Hello,
We are trying to find a company that can build a desiccant dehumidifier that works on 70 DegC waste heat from our industrial processes. The principle is that if we dry the fresh air before it enters the cooling coil of our air-handling units, we would save energy because a large part of the cooling required to remove the moisture from the fresh air will be saved. The equipment will employ three circuits.
1. The fresh air being pulled by the AHUs passes through a filter and a desiccant wheel. It loses moisture and increases in temperature. This air then passes through an air to air heat exchanger to reduce its temperature again.
2. The other side of this heat exchanger uses ambient air that passes through a filter, and an adiabatic humidifier to cool down by evaporation. It then moves through the heat exchanger from where it is exhausted. The adiabatic humidifier can consist of both fogger and fan combined in one unit.
3. The desiccant wheel is regenerated by a flow of hot air coming from our processes.
We have found several suppliers of individual items, but hardly anyone who can design and build the whole system. if you know a company kindly let us know. Thanks.
