Calorex HRD systems

The Heat Recovery Dehumidification (HRD) is a hybrid fresh air dehumidification system with dynamic heat pump heat recovery to swimming pool water and air. The unit will provide the complete answer to humidity control, water/air temperature control and real time fresh air requirements.

By recovering the latent energy in the moisture laden air of a pool hall, your HRD will return this energy to heat the pool water or use it to assist with pool air heating. Furthermore, there is usually sufficient recovered energy to provide all the operational water heating requirements with any further surplus used for air heating.
