Application Duratherm: XLT-2 is a liquid phase, low temperature heat transfer fluid with outstanding heating and cooling capabilities throughout a wide temperature range. This fluid is ideal for heating and cooling applications with working range as low as -84C with most efficient heat transfer between -60C and 177C. It can also be used as a secondary coolant in refrigeration loops where a wide ranging fluid is required.

Trouble Free Operation: Duratherm XLT-2 heat transfer fluid does not require monitoring of concentration or additive levels.

Enviromental: Duratherm XLT-2 is plant and user friendly. Low odors, high flash point and no SARA reportable substances makes Duratherm XLT-2 the wise choice for worker health and safety.

Disposal: After its extensive service life, Duratherm XLT-2 can typically be disposed of through local waste oil recycling programs. Check your local regulations.
