The principle of the Heat Exchanger is based on the transfer of heat by conduction. Heat needs to be transferred through a wall in order to to be able to realise heat recovery. A Plettenburg Heat Exchanger makes it possible to heat 100% fresh outside air. This results in an optimal shed climate.
The fresh outside air is heated by exhausted shed air. As a result, the highest efficiency in heat recovery can be achieved. The fresh outside air passes through an ingenious package of tubes and is heated by the exhausted warm shed air in either cross flow or counter flow. The result: conditioned fresh outside air supplied with a temperature approximately equal to the inside shed air temperature and a low humidity leading to maximum dry capacity. Humid shed air, containing, CO2 en NH3, is not reused this way!!
