heaters

component

Component heaters may be used by
themselves to solve many heating prob­lems. They may also be incorporated into
more complex heating systems, providing a
complete thermal solution for your heating
requirements.

Chromalox carries the widest selection of
standard component heaters in many shapes,
sizes and wattages. Chromalox is the “First
Choice for Thermal Solutions”.

Applications

With component heaters, most often the shape
and size will be the determining factor in most
heater applications. Brief descriptions of each
heater type follow, with selection guidelines
that lead to a detailed description on individual
product pages.

Tubular heating elements perform excep­tional heat transfer by conduction, convection
or radiation to heat liquids, air, gases and
surfaces. In most heater assemblies, tubular
element design configurations vary — round,
triangular, flat press and formed. Bends are
made to customer requirements Custom built
from 0.200" to 0.475" diameters, a multitude
of sheath materials with sheath temperature
capabilities up to 1600°F, watt densities to fit
many applications and up to 600 volts. Avail­able with over 20 optional terminations and
many stocked accessories.

Thin blade heater elements provide more
surface area than standard tubular elements to
offer greater wattage or lower watt densities.
Select from many sheath materials with watt
densities to 75 W/in
as high as 1200°F. Heating elements can be as
long as 120" and are capable of being formed
into many configurations for heating via im­mersion, direct surface contact or convection.
Three wire construction within the element
provides uniform heating. Available in single
or 3-phase current terminations with a 120 to
240 volt range.

Application Guidelines

Applications (cont’d.)

Strip/Ring/Disc heating elements are rug­ged and easy to install for heat transfer by
conduction or convection to heat liquids, air,
gases and surfaces with sheath temperatures
up to 1600°F and watt densities to 35 W/in
Common applications include drying, melting,
baking and curing. Strip heater sizes range
from 0.5" wide to 2.5" and lengths to 72"
long. Heaters bolt or clamp to many surfaces.
Nested ring heaters can provide concentrated
heat in small areas. Select from many sheath
materials, termination styles, operating tem­peratures, sizes, voltages, wattage ratings and
mounting devices.

Band heaters grip tightly to cylindrical sur­faces to supply uniform heat transfer, critical
to the heater life. Chromalox band heaters
are flexible and come in one or two-piece
construction for easy installation and removal.
They accommodate diameters as small as
15/16" and as large as 20" and are capable of
reaching sheath temperatures up to 1600°F.
Stainless steel braids and conduit protect
terminations and resist contamination. Com­pletely customize your heater by specifying
exact physical dimensions, material, electric
ratings and terminations.

Cartridge heaters are high efficiency heating
elements. Diameters of cartridge heaters range
from 0.25" to 1.25". Watt densities from 25

to 200 W/in2 and sheath temperatures to
1600°F. Optional end seals resist contaminants
and moisture from entering inside the heater.
Chromalox provides a variety of sizes, wattage
ratings, voltages and protective features to
meet many challenging applications.

Flexible heaters are very versatile and provide
solutions to a vast number of low-to-medium
temperature applications. Heaters are manu­factured with rugged light-weight materials
providing chemical and moisture resistance
with operating temperatures to 390°F. Wire
elements are durable and wound precisely
within the structure for optimal performance.
A variety of electrical, shape and contour fit­tings to meet many specifications.
