can ignite many coating materi-
als and cause a re or explo-
sion.
Parts being sprayed and operators in the spray
area must be properly grounded.
Parts being sprayed must be supported on con-
veyors or hangers that are properly grounded.
The resistance between the part and earth
ground must not exceed 1 meg ohm. (Refer to
NFPA-33.)
Operators must be grounded. Rubber soled in-
sulating shoes should not be worn. Grounding
straps on wrists or legs may be used to assure
adequate ground contact.
Operators must not be wearing or carrying any
ungrounded metal objects.

objects are within the sparking distance.
Explosion Hazard –
Incompatible Materials
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1,-Trichloro-
ethane are not chemically com-
patible with the aluminum that
might be used in many system
components. The chemical
reaction caused by these sol-
vents reacting with aluminum
can become violent and lead to
an equipment explosion.
Aluminum is widely used in other spray ap-
plication equipment - such as material pumps,
regulators, triggering valves, etc. Halogenated
hydrocarbon solvents must never be used with
aluminum equipment during spraying, ushing,
or cleaning. Read the label or data sheet for the
material you intend to spray. If in doubt as to
whether or not a coating or cleaning material is
compatible, contact your coating supplier. Any
other type of solvent may be used with aluminum
equipment.

GENERAL DESCRIPTION
In automated nishing applications, the expansion
of pressurized air causes cooling which may result
in condensation on surfaces of electrostatic ap-
plicators. The Ransburg Air Heater Assembly is
designed to reduce or eliminate condensation that
may form in or on the Ransburg TurboDisk and
RotaryAtomizers, or other pressurized applicators
under certain operating conditions.
Ambient temperature and relative humidity in most
installations is hard to maintain. The Air Heater
Assembly is designed to maintain the temperature
of your operating air supply to ensure no moisture
or condensation will occur on/in the applicator or
its feed or exhaust lines. This helps reduce high
voltage faults and rejected parts due to excess
moisture issues.
FEATURES AND
BENEFITS
• Heats up quickly and accurately - Allows
system users to ramp up production in a mini-
mum of time.
• Self contained - Small, compact cabinet fea-
tures plug'n play components making it easy
to t into existing systems or add into planned
system designs.
• Cabinet is "touch-safe" - Exterior of the
heater is cool to the touch.
• Precision control - Provides users with ac-
curate temperature feedback via audible and
visual displays and alarms.
• Heats drive-air to optimum temperature
INTRODUCTION
- Heats as required to keep rotator housing
warm enough to prevent condensation by
maintaining exhaust temperatures above the
dew point.
• The actual heater process setting depends on
applicator uid ow rate, booth conditions, air
ow, inlet and ambient air temperatures. The
heater should be set as low as possible, sufcient
to maintain the applicator surface temperatures
above the dewpoint of the booth environment.

LOCATION
INSTALLATION
Install the air heater near the applicator, but in an
area outside of the hazardous location. The unit
should be located so that it is not exposed to water,
paints or solvents, and high temperatures. (The
ambient temperature should not exceed 120°F.)
INPUT POWER
Input supply voltage connection should be made
from a fused disconnect. Route the input power
wires through the side of the cabinet. Generally,
conduit should be used for the input power. (Always
comply with national and local electrical codes.)
PNEUMATIC
CONNECTIONS
Use appropriate size piping to connect the air
heater to a ltered inlet source. The air heater
compressed air input is at the bottom of the unit
and is identied as "IN". Connect the heated air
output located at the top of the unit identied as
"hot outlet pipe" to the coating applicator(s) using
1/2-inch OD, nylon 11/12-inch tubing, with proper
pressure rating.
Asecondary sensing air supply must be connected
to the pressure switch [8] through 1/4-inch OD
tube tting [29].
If the unit is being wired directly to the PLC elec-
trical connections, the pressure switch must be
by-passed. (Refer to "Figure 1: Installation Op-
tions" for assistance.)

OPERATION
PRINCIPLES OF
OPERATION
The Air Heater system is shipped as 230V/
1 phase 50/60 Hz operation but can be converted
with simple jumper changes to 115 volt operation.
Heater and controls are contained in a single,
steel Type 12 enclosure vented to the atmosphere
through access ports for compressed air delivery.
Three LED indicator lights indicate the status of the
system. Green indicates a "power on" condition.
Red indicates an "alarm condition" resulting in
shutdown of power to the heater. Amber indicates
"insufcient air ow" for safe operation. The red
or amber light remains steady when ON or can be
jumper selected to ash when ON. In addition, an
audible warning option is also jumper selectable
to sound in intermittent warning when either the
red or the amber light is lit.
If an alarm condition occurs such as high tempera-
ture or insufcient air ow, the power to the heater
is interrupted by the safety contactor. When the
alarm condition is removed by the heater cooling
off or the airow increasing, the heater will be
energized and operate until the system is turned
off or the next alarm condition occurs.
The heart of the control process is the temperature
controller. Upon startup, or immediately follow-
ing the acknowledgement of any alarm condi-
tion, the controller's PID programming provides
a fast, smooth approach to the nal temperature
set- point. The PID parameter is set per "Auto-
Tuning Procedure" (see "Controller" manual for
"Auto-Tuning Procedure and all detailed controller
functions").
No cooling is required for the system. Air ow of
at least one (1) SCFM (28.3 SLPM) will satisfy
heater needs.

> Heating the drive-air to between
120°F and 140°F will usually keep the
rotator housing warm enough to prevent
condensation. Use ONLY enough heat to
prevent moisture buildup!
NOTE
> When turning the air heater off, rst
remove power and allow the unit to cool
prior to turning off air ow. Failure to do
so may create excessive heat in the heat-
ing element and may cause permanent
damage or reduced service life of heating
element.
