Immersion Heaters - Hazardous Area Zone 1 Zone 2 - Glycol Boilers KO Dums Tank Heating

  • Tank Heating – core and cartridge element immersion heaters provide hazardous area tank heating with exact control of liquid temperature, virtually 100% energy efficiency and ensuring a reliable and fast heat up time for water, solvents, molasses, syrups and petroleum products.
  • Glycol Reboilers – hazardous area heaters are installed within the reboiler to thermally regenerate glycol – providing a clean, efficient controllable heat source with controlled sheath temperatures so as not to burn the glycol.
  • KO Drums – electric heaters increase temperatures of separated liquids – a vapour-liquid separator may also be referred to as a flare KO drum, flash drum, knock-out drum, knock-out pot, compressor suction drum or compressor inlet drum.

This photograph highlights the challenges of servicing the worldwide oil and gas industry –  barge delivery of a knock-out drum fighting through a waterway frozen by the polar vortex. From Saharan deserts to Arctic tundra the combined challenges of temperature extremes, potentially explosive atmospheres and harshest operating environments place significant importance upon the specification of equipment in accordance with international classifications.
