ERH 4600 WR (water/emulsion)

The series 4600 WR heaters offer highly effective heating power for processes with water or similar media. The heating elements can be perfectly adapted to the customers application.


The series 4600 WR heaters consist of a welded pressure vessel with an electric heating insert. 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.

The heaters come with an efficient thermal insulation made of rockwool and galvanised steel sheet cover. The cover is also available made of stainless steel (polished upon request).

Standard: Flanges according to DIN EN 1092-1/11B1/DN15-DN250/PN16
Optional: Triclamp or threaded connections
The position of the connections can be adapted on request.
