Triple 7 -
The Equilateral Advantage
Since 1958 Lordan has been specializing in designing fin and tube coils for the HVAC&R markets.
The Triple 7 was developed and introduced to the market in response to evolving demands of the high technology sectors and in the midst of changing regulations and standards growing out of environmental concerns.

The 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.
About the Triple 7
It owes its name to its 7mm tube length, tube diameter, equilateral tube arrangement, and optimal ratio between tube diameter and tube distance.

The smaller the tube diameter, the greater amount of tubes in a fin cross-section.

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