About Marlotherm® SH

Marlotherm® SH is recommended for use in the temperature range from 250°C (482°F) to 350°C (662°F), but can be used intermittently at film temperatures as high as 380°C (716°F).

  • Marlotherm® SH heat transfer fluid is non-corrosive
  • Marlotherm®  SH HTF can be used without being pressurised
  • This dibenzyltoluene heat transfer fluid can be used in systems requiring start-up temperatures as low as -5°C (23°F) without the need for heat tracing
  • Marlotherm® SH thermal fluid is thermally stable up to 300°C (572°F) and can be used for several years below this temperature without reducing performance
  • Low viscosity 17 cSt @ 40°C (104°F) with a pumping limit at -5°C (23°F) – making it the lowest in its fluid class
  • This thermal fluid has a high flash point 200°C – one of the highest in its fluid class
  • Marlotherm®  SH HTF has superior thermal stress resistance in the bulk outlet temperature range  from 60°C-350°C (140°F – 662°F)
