RW tube bundle heat exchanger
RW tube bundle heat exchangers consist of a bundle of high-performance corrugated tubes made of copper or copper-nickel, which is brazed into a copper or copper-nickel housing. The special corrugated tubes manufactured by Schmöle have a large number of troughs or corrugations which are stamped into the tube wall from the outside. The resulting structures on the outer and inner surfaces ensure significantly improved heat transfer compared to plain tubes. Deflector plates are used to generate an outer flow around the tubes in the shell space.
RW tube bundle heat exchangers are manufactured in six different capacity sizes, with the outer diameter of the shell tubes and the overall height being the same for all capacity sizes. The construction length, which varies according to the capacity, can be seen in Figs. 1 and 2.
Benefits of RW tube bundle heat exchanger
- High heat output
because of powerful special corrugated tubes - Compact design
small need for space, ideal for retrofitting - Low pressure dropp
low energy consumption of the pump - Delivery with styrofoam shell
for heat insulation and transport security
Fields of applications
Heating domestic water
- With the shell and tube heat exchangers of the RW-B design, the heating water is routed on the tube side, heating the domestic water flowing in countercurrent on the shell side.
Floor Heating
- With the shell and tube heat exchangers of the RW-F design, the heating water is outside the tubes on the shell side, heating the floor water in countercurrent inside the corrugated tubes.
Heating pool water
- With the shell and tube heat exchangers of the RW-S design, the heating water is also outside the tubes on the shell side, heating the swimming pool water in countercurrent inside the corrugated tubes. A higher volume flow is possible through the use of copper-nickel corrugated tubes.
