Axial fan ExVENT Reco

coolingventilationexplosion-proof

If flammable gases or liquids can be released inside a housing, a technical ventilation system must dilute them with clean air to such an extent that the lower explosion limit is not exceeded. However, if there are large temperature differences between the inside of the enclosure and the environment, the air exchange causes a high energy loss. ExVENT Reco reduces the energy consumption for heating or cooling the inside of the enclosure by means of heat recovery while providing explosion-proof ventilation. The system consists of a control unit and two ExVENT Reco units, which are installed in the walls on opposite sides to ensure better flushing. A recuperator in each unit keeps the temperature inside the enclosure largely constant despite a 10-fold air exchange, resulting in an energy recovery of up to 80%.
