OMEGALUX® CS Series cartridge
heaters provide high wattage
in limited spaces. They are
manufactured with 300 Series
stainless steel sheaths to precise
dimensions and tolerances to
ensure maximum heat transfer
for minimum core temperature
and faster heating. The CSS
Series cartridge heaters feature
an economical design of coiled
resistance elements and ceramic
cores and can be used whenever
a high watt density is not required.
The CSH Series consists of high
watt density cartridge heaters that
feature a swaged construction,
which allows for longer life at higher
temperatures. See next page for
the maximum recommended
watt density when selecting the
high watt density CSH Series
cartridge heaters.
CSS and CSH Series cartridge
heaters are designed to fit holes

lower the maximum allowable watts per square inch.

Standard Construction CSS Series
All cartridge heaters are rated by wattage and watt
density (watts per square inch) for either 120 or 240
volt operation. In some applications it may be useful to
derate the wattage by operating the cartridge heater at
a lower voltage. When operating at lower voltages, the
wattage is derated using the following formula:
(Operating Voltage/Rated Voltage)2
x Wattage at Rated Voltage = Derated Wattage
Example: The CSH-5102000/240 cartridge heater
is rated at 2000 watts and 90 watts per square inch
at 240 volts. To determine the derated wattage when
operating on 120 volts:
(120 Volts/240 Volts)2 x 2000 Watts = 500 Watts
When operating on 120 volts, the watt density of this
heater would also be reduced by a factor of 4 from
90 watts per square inch to approximately 22 watts
per square inch.
