Triple 7™ Tube-Fin Heat Exchangers

Fin Density 6-22 fpi; Fin Spacing 1.2-4.2 mm; Tube Diameter 7 mm; Tube Material Cu, Al, Stainless Steel; Tube Matrix 19.05x16.51 mm

Tube-fin heat exchangers based on Lordan’s Triple 7™ pattern of 7 mm tubes provide reduced volume and weight compared to heat exchangers built with the usual 3/8” pipes.

Triple 7™ is an exceptionally high-capacity coil pattern with high airflow in one of the smallest possible tube diameters on the market today for finned coils. It is well suited for specialized applications where volume and weight can be critical. The Triple 7™'s small size and weight takes less refrigerant, making it a cost-effective and environmentally friendly choice.

Triple 7™ owes its name to its 7 mm tube length, tube diameter, equilateral tube arrangement, and optimal ratio between tube diameter and tube distance. The smaller the tube diameter, the greater number of tubes is possible in a given fin cross-section.

Equilateral tube arrangement (pitch), with equal distances between each tube and its six adjacent tubes, allows heat to travel at the shortest possible distance from fins to tube. As a result, the equilateral pitch produces the highest fin efficiency.

The high-capacity Triple 7® coil is suitable with any type of fluid and can be customized to a range of specialized heavy-duty, precision cooling or industrial cooling applications.

Finned height and length, number of rows, number of circuits, fan mount and access valve fittings, among others, are tailored to the customer’s specifications. Please contact the AMS Technologies thermal management experts to discuss your customized tube fin heat exchanger solution that exactly matches your requirements.
