Aalborg EH 640x360 v2

Versatile booster and auxiliary oil heater

  • Efficiently heat lubrication oil, heavy fuel oil or other viscous fluids in marine and industrial applications
  • Adapt the heater design to your application using the wide range of customization options
  • Install horizontally or vertically to fit the available space
  • Rely on constant outlet temperature with an accurate electronic thermostat, which engages or disengages heating elements as needed

The Aalborg EH is primarily used for booster or backup oil heating on marine vessels. It has a flexible shell-and-tube design and is well suited for applications where electric power is the cheapest or only available power source.
