New Bypass and Powered Humidifiers

Johnson Controls Adds New Bypass and Powered Humidifiers to its Line
Of York® Home Comfort Products
Humidifiers offer easy installation and high evaporative capacities

NORMAN, OKLA. - (March 14, 2008) - Johnson Controls is adding three new humidifiers to its line of York® home comfort products. This includes small and large bypass humidifiers and a high-capacity, fan-powered humidifier - units for virtually any home with a forced air system.

York humidifiers provide humidity in the form of pure water vapor to prevent minerals from entering the air stream. Water is supplied to a distribution tray and flows evenly across a water panel. Heat from the heating system causes the water to evaporate. Properly humidified air (vapor) is then distributed throughout the entire home. During operation, a constant flushing action occurs which sends mineral leftover from evaporation to a drain at the bottom of each humidifier. This flushing action keeps the unit operating efficiently while keeping maintenance to a minimum, typically once a year. Maintenance is fast and simple and includes cleaning the water distribution system, replacing the water panel and flushing the drain line.

The actual amount of humidity that should be introduced into the home during the winter changes as outdoor temperatures change. Too much humidity in the home when it's very cold can cause window condensation and potentially damage the structure of the home. The optional York automatic humidifier control continually monitors and responds to outdoor temperatures by receiving signals from an outdoor sensor more than 400,000 times per day. This insures optimum levels of humidity throughout the home as outdoor temperature changes occur. Homeowners never have to monitor or change humidity settings or wait until they feel uncomfortable. The automatic set-it-and-forget-it control keeps their home's humidity level exactly where it should be. The control is totally solid state and designed for many years of trouble-free operation.

York whole-home humidifiers are installed out of the living space as part of the heating system, providing quiet operation. Due to their fully automatic operation, there are no messy reservoirs to fill and clean, and frequent maintenance is not required. They humidify the entire home, not just one area as is typical of less efficient portable units.

Both the large and small bypass humidifiers mount easily on the supply plenum or return duct and require a ½-inch drain connection and a minimum static pressure of .2” w.c. to create air flow for evaporation. The units include a manual humidistat, saddle valve and a 24-volt step down transformer, and a scientifically designed water distribution tray keeps water flowing evenly over the water panel for maximum evaporation. The units also offer fast and easy left-right bypass conversion with their reversible housings, nameplate and drain spud/plug features.

York® products from Johnson Controls, Inc., include energy-efficient, residential central air-conditioners, heat pumps, furnaces and accessories and innovative light-commercial, packaged heating and cooling systems marketed through a national distribution network and delivered to home- and building-owners through qualified York heating and cooling dealers.
