Next Operating Rooms - Benefits Modern operating rooms are cold. People working in the OR become uncomfortable because their normal perspiration is blocked by high humidity and by their protective garments. Desiccant systems can dry air very deeply, no matter how low the temperature.
Hospitals add desiccant systems at the make-up air inlet to remove the moisture load.
Without that moisture, the cooling systems can be reset for optimal temperature control, while the desiccant system takes care of controlling humidity. Each technology is used for what it does best, so while the HVAC system is operating at maximum efficiency, the surgical staff can work in complete comfort. The Surgeon feels comfortable in spite of heavy radiant heat from lights and equipment, and continues to work with less stress and therefore less potential for error. In Ductwork Dry air from the desiccant system floods the air distribution system, starving any mold and mildew that might otherwise grow in air ducts and on filters. Dry air increases the safety margin protecting patients from airborne fungal infections.
