Also available in the “SWT 100 Titanium” variant

SWT 100

The SWT 100 is perfect for solar systems, heat pumps and low-temperature heating systems due to its large transfer area. It can also offer clever details: for example, the SWT 100 has combined sleeves for variable connection options and easy installation. In addition, rubber tube clamps reduce vibrations and the noise level to a minimum.
