| New Products > Triple 7: Today's High-Capacity Coil Pattern
| |
 |
|
 |
LORDAN has developed an advanced coil pattern that provides a higher capacity than
any other coil pattern currently on the market. The Triple-7 coil pattern owes
its exceptional merits to the combination of two properties.
|
|
|
 |
|
 |
7 mm tubes, presently the smallest tube diameter available
|
|
 |
|
|
|
Equilateral tube arrangement creates equal distances between each tube and its six adjacent tubes
|
|
 |
|
Smaller tube diameter and smaller distances between the tubes results in more tubes per fin cross section and
means more primary surface area. The combination of tube diameter and equilateral tube arrangement is
responsible for the higher capacity of the Triple-7 coil pattern.

THE ADVANTAGES OF TRIPLE-7 COIL DESIGN |
 |
|
|
 |
|
|
The smallest diameter tube coil provides the highest capacity.*
|
|
Smaller tube diameter and tube pitch coils have larger tube surface and provide more capacity.
|
|
*Capacities are for 0.05 m2 evaporators with the same fin depth, operating with the same fan.
|
|
The highest capacity 7 mm tube coil is the Triple-7, which has equilateral tube pitch.*
|
|
For the same coil size, tube diameter and number of tubes, the equilateral tube pitch has
the highest capacity for two different reasons:
|
|
 |
It has the highest fin efficiency. |
|
It has the lowest resistance to airflow, resulting in increased airflow and greater capacity. |

TRIPLE-7 SPECIAL APPLICATIONS
|
|
Automotive
|
|
Buses
|
|
Marine condensers and evaporators
|
|
Industrial high-tech applications
|
|
Ceiling induction coolers and heaters
|
|
Circular coils
|
|
|
|
Triple-7 coils are well suited for condensers, evaporators, and heater/cooler coils. (Heater/cooler coils are compatible with any type of fluid.)
LORDAN can produce coils as small as 5 cm or as large as 3 m. In almost all cases, Triple-7 provides higher capacity or takes less
space than any other coil pattern.
