Product Description

WIRE WOUND FINNED TUBES

These finned tubes have fins made of wire instead of strips. Continuous loops of wire are formed and are continuously soldered to the circumference of the tube to ensure 100% contact. Loops per turn and turns per foot can be altered as per surface area requirements. Due to continuous soldering of wire loops these finned tubes offer a very high heat transfer efficiency with less air pressure drop. Used in air cooled Oil Coolers in thermo Pac units and also used for Air Heating applications.

We also supply bare tubes with Flexible turbulator / inserts inside which are continuously soldered with the inside surface of the tube. These tubes can then be used for further finning by the Customers. This gives maximum turbulation with minimum pressure drop and has proved very effective for charge air coolers and Oil coolers. And gives excellent turbulation but has a higher pressure drop than the flexible type turbulator making it ideal for cooling oils which has low viscosity when hot and flow needs to be slower.

Wire wound finned tubes are commonly used in applications with metal temperatures up to 180 degrees C.
