Finned Tubes

Finned tubes – Enhanced efficiency

The thermal efficiency of a heat exchanger is detrimentally affected by corrosion and fouling. This, in turn, drives down process productivity. Experienced choice for the design of heat exchangers can make all the difference. This is why, when appropriate, we propose extended surfaces heat exchangers. In these, the fins are attached to the primary surface on one side of a two-fluid or a multi-fluid heat exchanger.


Balance budget and longevity considerations

To meet your requirements, we offer customised finned tubes. Our ability to combine any tube and fin material (e.g. copper-alloys, stainless steel, aluminium, titanium), tube and fin pitch, helps you to balance budget and longevity considerations. Whether you need new equipment or to retube a heat exchanger, we can help.

Lower maintenance costs & reduced energy consumption

Our expertise in the use of vortex clean air technology reduces pressure loss and fin fouling. This means lower maintenance costs and reduced energy consumption.

Type of fins

Our extended-surface heat exchangers use the following fins.

  • Patented Elfin finned tube
  • LL-fin
  • T-fin
  • NEL fin
  • Gilled fin
  • Spiral and helical wound finned tube
  • HEI fin.

Elfin technology success story – Class leading levels of performance and durability

We re-tubed three air blast (fin fan) units for a chemical production plant in the North of England. The units were in poor condition because of the corrosion, the damage from atmospheric deposits and the consequent maintenance (low pressure water) cleaning.

Sterling Thermal Technology was chosen for our unique Elfin technology. We supplied new Elfin cores matching the material specification but an alternative fin construction to traditional wire wound fin, superior for its quality and longevity.

Our customer reported our supplied units were performing very well and were highly effective. So much that they were compensating for underperforming existing heat exchangers in the same system eliminating the immediate need to replace these older units.

Most importantly, the issues caused by the damage from habitual cleaning in the removal of fouling were minimised because of the integrity of the Elfin block. The Elfin block can be cleaned by high pressure water cleaning, unlike other fin types.
