Watlow CAST-X 500 User manual

Safe Circulation
Heater Ideal for
Contamination-Free
Gas and Liquid
Heating
The new CAST-X 500 from Watlow®is a small, lightweight
circulation heater ideal for heating gas or liquids in
demanding applications. Even in its compact size, the
CAST-X 500 is extremely powerful with operating
temperatures up to 350°F (177°C) and working fluid
pressure up to 3000psi. The CAST-X 500 heater is
available in a variety of wattages and can be shipped in
just a few days.
The CAST-X 500 heater is constructed of a helical coiled
tube cast into an aluminum body with a replaceable cartridge
heater installed in the center. The cartridge heater can be
replaced with various wattages to suit your equipment’s
changing requirements.
The aluminum body serves as the heat transfer media
between the cartridge heater and the coiled tube where
the fluid is being heated. The aluminum mass acts as a
“thermal flywheel” and ensures accurate temperature control
of the fluid to prevent degradation.
The unique, non-weld construction of the CAST-X 500 allows
it to be used where thermally sensitive materials are being
heated such as paints, resins and flammable materials.
The heater is suited for applications where fluid cleanliness
is critical, because the material being heated never comes in
contact with the heater. This is a performance requirement in
foodservice, semiconductor and analytical industries.

•Assures an intrinsically safe thermal solution
•Prevents fluid contamination upon heater failure
•Heats sensitive materials safely because the material
heated does not come in contact with heating elements
Robust cast-in aluminum construction
•Assures longer heater life
•Offers accurate temperature control
Non-welded construction
•Minimizes potential leakage
•Offers an economical priced package
•Provides high pressure operation to 3000 psi
•Self draining when mounted vertically
Standard stainless steel fluid path
•
Assures material compatibility with many different materials
Replaceable cartridge heater
•Offers low cost of ownership due to ability to replace
heater in field
•Assures faster delivery and customization from factory
Compact size
•Assures quick response due to low mass (2.375 lbs)
•Saves real estate in equipment because of small footprint
