Achieving Comfort and Energy Savings

The total heat exchange rotor recovers thermal energy. Furthermore, the dehumidifier rotor performs dehumidification.
This reduces the energy the air conditioning equipment requires, contributing to overall building energy efficiency.

By lowering indoor humidity, comfort within the indoor space is improved even at the same temperature.
