✴ Maximum operating temperature
of 425°F (218°C).
✴ Power cord is 6-foot long, SJO Type 16/3
complete with three-prong plug for 120 VAC
models. Plugs are not included on 240 VAC
models but are available (see page 15-15).
✴ Surface grounded electrically with internal
ground screen.
✴ 1250 volts dielectric tested.
✴ Vulcanized silicone rubber construction
resistant to moisture, ozone, fungus, and
radiation.
✴ Adjustable thermostat, see page 9-16 for
specifications.
Tempco flexible drum heaters can save time by heating stored viscous
fluid to a pourable temperature.
The heater is built to be tough, long lasting, and resistant to chemicals.
Because few materials stick to its silicone rubber with fiberglass reinforced
construction, it is easy to clean. The heater comes with a 6-foot cord and
plug (120V only). When not in use, it rolls for convenient storage.
The total wattage (number of heaters) and the material being heated inside
of the drum must be considered when determining the actual temperature to
which that specific material can be heated.

Thermostat Control models sense temperature in
an area remote from the heating element and will automatically cycle heater to maintain set temperature.
Three-heat switch allows three wattage ratings per
thermostat setting and voltage rating.
Infinite/Variable Control models cycle the current
ON and OFF. The ratio of ON time will increase as the
control is advanced. Three-heat switch allows the operator to control the heater output within a given 3 settings of high, medium, or low.
Standard lead time is Stock to 2 weeks.
