Low-finned tubes for refrigeration technology

: Low-finned GEWA K and GEWA KS tube; Low-finned GEWA K and GEWA KS tube

GEWA-K and GEWA-KS

For refrigerant condensers and evaporators a large heat transfer surface and at the same time compact system size is of fundamental importance. In this way you maximise the heat transfer capacity and minimise the overall costs. You can achieve this by using low-finned Wieland GEWA-K und GEWA-KS tubes.

The advantages in comparison with smooth tube solutions

Great variety of dimensions
Considerable savings potential due to the reduction of the tube length required for the capacity
Option of compact, light and economical design of shell and tube heatexchangers
Reduction of refrigerant charge
