3.1 PRODUCT FEATURES
The AccuCoat
®
HD15 In
-
Line Heater is an add
-
on unit that can be paired with many of the Precision Spray Controllers
offered by Spraying Systems Co.
®
such as AutoJet Technologies 1750+ and 2150+ spray control panels to provide heat
to your spray application. The HD15 comes available in a threaded version with push
-
tube fittings or a sanitary version
with clamp
-
style connections. All wetted parts are constructed of 316 stainless steel and VITON
®
seals.
The in
-
line construction allow heating to be achieved only on
-
demand for optimal response and energy efficiency. The
heater is made with food contact materials to ensure food safety. It can be used with light oils, sugars, syrups or re-
lease agents to help achieve consistent, uniform coverage, minimize clogging problems, and ensure the proper volume
of coating to the target. The system should not be used with fluids that solidify at room temperature.
WARNING: Do not enable heating without fluid in the system.
SYSTEM USAGE
The HD15 heater can be used to feed the nozzle directly or use a liquid recirculating system through nozzle or outlet
bypass. The system is designed for optimum performance using the recirculation feature of the AutoJet SCS Series
Pump System or Coating Supply Unit. This will ensure consistent temperatures and uniform spray.
Heating capabilities are a factor of the heater, flow rate, and the properties of the fluid (specific heat
C
p
, density, inlet
temperature, etc.).
RESPONSE LIGHT
Light is illuminated when power is being provided to the heater. The temperature controller utilizes a PID control loop
to control the heater. This means that during the course of operation the light (indicating power to the heater) will
vary from fully on, blinking quickly, intermittent pulses, or off for a duration of time even when the system is heating.
