Overview

Usage

The ProMix 2KE is an electronic two-component paint proportioner. It can blend most two-component paints. It is not for use with quick-setting paints (those with a pot life of less than 5 minutes).

•Has dynamic dosing capabilities. It dispenses mate- rial A, monitors fluid flow, and dispenses material B in doses to cause the mixture to stay on ratio.

•Can proportion at ratios from 0.1:1 to 30.0:1.

•Will display the last 50 errors with date, time, and event. The optional USB upgrade kit will log 500 errors and up to 2000 jobs.

•For systems with one gun, an optional Gun Flush Box provides an automated flushing system for a manual spray gun.
