This Modular Chilled Water Coil housing has been designed so that there is easy access to either side of the coil. Over sized doors offer plenty of room through which to clean and maintain the coil from either side of the housing. Blank off plates secure the coil and help maintain velocity across the coil. Modular design also lends its self to easier installations since modules bolt together on location. Cooling applications are most commonly used in hot fluid systems for comfort conditioning of a forced air stream and in process systems for drying processes. The collector header design with internal baffles provides circuiting flexibility while eliminating the need for return bends, while the splayed header design uses return bends for circuiting in lieu of a collection header. The term "splayed" means that the coil headers are offset outward from the coil tubes. The splayed header coil always has same end connections.
