Heat Exchanger Coil

Tube size

  • 5/8" O.D. x 0.4-0.65 mm wall thickness is standard
  • 1/2" O.D. x 0.4-0.65 mm thickness is standard
  • 3/8" O.D. x 0.4-0.65 mm thickness is standard

Fin Material

  • Thickness of Aluminium fins: 0.15-0.4 mm
  • Fins spacing between two fins: 4-12 FPI
  • No. of rows available:2-12

Headers

Seamless M.S. and Copper headers, sized to minimize water pressure drop. With die-formed holes that provide a parallel surface to the coil tube for strong brazing joints

Connection / Circuits

Jawl provides different types of circuits like Quarter circuit, Full circuit, Double circuits

Testing and Performance

Hydro test
All coil assemblies are tested with water at 1700 PSI

Nitro test
All coil assemblies are tested with Nitogen filled at 300 ib/in2

Feature

Jawl makes coils that provid two or more rows that are based on counterflow of water with respect to airflow. The mechanical expansion provides an efficient bonding of copper tube and fins for better heat transfer. Tubes are staggered in the direction of airflow.
