Double Rotor Setup
The supply air must be cooled and dehumidified in regions with high air temperature and humidity. The double rotor concept is cooling, dehumidifying, and heating the supply air more energy effectively.Both our Models E and ES work perfectly for a double rotor setup. You’ll need one enthalpy/adsorption rotor and one sensible rotor.

This is how the double-rotor setup works.
1. The enthalpy/adsorption rotor dehumidifies and cools the hot and humid outside air.
2. The cooling coil dehumidifies the outside air until the requested humidity level is reached.
3. The sensible rotor reheats the outside air to the required supply air temperature.
4. At the same time, the exhaust air is cooled, which increases the efficiency of the enthalpy/adsorption rotor.
Setup and Psychrometric Chart
The double-rotor concept is an energy-efficient solution for cooling and dehumidifying outdoor air for comfort ventilation applications. It utilizes highly efficient rotating heat exchangers with up to 90% humidity efficiency, eliminating the need for less or no reheating.
