Passive Dehumidification Rotors

Dependable Passive Rotors

Rotor Source’s passive dehumidification rotors – commonly referred to as passive dehumidification wheels or Cromer wheels – and cassettes are made of high-capacity substrates (including silica gel desiccants). Our rotors and cassettes are available in a variety of structures to fulfill your air-drying and humidity-control requirements.

In addition, our recore program has gained notoriety as a faster, more cost-effective method of replacing any brand of passive dehumidification rotor product.
