Chromalox CLS Hot Oil Heat Transfer Systems
are engineered to operate up to 750°F at a
pressure of 200 psig. They are used with
Syltherm® 800 and other high temperature
heat transfer fluids which require heated lines
to prevent crystallization of the media and
pressurization to operate at temperature.
CLS systems use a pressurized hot expansion
tank (optional) that is heated by hot heat
transfer fluid flowing through it. The expansion
tank is ASME coded for 650°F @ 200 psig
with an ASME safety relief valve. Nitrogen (N2)
purging is required.
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
Inline 0.030 Mesh Strainer protects pump
Full Port Manual Gate Valves on all primary hydraulic piping minimize pressure drop
2 Inch Thermal Insulation around heating chambers minimizes heat loss
16 Gauge Painted Steel Panels on all exposed sides — powder coat heat resistant paint
Chromalox CLS Hot Oil Heat Transfer Systems
are ruggedly constructed and completely self
contained (except for the optional external
expansion tank). All CLS systems come
complete with heaters, controls, pump valves,
safety devices and necessary plumbing. The
high temperature cast steel centrifugal pump
is provided with a water cooled mechanical
seal designed for continuous operation at a
maximum temperature of 750°F. CLS systems
are factory tested and ready to operate.
WARNING — In hazardous areas, pipe surfaces
could achieve temperatures high enough
to cause auto-ignition of the hazardous
materials present. Consult Article 500 of the
National Electrical Code for further information
on the maximum allowable temperatures for a
specific application.
