Non Freeze Steam Distributing Coils for Modulating Steam Applications
The naming itself puts clear explanation of the product – non freeze steam distributing coils. If a system has a modulating steam pressure, this coil reduces the potential of freezing for the specific applications. The original design was conceptualized to provide even steam distribution so as to avoid cold spots or dead spots that have the potential of freezing.
Production of steam distributing coils has regained its spirit and demands have increased over the years. While modulation of steam pressure remains a core function in several applications, preventing cold spots or dead spots is what expected from steam distributing coils. Also, when air temperature goes below 40˚F, these coils minimize the freezing potential.
You can find manufacturers of non freeze steam distributing coils for high & low pressure applications. The tube-within-a-tube design becomes a major highlight of these coils to handle/manage steam under modulation or below 40˚F air temperature. Typical applications include duct heaters, gas heaters, boosters, reheat, preheat, etc.
