What is an HR module?
The HR module allows some of the waste heat in the regeneration outlet to be used to preheat the incoming regeneration air. By using some of the waste heat on the outlet to preheat the inlet, the electrical heaters of the dehumidifier only pulls less power to heat to the desired temperature. This increases the overall efficiency of the dehumidifier. Increased energy efficiency lowers the operation cost of the system. Most often, the payback time of such heat recovery system will be very feasible. Contact your local reseller for more.
