Wire Wound Fin Tubes

Wire Wound Fin Tubes

Tipo Heat Exchangers Exports wire wound Fin Tubes or Turbulators made of loops of wire wound helically on a central rod or tube and soldered to the inner surface of the tube. The internal turbulators are made of stainless steels, copper and galvanized steel wire. Sunraj make wire wound turbulators for tubes of inner diameter as low as 8 mm. There being no limit on higher diameters and lengths.

Wire wound turbulators are excellent tube heat transfer enhancement devices that increase the tube side heat transfer coefficient several fold at not too high pressure losses. Wire wound fin tubes for use in air cooled oil coolers are provided with internal fins selected from wide variations in configuration. We also manufacture double pipe wire wound fin tubes for use in refrigerated air dryers and heat exchangers for viscous and small streams.

Wire wound fin tubes can withstand temperature up to 180ºC with standard solder wire. However for high temperature application it can withstand temperature up to 290ºC. This is with the use of special silver content solder wire.

Applications of Wire Wound Finned Tubes:

They are most suitable for Oil Cooler / Diesel Cooler as well as Charge Air Cooler.
They are also used in Heating / Cooling of High pressure Water & Steam, Process   liquid & Gases.

Advantages:

1. Compact design.
2. Lower overall airside pressure drop and hence lower power consumption.
3. Customizable fin density and height as per design requirements.

Can be offered in:

Tube material: CS, SS 316, 304, copper, Cupronickel, Aluminium brass.
Fin material: CS, Stainless Steel 304/316 or copper.
Tube outer diameter: 3/8″, ½”, 5/8″, ¾” & 1″
Fin height: Maximum 13 mm.

Limitations:

Is designed for 180 degrees or 280 Centigrade maximum temperature use, depending on type of solder used. As Aluminium does not solder well, the tube or fin cannot be aluminium.

These are especially suitable for:

a) Steam air heating applications. This is because the wire fins having a high airside coefficient are able to best utilize the very high coefficient of condensing steam.

b) Water Heaters – Coolers once again the high coefficient is useful.

c) Oil coolers. Here to realize their full potential, they must be used together with turbulators produced by our Turbulator division.

d) Compact high strength but light weight heat exchangers to be used with equipment like Hydraulic Oil coolers, Lube Oil Coolers and assorted Oil and Water Coolers.
