Leonardo DRS – Marlo Heat Transfer Solutions offers the “D” and “H” distributing steam coils. “D” coils are standard steam coils with distributing steam tubes within 5/8” condensate return tubes. These are sometimes referred to as Freeze Proof coils due to their resistance to freezing when used in temperatures below 32F. “H” coils are built the same way, except they use 1” condensate return tubes.
