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
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
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
