OVAL TUBE TECHNOLOGY

Maximum efficiency, low power consumption.

Oval Tube is a Refrion exclusive. The oval shape of the tubes, inserted in our Dry Cooler batteries, reduces friction and the resultant loss in air pressure. This means more air, less stress on the fans, less noise and improved yield.
The revolutionary 31SO geometry with oval tubes is the real innovation in the production of heat exchangers.
The 31SO geometry enhances performances up to 15% compared to the round tube geometries. Air-side pressure drops can be reduced by 40%, allowing a better performance of the axial fans. All this leads to a quieter operation and a lower energy consumption.
The series of Coolers that use the oval tube are distinguished by the coil type code E.
