Petro-Therm™ is a heat transfer oil developed for use in non-pressurized, liquid phase heat transfer systems operating at bulk fluid temperatures up to 315°C (599°F). It is specifically formulated to provide long service life and excellent thermal efficiency in a variety of industrial applications while resisting oxidative and thermal degradation.



Petro-Therm will give long, economical service in various industrial process applications such as asphalt plants, marine, wood processing, dry kilns and institutional laundry and heating. To inquire on a specific application or for technical service advice, contact Matt Koziol below.

Service Life

PetroTherm has been designed to provide long service life under normal operating conditions up to the fluid’s maximum recommended temperature. However, actual fluid life is dependent upon system design and maintenance practices. It is recommended that the oil’s condition be monitored on a regular basis as the rate of change of physical characteristics is more significant than the actual values.
