Wieland WRW

Finned Tube Heat Exchanger for heating liquids

Wieland WRW series heat exchangers are helical coils made with medium-high finned copper tube and brazed connection out of brass.

The standard galvanic tin-plated outside surface reduces the corrosion risk of galvanized steel pipes connected downstream.

Assembly instructions

The mounting to the storage flange is by means of a hexagon nut and hollow disk (included). To avoid vibration failure, the finned tube heat exchanger should be supported in a suitable manner not only for transportation but also in operation.

The mounting is done in the (cold) bottom part of the tank if heat is to be added and in the (hot) upper part if heat is to be withdrawn from the tank water. The position may be horizontal or vertical. The seal is generally placed on the outside, but is also possible on the inside. When fixing the nut, it is necessary to counterhold at the fitting flats.


Quality Assurance

Responsibility begins with a high standard of quality. As the first company for semi-finished products in Europe, we have been on the path to certified quality management since 1987.
Today, we have DIN EN ISO 9001:2015 certifications for all producing plants, and our testing laboratories in Ulm and Vöhringen are additionally accredited to DIN EN ISO/IEC 17025:2018.

Pressure Equipment Directive

WRW heat exchangers correspond with the Pressure Equipment Directive 2014/68/EU. Our standard heat exchangers are leak-tested with an overpressure of 50 bar. On the refrigerant side, they are cleaned in accordance with DIN 8964, dried, filled with nitrogen and sealed with plastic caps.
