How Does the Comix Bitumen Sprayer Work?
The Comix Bitumen Sprayer follows a controlled process from tank filling to application and cleaning.
Step 1 - Tank Filling
The built-in loading system fills the insulated tank from a bulk bitumen source, and the burner heats bitumen to spray temperature.
Step 2 - Pre-Spray Setup
The operator selects the required application rate and unfolds the spray bar to the needed working width.
Step 3 - Spray Operation
As the truck moves, speed detection automatically controls pump output to maintain uniform bitumen application.
Step 4 - Manual Application
The hand spray attachment is used for junctions, structures, kerb lines, and areas the main spray bar cannot reach.
Step 5 - End-of-Day Cleaning
The pressure cleaning system flushes the full bitumen circuit, leaving pump, lines, spray bar, and nozzles ready for reuse.
