Profile: Rotor Source, Inc. provides desiccant dehumidification, energy recovery and evaporative cooling components to original equipment manufacturers of custom engineered & commercial/industrial HVAC systems. We offer ProFlute™ desiccant dehumidification rotors (also commonly referred to as desiccant dehumidification wheels) and cassettes. Its high capacity substrates include silica gel, hygienic rated silica gel and molecular sieve desiccants. Rotors and cassettes are available in a variety of configurations to meet specific air drying or humidity control requirements. NatureCool™ evaporative cooling pads are made from a special cellulose paper which is impregnated and treated to resist biological & mechanical degradation. The cross fluted design of the media results in two important effects. First, it optimizes the amount of surface area available to hold the water which the air flows over. And second, the angles cause the air to change directions in a way that ensures that all of the air will touch a wetted media surface before leaving the pad. Therefore, the air leaves the pad with the greatest amount of cooling and/or humidification possible. This pads also act as a natural filter that purifies the inlet air. The carefully designed flute angle directs water towards both the air inlet & outlet side, the water then intrinsically flushes away dust, algae, and mineral build up on the evaporation surfaces.
