Safety heat exchangers

When safety is your number one priority

The range of safety shell-and-tube heat exchangers is based on the “three chamber devices” principle, which was developed
and patented by the company’s founder Karl-Heinz Funke.

Operating principle of a safety heat exchanger with double tubes, double sheets and leak sealing liquid

V = volume expansion tank, P = pressure control device, yellow area = safety space

Design Features

Media separated by double tube bundles, media cannot mix
Special sealing liquid for immediate leak indication
Leakage system works independently of the installation position
Leakage detection is possible through process control
Suitable for a wide range of liquid media

Application

Safety heat exchangers are used wherever the highest requirements for product purity in process engineering (e.g., food/pharmaceutical industry) are required, where there is an environmental risk of contaminating cooling or process water, or because mixing of the media can damage the machine or system.
