Tank heater 800 WR / 400 WR

The series 800 WR heating inserts feature design characteristics which make these units unrivalled on the market. The high variability of the design allows a perfect adaption to any process conditions. There is no better solution to heat up tanks.


The series 800 WR heaters consist of a flange with bolted in heating elements. The heating elements can be exchanged with standard tools. The design of the heating elements ensure excellent thermal reaction time and control accuracy.

Heat transfer

Due to the perfect hydraulic flow around the heating elements, the medium is gently heated to the specified temperature. The surface load (W/cm²) can be precisely adapted to the medium characteristics. Recommended surface loads:

3,5 W/cm²

aggressive media (e.g. chlorinated water, bilge water,…)

6,5 W/cm²

potable water, cooling water with additives



Features & options

All heaters are equipped with built in safety temperature limiters (STB). Optional additional safety devices: flow switch, temperature limiter (self reset), PT-100 sensors and safety valves

Insertion vessel Type 400: Flanges according DIN EN 1092-1/11B1/DN15-DN250/PN16
The connection diameter can be adapted on request.
