The boiling range of the product at atmospheric pressure is above the use limit. The heat transfer medium can be used up to a maximum bulk temperature of 350degC. The film temperature should not exceed the limit of 380degC (716degF) either significantly or for a prolonged period.\u003c\/p\u003e \u003cp\u003eMARLOTHERM\u003csup\u003e\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eSH is most suitable for indirect heating of reactors, polymerisation vessels, distillation columns, heat exchangers in process plants and systems for heat recovery.\u003c\/p\u003e \u003cp\u003eMARLOTHERM\u003csup\u003e\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eSH is also suitable for use in heating and cooling systems.

Steam tracing is generally not necessary. At external temperatures below -5degC, the heat-transfer medium should be protected from excessive cooling during the shut- down phase, or the viscosity of the charge can be lowered by mixing with an appropriate amount of MARLOTHERM\u003csup\u003e\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eLH.

Nitrogen is a suitable inert gas. Inert gas blanketing is the best protection against changes caused by oxidation. Antioxidants are unstable at operating temperatures above 200degC and are ineffective even after short operating times.\u003c\/p\u003e \u003cp\u003eMARLOTHERM\u003csup\u003e\u003c\/sup\u003e\u003cspan\u003e \u003c\/span\u003eSH is thermally stable at very high operating temperatures.
