Wound Tube Dealers in Mumbai

We are one of the largest Wire Wound Fin Tube Manufacturers in India . Wire Wound Fin Tube is our star product becauseof its superior efficiency. It consists of wire loops wound that are Solder bonded to the external surface of a round tube.The variable density of wire loops allows for optimal thermal selection. With our flexible manufacturing process these tubeare now very cost effective for both small and large volume applications.

• Application: Applied to the Air Conditioner, the Assembly Type Air Conditioning Unit, Refrigerator, Freezer, Chest, etc.
• Specification: O.D: 3/16" to 3/4" (4.76 to 19.05 mm)
• Coil Weight: 100-400 Kg

The Level Wound Coil (LWC) Copper Tubes is one of our imported & supplied products. All LWC tubes are normally produced according to ASTM & Coproclima specifications. These specifications were prepared to take account of the requirements of ACR industry.   Each millimetre of tubes is 100% Eddy-Current tested and any surface defects found will be clearly marked by black colour.   For heavy coils, we wound LWC copper tubes in "Eye to Sky" (Jumbo) form as per customer request.   The tube is cleaned with Nitrogen purging. Moreover to protect the tubes against dust & internal oxidation during transportation or long storing, the tube ends are sealed with plastic caps.    Sunflex Metal Industries deliver LWC with cardboard reels. Coils on reel are stacked on wooden pallets and shrink wrapped. Level Wound Coils are specially suited to long production runs for industrial applications and it is widely applied to the Air Conditioning & Refrigeration as well as the Heat Exchanger field.   Most commonly supplied in the soft and light annealed form, also Level Wound Coils can be ordered in hard drawn temper.

• Thickness: 0.28 to 1.0 mm
• Application: Evaporator coils, Component for AC & R, Condenser Coils, Heat Exchangers
• Range: OD 4.76 TO 19.05 mm

These tubes are manufactured using wire in place of strip and wound helically over the tube with root soldering at foot to avoid air gaps between fin and the tube resulting in to higher heat transfer efficiency, reliability and longer service tube.

The method of attaching the fins over tube is of prime importance, since even a slightest air gap between the tube and fins will defeat the whole purpose of fins over the tube.Considering the above facts Heft has indigenously designed and developed a special purpose tube fining machine capable of producing following types of finned tubes.WOUND FINNED HEAT EXCHANGERS tubing used in the maintenance and manufacture of the air cooled heat exchangers, air heaters & other related heat exchangers.

We are dealing in wire wound fin tubes, 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.

unraj Industries 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.Wire wounded tubes can be manufactured by using various base tube material such as Carbon Steel, Copper, Cupro—Nickel, Brass and Alu. / Adm.
