Specific surface load describes the heat transmission to the medium to be heated. The selection depends on the medium, the flow, pressure and installation conditions, as well as the medium temperature and the permissible surface temperature. High thermal efficiency is achieved through adapted specific surface load.

Guideline values:

Heavy fuel oil, gear oil, bitumen 0,8 ... 1,0 W/cm²
Hydraulic oil, lubricating oil. heat transfer oil 1,5 ... 2,3 W/cm²
Water/glycol 2... 4 W/cm²
Water 4 ... 8 W/cm²
Flowing gases 0,5 ... 3 W/cm²
Motor anticondensation heater, Room heater 0,25... 0,4 W/cm²

The materials are selected based on the customers’ requirements, the media to be heated, the temperatures and the ambient conditions.

  • Heating bundle: Stainless steel 321, 316, Incolloy or according to the customer’s specifications.
  • Flange or screw-in thread: Carbon steel, stainless steel 321 or 316, other materials according to the customer’s specifications.
  • Connection housing made of cast iron or steel with paintwork for the highest industrial requirements or made of stainless steel 316

Immersion heaters that are part of pressure equipment are calculated, produced and accepted in accordance with the specifications of the Pressure Equipment Directive, ASME VIII or other regulations.

The grouping according to the PED in accordance with the conformity evaluation for the vessel must be specified by the customer.
