ESCRIPTION
The GasTrac Process Air Heater is a stand-alone, gas-fired
heater designed to replace the electric process air heater in an
existing dehumidifying dryer or crystalizer. The GasTrac
allows plastics processors to convert existing electric equip-
ment to a less-expensive gas source.
The GasTrac contains a metal-ceramic burner, heat exchanger,
combustion system and temperature controller to set and
maintain the temperature of the air entering a drying hopper.
The host dryer's desiccant beds dry the air. The host dryer's
process blower circulates air through the GasTrac heat
exchanger and the hopper.
The GasTrac's temperature controller, ignition system and
burner safeguards communicate with the host dryer through a
RS-485 serial interface port.
The GasTrac can be used successfully in applications that
require:
Drying of hygroscopic plastics at temperatures ranging
from 250˚ F to 350˚ F.
Hot air drying of non-hygroscopic plastics.
Process, or drying, air flow of 600 to 1800 cfm. Higher
or lower air flow ranges may be achieved, depending on
the model of the host dryer and the GasTrac selected.
Central drying, using an existing electric dryer with a
single GasTrac or multiple GasTrac units.
The GasTrac has been designed and configured at the factory
for use with natural gas only. If you want to use a different gas
fuel source, such as propane, you must contact Conair.
