ProMix PD: a closer look at colour changing

Many factory paint mix rooms and spray booth environments require operators or machines to spray several different colours over the course of the day, a cumbersome process that wastes significant amounts of time and material. The ProMix PD can be equipped with a colour change module to solve this problem once and for all.

How does it work?

Colour changes traditionally require operators to flush all of the equipment and the hoses with solvent to ensure that absolutely no contaminants or differently coloured leftover paint remains in the system. This is a time-consuming and costly step that wastes a lot of time and material.

Why is the ProMix PD’s colour changing process unique?

In combination with a ProMix PD multiple-pump setup, the optional colour change module can send up to 30 colours through different hose bundles using a set of valve stacks. This way, colours are completely isolated from each other and the ProMix PD can instantly switch from one colour to another. Custom valve mapping allows you to configure your hardware and control the inlet, outlet and remote valves from one single module, so you can optimise your solenoid and valve usage.

What are the main benefits of the ProMix PD’s colour changing process?

Save time and reduce material waste with these colour changing benefits:

• Faster colour changes
  One of the ProMix PD’s main characteristics is the fact that the mixing point is moved as close to the gun as possible, which leads to a minimal flush zone and ultimately to faster colour changes. Colour change times are further reduced by the use of air/solvent chop and preset flushing routines, which make the whole process more efficient. 

• A flexible environment
  The ProMix PD can manage up to four pumps and 30 colours simultaneously. When each pump is connected to separate valves with dedicated hose bundles per colour, instant colour changes are possible. In manual setups, colour changes can be controlled by the operator from the booth, using the ProMix PD’s convenient booth control. 

• Efficient use of time and materials
  Not only can optimised colour changes save you a lot of time, moving the mixing point closer to the applicators also means a drastic reduction of material waste. This change can reduce your daily paint usage by up to 70% compared to competitors’ setups. This also gives you the extra benefit of a reduced disposal cost for hazardous material.

• Increased productivity
  The ProMix PD’s unique colour changing process will boost your productivity. Thanks to its multiple-pump setup and smart valve stacks, you can enjoy instant colour changes, as you can flush one colour while another is being sprayed.

Colour changes have never been this smooth and effortless. Customise your ProMix PD setup and get ready to spray up to 30 colours with instant colour changes. Your productivity will go through the roof, while you save time and money.
