Overview
Trinity Enterprises are specialists in 'TEFIN' Rectangular finned tubes. With the TEFIN computer-generated technology, each fin strip is mechanically forced over the outside of tube, producing a tight and thermally efficient bond. This process ensures, not only excellent adhesion of the fin to the tube, but the vital inner tube wall is not compromised in any way.
The TEFIN fins have been precision punched to leave an 'L' shaped lip that ensures exact fin pitch spacing between fins.
The computerized punch process can adjust the tube pitch minutely to 0.01mm tolerance to conform with the exacting computer calculations. TEFIN finned tubes are produced in blocks which are custom sized to fit the exact duty requirements and dimensions of the heat exchanger.
TEFIN technology allows tubes of any wall thickness and material to be used and ensures the inner surface of the tube is not compromised and the strength of both the tubes and the fins is enhanced.
Advantages of Rectangular Fins Tubes
Higher heat transfer area thus enhancing rate of heat transfer.
Reduced size of heater for the same application.
Air flow distribution uniform across entire heat transfer area.
The contact between fins and tubes is a firm contact and does not give away with time like crimped or wire wound fins.
Very less chance of dust accumulation on account of simple construction of fins, compared to other type of fins, which have too many crevices on account of the construction.
Easy cleanability, washability of the fins surfaces.
