What is a Low Finned Tube?

A Low Finned Tube is a heat transfer enhancement tube formed from an integral, low-height fin extruded directly from the outer tube wall. The fins provide additional external surface area which is used to enhance the thermal performance of condensers, heat exchangers, boilers, air coolers and refrigeration systems. These Lowfin Tube, Trufin Tube, Integral Fin Tubes aid industry by decreasing energy usage while maximizing the efficiency of their equipment.

Low Finned Tube Manufacturer & Supplier in India

One of the premier Manufacturers, Suppliers and Exporters of High Quality Low Finned Tube for challenging heat transfer applications. It has been fabricated using modern finning technology, offering superior thermal efficiency, mechanical strength and longevity.

We are a reputed Low Alloy Steel Finned Tubes Manufacturer & Exporter for the power, petrochemicals, oil and gas, HVAC, marine, food processing, pharmaceutical and chemical industries.

Low Finned Tubes are manufactured as per various international standards and can be supplied with customization of tube material, fin geometry, fin density, wall thickness and tube size based on specific project requirements.

What Are Low-Finned Tubes?

Low-Finned Tubes are enhanced surface tubes where multiple low-profile fins are formed directly from the parent tube material through a cold rolling process.

As this process causes both the fin and tube to be made from a single piece of material, the thermal resistance from fin to tube wall is eliminated; therefore maximum heat transfer performance is obtained.
