Advantages of Active Desiccant in Surgical Suite Conditioning

DS Unit

Active desiccant dehumidification can provide energy and operational savings and at the same time cooler, drier conditions in Surgical Suites over typical cool-reheat dehumidification methods. This is possible because of the small space loads in comparison to the high air change rates needed, generally 20 ACH.


Active desiccant dehumidification units do not require low temperature glycol or refrigerant systems to remove humidity from the air. Standard 45F chilled water can be used to achieve space dew point conditions of 40F and lower if desired.

Surgical Suite Personnel

Active desiccant dehumidification Dry Surgery DOAS systems can make existing air handling systems achieve new, lower temperature and humidity requirements to reduce Hospital-Acquired Infections. As low as 50⁰F/50%RH, more typically 62⁰F/50%RH.

Is it "Raining" in Your Surgery Suite?

Surgical Suite

Is it "raining" in your operating rooms? Do you find that there are times throughout the year when humidity levels are so high that droplets of condensation are dripping from the ceiling diffusers and suspended fixtures of your surgery suites? This is a common complaint being heard frequently in hospitals today and this article is an effort to give readers an understanding of the cause of this moisture/humidity phenomenon. By understanding the cause of the "rain" and the probable cause of higher than desired relative humidity levels, these problems can be resolved and/or prevented from occurring in your operating suite.
