Technical details and manufacturing context for Heating/Cooling Coils
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Nominal Diameter | DN15–DN300 mm | Common range for coil connectionsISO 6708 |
| Heat Transfer Area | 0.5–50 m² | Depends on coil rows and fin spacing |
| Operating Temperature | -40–150 °C | For water/glycol; steam up to 200°C |
| Test Pressure | 1.5–2.4 MPa | 1.5× operating pressure |
| Air Pressure Drop | 50–250 Pa | At face velocity 2–3 m/s |
| Water Pressure Drop | 10–80 kPa | At water velocity 0.6–1.5 m/s |
| Face Velocity | 1.5–3.5 m/s | Higher velocity increases pressure drop |

Manufacturer profiles associated with Heating/Cooling Coils.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Common tube materials include copper, copper-nickel, and stainless steel (SS304, SS316). Fin materials are typically aluminum, copper, or stainless steel. Material selection depends on the application and corrosion requirements.
The typical operating pressure range is 1.0 to 1.6 MPa, with a test pressure of 1.5 to 2.4 MPa. These values are reference ranges and must be confirmed for the specific coil model.
Tighter fin spacing increases heat transfer efficiency but also increases air pressure drop. Fin spacing typically ranges from 1.5 to 6.0 mm, and the optimal spacing depends on the application and allowable pressure drop.
Relevant standards include ISO 6708 for nominal diameter, and ASTM B75, A312, B209, A240 for tube and fin materials. These are procurement references; verify compliance with the supplier.
