Safety heat exchangers from DELLER Safety Heat Exchangers



A safety chamber is created by using double tubes and double tube plates. This guarantees that the tube and shell media will neither mix nor become contaminated in the event of a leak. The safety chamber is empty and can be monitored by pressure or vacuum.

Alternatively, heat exchange can be optimised through the use of a neutral liquid in the safety chamber. In the event of a leak, the pressure in the safety chamber increases activating an optical or acoustic signal. The heat exchanger can be repaired or replaced; emergency shutdown is not required.
