How to
optimize your buffer tank

Customized, efficient and economical – medium-high finned tubes in
carbon steel

Would you like to optimize your buffer tank? Then you have come to the right place!

Our proven medium-high finned GEWA-D tubes are now also available in carbon steel and therefore represent an interesting alternative to high-priced materials – and this with the same or higher efficiency! Regardless of whether it is an application in the solar, heat pump or heat recovery sector.

The high heat transfer due to the large outer surface allows for a compact design compared to smooth tube heat exchangers. The energy capacity of your tank can be increased by 25% related to dynamic loading cycles and unloading cycles.

These robust and customized heat exchangers can be welded directly into your steel tank. There are no additional costs for fittings or other connection technology.

The innovative finned tube solution in carbon steel can also be used in many other applications such as solid-fuel boilers and help you to build your equipment more efficiently and economically. Wherever heat has to be transferred cost-effectively, the GEWA-D tube in carbon steel is your solution.
