DX COIL Module
The DX coil housing has been designed so that there is easy access to either side of the coil. Oversized doors offer plenty of room through which to clean and maintain the coil from either side of the housing. The coil sits over a fully welded stainless steel drip pan that has been sloped so that it continually drains. Blank off plates and an air distribution screen maintain proper velocities throughout the housing. The modular design all so lends its self to easier installations since modules bolt together on location. Single and dual circuits allow precise capacity control. Unique interlaced circuiting assures uniform refrigerant distribution over the entire face area of the coil. Wide fin spacing availability reduces the affect of frost build up in low temperature applications. For use in central systems or duct application.
Dx Cooling should be used in areas of high humidity. Dx cooling is ideally suitable for use in restaurants, hospitals, nursing homes, hotels, schools, airports and many other similar facilities.
- Easy access to both sides of the coil making maintenance on the coil easier.
- Fully removable access doors on both sides of the housing.

Notes: Choose the COOLING THERMOSTAT AND RELAY option on heated mua units to provide condensing unit start contacts. Choose the EG electric pre-wire option with one non-heated supply fan to provide condensing unit start contacts. A capillary bulb adjustable thermostat is provided in the pre-wire with a 20' capillary tube to sense supply temperature. The pre-wire should be located within 20' of the supply duct to achieve this.
