5. OPERATING PRINCIPLES
The compressed cold air of the general air line is
connected to the input where the flow meter (No.5)
monitors the air flow (intake) required for the
operation of the resistance and based on it’s
value, it will turn the heater on, or keep it off.
The cold air enters the pressurised chamber
cooling the shell of the equipment, containing
keeping it isolated from the hot chamber (No.7)
that contains the resistance used for heating the
air.
The air rises up through the central part of the hot
air chamber (No.7), going through the resistance
and is then heated to the programmed temperatu-
re and is piped out where the temperature sensor
is located (No.4) to its point of consumption (spray
gun or application tool).
The cold air chamber (without pressure) (No.6) is
the container for the PID temperature controller
and the other electrical components, including the
Main switch (No.2) and the “Ready” pilot light
(No.3).
To connect the equipment main switch (No.2) is
used.
The desired temperature of hot air at the outlet of
the equipment is determined using the controls
(No.1) of the temperature controller, which can be
accessed by removing the protective cover.
Once the adjustment has been made, refit the
protective cover. The temperature controller
(Proportional Integral Derivative) ensures that the
output hot air temperature is maintained constant.
The heated hose prevents heat loss of the air.
