Preheater KVES

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


The KVES series is based on our approved 4600 WR series flow heater. With the mounted control cabinet and the integrated pumps we offer configurable units which can be used for many applications. We use high-quality centrifugal pumps. The heating elements can be exchanged with standard tools.

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 units 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
