With single-tube coils, the steam supply and condensate return headers and connections are normally at the opposite ends of the coil. Uniform steam distribution to each of the coil core tubes is accomplished through careful 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. Carefully sized orifices are located in each of the core tube entrances into the header.
Dual-tube coils utilise a smaller inner tube, with precisely spaced, directional, orifice-type perforations. This helps to direct condensate flow to the return header. The steam supply, condensate-return headers, and connections may be fabricated in 'same-end' or 'opposite-end' orientation.
Steam Coil Application
• Commercial and industrial heating systems
• Commercial and industrial drying and processing applications
Steam Coil Specifications
• Copper nickel
• Carbon steel
• Stainless steel
Additional fin material available upon request.
Standard or steam distributing construction is available for high and low pressure applications. Standard steam type is 5/8" or 1" tube steam coil, known as the single-tube design.
Any steam coil can freeze when exposed to sub-zero temperatures without the proper drainage of the condensate. Steam-distributing 5/8" and 1" tubes are "freeze resistant", known as the dual-tube design.
