Elwa 4624RF Flowheater

The series 4600 heaters 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. Thousands of these heaters are in service on ships, in power stations or industrial applications all over the world.

Design

The series 4600 heaters consist of a welded pressure vessel with an electric heating insert. The heating elements are positioned in protection tubes and are not in direct contact with the medium. They can be exchanged without draining and opening the pressure vessel. 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:

0,8 W/cm²

lube oil/low flow rate of medium

1,1 W/cm²

high viscosity heavy fuel oils and average flow rate of medium

1,4 W/cm²

marine diesel fuels, light diesel fuels and high flow rate of medium
