Hot Water \ CHW Coil

Hot water & CHW coils are suitable for low, medium & high pressure and are manufactured to almost any size using ½" or 5/8" O.D copper tubes. They are fabricated by expanding copper tube to aluminum collar spaced fins at a suitable pitch to meet key design performance parameters. These fins, which are staggered in the direction of the airflow, are mechanically bonded to deliver excellent heat transfer characteristics and are available in special materials and finishes such as copper and electro tinning to meet particular specifications.

Positioned in a rigid GI/SS section, the coil tubes are brazed to copper headers with flow and return screwed or flanged connections.

  • Tube and fin materials: Aluminum, Copper, Aluminum Clad Copper, Cupro/Nickel, and Stainless Steel
  • Rows: 1 row to 24 rows
  • Fin edges: straight edge and ripple edge
  • Fin spacing: 4 FPI to 26 FPI
  • Headers: Aluminum, Steel, Copper, Galvanized and Stainless Steel
