Flanged Heaters (FH)

For heating oil, water, drinking water, air, CO2 and other gases


We manufacture and supply flanged heaters in all international standard flange sizes (ANSI, DIN, metric, JIS, BS) and customer-specific designs. The flange heaters can be installed horizontally or vertically. Through the use of support tubes, the heaters are extremely stable, thus resulting in a long service life and reliability in operation.

Our flanged heaters are also distinguished by these properties:

  • Pressure testing up to 40 bar is possible at our plant
  • Connection housings are available, up to Protection Class IP67
  • Unit testing according to DIN EN 60335 (VDE 0700)

For high or low temperature applications, the heaters can be supplied with a cooling section KS. Additionally, the heaters can be equipped with temperature
thermocouples, switches and safety elements. Different sheath materials are available to ensure optimal heating for specific applications.

Important Instructions for Flanged Heaters

Please consider the applicable surface loads for the heating of various media. When used in liquid, the tubular heater must be completely immersed. The fluid circulation must not be hindered by the heater. Seals are included. The heater must be kept free from deposits and contamination. Hard water causes scale deposits on the heating elements and can lead to overheating. Reducing the surface load can reduce the calcification. Water containing free chloride ions can also shorten the life of the heating elements by, among others, pitting.

When placing an order, the following parameters must be specified:

  • Voltage, power, connection
  • Maximum immersion depth and unheated length
  • Flange size
  • Protection class and execution

Information on the type of application (temperatures, medium to be heated) simplifies the choice of matching sheath materials and surface loads.
