How it Works

Operating Principle

The I4 energy recovery wheel offers great energy recovery both in summer and winter modes. In summer times, the wheel will greatly reduce the sensible (heat) and latent (moisture) energies leading to significant cooling and dehumidification cost reductions. Following the same principle, during winter months, the wheel will recover both the heat and moisture from the return air stream and add it to the cold outdoor air for great heating and humidification savings.
