Steam Distributing Coils or “No-Freeze Coils”

Steam Distributing Coils or “No-Freeze Coils” Steam distributing coils are designed to minimize the potential of freezing when the coil sees air temperature below 40˚F or operates on a system with modulating steam pressure. Steam Distributing coils insert an inner tube down the entire length of the […]
