Engineered Systems - February 2009 - (Page 30) Humidification In Health Care on an outdoor temperature limit is not enough. So in conclusion, some humidity control in these critical environments is important, but a lot of flexibility is allowed to help the building owners and operators cope with issues like steam quality, controllability, operating cost, and energy usage. Keep it to the minimum, keep it as simple as possible, and use high-quality control elements in order to enjoy an acceptable environment in your critical spaces.

Input 49 at www.esmagazine.com/instantproductinfo Matches AC System Output to Changing Loads, Maintains Comfortable Humidity Levels Most AC systems lack subtlety: they either run at full capacity or they’re off. Under low load conditions, most systems quickly cool the air and then shut down, allowing humidity to build. The APR Control lets AC systems operate at less than full capacity so they continue to dehumidify without overcooling. ■ For retrofits or new DX systems to 100 tons ■ Ideal for makeup air and VAV systems ■ Fast, simple installation RAWAL DEVICES, INC TEL : 800 727 6447 FAX: 781 933 3306 sales @ rawal.com www.rawal.com Input 135 at www.esmagazine.com/instantproductinfo 30 En gi neer ed S y stem s February 2009 Input 16 at www.esmagazine.com/instantproductinfo http://www.shortridge.com http://www.esmagazine.com/instantproductinfo http://www.parkerboiler.com http://www.rawal.com http://www.rawal.com http://www.parkerboiler.com http://www.esmagazine.com/instantproductinfo http://www.esmagazine.com/instantproductinfo
