Heaters with integrated Anti-Burn-System minimize the possibility of thermal damages to plants and tanks in the event of partial or complete loss of the liquid being heated.

The integrated Anti-Burn-System reacts in case of dangerous situations and switches off the heater when using one- or two-phase connection.

In case of a three-phase connection, the integrated Anti-Burn-System switches off the heater with aid of our differential current monitor DSW3/2 and a power relay. The heater remains switched off until the safety circuits in the immersion heater and on the differential current monitor are reset manually.

For technical specifications of the DSW3 / 2, see “sensors and electronics”
