DESCRIPTION
The Thermo-Aire Heater is used in situations where
oils of heavier viscosity ranges are required or where
an increase of the lubricant output capacity of lower
viscosity oils is needed. When the Thermo-Aire
Heater is incorporated in the Oil Mist Unit, oils in the
viscosity range of 1,000 to 3,500 SSU at 100° F. can
be used. The Air Heater is enclosed in a pipe and
heats the air which passes over it.
COMPONENTS
The Thermo-Aire Heater Kit is equipped with a
Cartridge Thermostat 383884 and is rated 10 Amps
at 120 VAC or 5 Amps at 240 VAC. It is installed in
the path of the heated air and automatically controls
air temperature at the factory-set temperature of
150°F. Model 383808-A4 is rated at 120 VAC, Model
383808-B4 is rated at 240 VAC.
A warning Thermostat 383842-1 is mounted on the
surface of the pipe and energizes a warning device
(visual or audible) when the heating element is not
operating properly. It is rated 10 Amps at 120 VAC
or 5 Amps at 240 VAC and has a range of 50 to
300° F. It is factory set at 125° F.
ASSEMBLY
The Thermo-Aire Heater Kit is completely assembled
at the factory except for electrical wiring and air tube
assembly.
