Chromalox PFC Hot Oil Heat Transfer Systems are engineered to operate up to 600°F at atmospheric pressure (non-pressurized). They are used with Mobiltherm®, Ucon®, Caloria® and other medium temperature heat transfer fluids which do not require pressurization to operate at temperature.

PFC systems use a cold expansion tank (optional) that is open to the atmosphere. A cold expansion tank eliminates the need for nitrogen (N2) purging and reduces the tendency of the heat transfer fluid to oxidize and deteriorate.


PFC systems are ruggedly constructed and completely self contained (except for the optional external expansion tank). They are similar to the COS system except they use a high temperature centrifugal pump instead of a positive displacement pump. The centrifugal pump has a labyrinth seal ring which does not require cooling up to its maximum operating temperature of 600°F. PFC systems come complete with heaters, controls, pumps, valves, safety devices and necessary plumbing. Systems are factory tested and ready to operate.

Overtemperature Cutout protects elements and fluid from overheating

Electrical Interlock between pump motor and heating element contactors

Flexible Piping before and after pump absorbs vibration and prevents pump damage from thermal expansion
