of reducing the heating or cooling loads on the treatment of process air and air conditioning/Ventilation systems. A reduced heating or cooling load means lower energy bills and lower carbon emissions. Air Plates Heat Exchangers use the exhaust air to pre-heat or pre-cool the in-coming supply air, without the two air streams ever mixing.

Applications
- Heat recovery from flue stacks, ovens extracts and process areas, to pre-heat incoming air for process heating and drying applications
- Heat recovery from exhaust air for space heating for factories, offices and warehouses
- Pre-cooling of incoming air for air-conditioning units using exhaust cool air
- De-humidification or humidification of air streams

Efficiency
- Energy recovery can be as high as 70%, depending upon operating conditions.

Plate Types
- Corrugated plate surfaces, for high efficiency and energy recovery
- Smooth surface plates that can be easily cleaned for dirty air streams

Materials
- Aluminium – non-corrosive air streams. Max. temperature 200 °C
- Epoxy coated aluminium – adds protection to the aluminium for air streams containing salts etc.
- Mild steel – high temperature,  dry non corrosive air streams. Maximum temperature 500 °C
- Stainless steel – moist or corrosive air streams. Maximum temperature 500 °C
