This steam 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. Blank off plates secure the coil and help maintain the proper velocity across the coil. The modular design also lends itself to easier installations since modules bolt together on location.
Uniform steam distribution to each of the coil core tubes is accomplished by proper header assembly design. The steam supply connection should be located in the center of the header, with a perforated plate type baffle located directly behind this connection. Properly sized orifices are located in each of the core tube entrances into the header.
Coils are "freeze resistant," also known as the dual-tube design. It is important to note that any steam coil can freeze when exposed to freezing temperatures without the proper drainage of the condensate. This coil design utilizes a smaller inner tube, with precisely spaced, directional, orifice type perforations. This is to help direct condensate flow to the return header.
