Hot Water Coil

Hot water coil is similar to Chilled Water Coil but it uses hot water as a medium. It is made from row of tubes which pass through stacks of formed fins. It is widely use in food industrials for food processing to control Relative Humidity (RH) and timber or wood related industrial as a dryer.

The temperature of hot water in Hot Water Coil is ranging from 40°C to 80°C. Hot water coil is usually installed in front of Chilled Water coil in an AHU for the purpose of controlling supply air RH. As cold air passes across hot water coil and contact with it surface area, heat will transfer from the flowing hot water in tubes to fins and finally to the cold air.

Provides high-efficiency and good quality finned coil, which made of copper tube mechanically bonded to aluminum or copper fins. We are committed to the design, manufacture and supply of world competitive products and services that provide the best customer value for both local and export markets.  Thermal-Matic aims to become an absolutely reliable custom made coil manufacturer, providing total solution to your requirement and needs in Air-Conditioning, Refrigeration line, Marine, Offshore coil, Bus/Truck, Commercial/Industrial condensers, evaporators and etc.


Fins are fabricated from either Aluminium or Copper with extruded collars to maximize heat transfer and ensure accurate fin spacing. Fin surfaces are available in corrugated, sine wave or enhanced with enhanced with edges that are straight or rippled. Special chemical coating for marine enhance application is available upon request. Spacing available from 3 FPI to 20 FPI (Fin Per Inch).

Seamless drawn copper tubes are available in 3/8″Ø, 1/2″Ø & 5/8″Ø. Grooved tubes are available on request.

Standard casing with galvanized steel.  For better resistance to prevent corrosive is by using Stainless Steel – 304 (2B) or 316L (2B) on request.

Header is fabricated from copper, galvanized steel and schedule 40 (Steam Pipe).

All coils are 100% leak tested under water using high pressure dry air 350-400 PSIG.
