STARFLOW
Circulation Heater

Throughout many steps in the
semiconductor manufacturing
process, Watlow cable circulation
heaters help to improve process time
and operating efficiency. Using
clean, hot gases reduces wafer
drying time. Flameless dry heat
efficiently solders and desolders
electronic circuits and boards.
Heated gas streams quickly dry and
cure circuit boards without using a
large baking oven, saving precious
floor space. Watlow’s STARFLOW
circulation heater is specifically
designed to meet the requirements of
these applications.

The STARFLOW circulation heater is
engineered to heat a flowing gas
stream up to temperatures of 1400°F
(760°C). The 316L stainless steel
chamber houses a small diameter
sheathed element, which allows for
quick response to both heat up and
cool down cycles. Watlow’s
starwound coiled cable heater
provides extremely efficient and
reliable heating by maximizing the
contact area of the gas or fluid with
the element.

Because the element is sheathed, the
unit can operate in gas streams that
require a clean environment as well
as atmospheres that contain contami­nants and moisture. This provides
superior performance compared to
units with internally exposed or open
element wires.

Features and Benefits

• Small diameter heater allows for
quick response times.

• Internal star wound heater
element provides fast, efficient
heating.

• Sheathed element can run in
clean or impure streams.

• Flexibility in configurations allows
for adaptablity to any process.

• 316L stainless steel construction
is rugged and corrosion resistant.
