Wire Turbulators for Heat Exchanger Tubes

Midland Wire Cordage Co. Ltd. has been manufacturing Turbulators since 1968 and has considerable experience and expertise in this complex field. The turbulators offered by MWC are manufactured from wire in the form of a looped spiral as the photograph / illustration shows. This looped spiral design, we believe, has many advantages over the fin or spiral sheet metal types. These can be detailed as follows:-

1. The density of the turbulator can be infinitely varied to suit the liquid or gas flowing through the tube to promote maximum turbulence and heat transfer coefficient with a minimum loss of pressure. This enables the designer to economise on the length, diameter and number of tubes required in each installation and allows flow pump sizes to be downsized. Right:
3/4 x 18 gauge for air coolers

2. MWC turbulators are manufactured with a small eye at one end to assist the pulling into the tube and a tail is left on the opposite end to allow joining when tubes over 3 metres are involved. We can of course modify these standard designs should customers requirements justify non-standard developments. Right:
1" x 18 gauge stainless steel insert

3. MWC turbulators are manufactured to grip tightly to the inner wall of the tubes and with normal flows of liquid or gas will require no fixing. This also allows the added flexibility of easy removal where tubeside cleaning and maintenance are economic considerations. However, should the customer require the ideal compromise between ultimate heat transfer performance and fluid pressure drop then the turbulator can be bonded inside the tube. Right:
500 loops per foot can also be produced from 96 loops per foot to 500

4. Current production turbulators are manufactured from zinc coated carbon steel, stainless steel and copper wires but should you require any other metal we will consider the possibilities. Right:
Insert to fit 22.95 mm or 1" 18 Gauge tube for air cooler 276 loops per foot

5. Our manufacturing capability allows lengths from 30 cm - 5 metres to be accommodated easily with the option of joining far longer lengths and for inside tube diameters from 8 mm - 38mm. Special orders for sizes outside of this range can also be considered. Right:
3/8 x 22 gauge galvanised insert 225 loops per foot
