Increase in production capacity and lower energy costs
An inspection of the cross-flow heat exchangers of the heat-recovery system after 12 months of operation has shown that there is no caking of pollutants. Therefore no special cleaning is necessary. Only the outside air filter needs to be cleaned from time to time to prevent pollen and dust from the outside air from entering the production building.
The energy saving concept was checked and supervised by an energy consultant EnergiePunkt UG, Hildesheim/Germany. The confirmation by an accredited energy consultant is required in order to receive a subsidy from the KfW Bank for the total costs of the heat-recovery system. This ensures that only sensible heat-recovery concepts benefit from EU subsidies for CO2 avoidance.
