    Customer Requirement:

    The customer faced a challenge of increasing rejections in the Paint shop due to faulty color selection by operator. Also manual color change was time consuming, affecting the paint shop efficiency. They were looking for a system that could automate the color change action avoiding operator dependency, thus reducing rejections and making the
    process quick and efficient.

    System Specifications:

    We delivered a systems that allows automatic recovery of the non-applied paint & cleaning of the system – Patvin’s RECOCLEAN system, a pig-less paint-push-back-system between Color Change Units and Atomizer.

    RECOCLEAN uses dry air to push back paint from the Atomizer to the Color Changer and clean the fluid line including built-in components.

    A unique feature of the system resides in the ability of the discharge system to automatically separate and isolate the original paint from the new color paint, so that the purged paint may be collected in a segregated container and re-used, enabling significant cost savings.

    System Key Components:

    • PLC control panel (Qty- 1no) – Receives color input from Automation control and Initiates color change
    • Color change Valves (Qty- 1 set /stn.)
    • Solenoid valve Bank (Qty – 1 no/stn.) – Receives command from PLC and triggers CCV
    • Gun Flush Box (Qty-2 nos /stn.) – Triggers spray gun during color change operation
    • Color sensor (Qty- 2 nos./stn.) – Ensures push of paint during color change
