See the Award-Winning New Humiditrol® Dehumidification
System at the 2008 AHR Expo, Offering Advanced Humidity Control for Split Systems

DALLAS, TX – December 13, 2007 – Winner of a 2008 AHR Innovation Award in the IAQ category, the new Humiditrol® dehumidification system for split systems provides businesses an innovative solution for improving indoor air quality. The system will be on display at the AHR Expo in New York City January 22 –24, 2008 in the Lennox International booth (number 667).

The Humiditrol dehumidification system offers space dehumidification without overcooling in one easy-to-use system. “The Humiditrol system makes it easier than ever to improve humidity control and reduce the spread of allergens,” said Jeff Hartnett, Product Manager for Commercial Split Systems. “High humidity levels, rather than room temperature, activate the dehumidification cycle to help improve indoor air quality.”

If a room or building’s humidity level exceeds the system’s setpoint, the SignatureStat™ control activates the Humiditrol system, which works with the heating and cooling system to remove excess moisture by reheating cooled air. By reducing humidity, this patented reheat design helps control the growth of mold, mildew and dust mites which have been linked to allergies and asthma.

Based on the award-winning Humiditrol dehumidification system originally developed for rooftop units, the new system is a secondary coil installed downstream of the evaporator. Now available as a field-installed accessory, the Humiditrol dehumidification system can be matched with three-phase S-Class™ and T-Class™ 3- to 5-ton R-410A commercial air conditioning or heat pump split systems.
