The Dual-Mix System

The Dual-Mix System monitors the flow of 2K coatings to prevent off ratio conditions which result in wasted materials and poor quality finishes.

By using flowmeters, Dual-Mix continuously monitors the flow rates and volumes in each stream to maintain the correct ratio of resin to catalyst. Should the ratio vary by a preset amount, a visual/audible alarm is activated and a solenoid valve shuts down the delivery system. The flowmeters are unaffected by pressure fluctuations unlike pressure monitoring systems which can lead to false alarms. Similarly, the flowmeters act as a "fail-safe" device to provide complete assurance of continuous on-ratio mix and fluid delivery. The Dual-Mix not only provides an accurate ratio 2K coating delivery (better than 0.5%) but is also able to provide displays, alarms and print-out a variety of parameters, inculding flow rates, volumes, temperatures, levels, pot life, shift and operator identity, plus alarm reporting with date and time.
