- Transfers both sensible and (if enthalpic) latent heat between supply and exhaust air. Goal: cut HVAC heating/cooling load. Made of aluminum or polymer matrix, sometimes with a moisture-absorbing coating.
- Impregnated or coated with a desiccant (silica gel, molecular sieve, or zeolite). Its job is dehumidification - it pulls moisture from the process air into a hot reactivation airstream. It actively dries air rather than just exchanging energy.
- An energy wheel conserves energy between two building airstreams. A desiccant wheel removes moisture using an external heat source (often exhaust or gas heat).
- Need deep drying (low dew point) for storage, pharmaceuticals, or comfort in very humid climates. Cooling coils alone can't reach the required humidity without overcooling.
- Goal is simply to lower heating/cooling energy; see our troubleshooting guide for upkeep. Pair with a climate-based selection.
- Many systems combine both: a desiccant wheel for drying plus an energy wheel for the remaining load. For strict separation needs, a plate exchanger avoids any carryover.
