Thermal-Matic Chilled Water Coil
The chilled water temperature from a chiller unit pumps to CWC is around 7°C and leaving it at 12°C. The water is circulating between chiller and CWC. There is some time by requirement, CWC is used for lower temperature application. If the temperature is less than 0°C, chilled water has to be mixed with a chemical named Glycol. The fin pitch of CWC has to be increase to avoid freezing. Thermal-Matic will provide suggestion on the fin pitch when we design the coil.

Components
Fins
Fins are fabricated from either aluminum 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 edges that are straight rippled. Special chemical coating for marine enhance application is available upon request. Spacing 3 FPI to 18 FPI.

Tubes
Seamless drawn copper tubes are available in 3/8″, ll2″ & 5/8″ Dia. Grooved tubes are available on request.

Casing
Standard casing with galvanized steel. For better resistance to corrosive by using stainless steel 304-28 or 3l6L-28 on request.

Headers
Headers are fabricated from copper, galvanized steel & schedule 40.

Ibsting
All coils are lO\Vo leak tested under water using high pressure dry air 350-400psing.
