IQ SYSTEM
The IQ System is a complete, self-contained system which provides
cooler, cleaner air than from a standard portable compressor. The
system utilises an integral aftercooler, high-efficiency filtration, and a
patented condensate disposal system to provide the cool, clean air.
The condensate disposal system injects all liquid condensed from the
moisture separator and filters into the engine exhaust system where it
is vaporised by heat. This eliminates the need for collecting the
condensate, and the added cost of disposing of the condensate, which
is often regulated by local regulations.
Ensure that the compressed air temperature always remains above
freezing temperatures (typically 7°C (45°F)) at any ambient
temperature down to -23°C (-20°F). This prevents the need for heat
tracing systems, or any manual adjustment to prevent freezing of the
compressed air system. All drain points for the condensate handling
system are heated with 24VDC heaters, which are integral to the
compressor heater system.
Standard Non-Louvred configuration not to be operated below
freezing.
