It is a well-known fact that ROWASOL liquid colors can be a clever alternative to conventional masterbatches. A more effective color yield thanks to perfect dispersion and a higher quality due to a better distribution of colorants help keep the coloring costs down in many applications. But disposing of the containers and any residual colors causes extra work and additional costs, with negative effects on the life cycle assessment. To combat this, ROWASOL is now offering its self-developed COLOR CUBE multi-use system. This is a roto-molded, sturdy container of HD-PE with a capacity of around 22 liters. It is perfectly matched to the ROWAMETRIC dosing concept, but can also be used with a variety of other pump systems. The special design allows you to stack COLOR CUBEs – enabling space-saving storage and the dispatch of up to 18 containers in a transport box with a pallet format. Just as practical: the COLOR CUBEs ‘commute’ between ROWASOL and the customer. ROWASOL fills the CUBEs and delivers them free to the customer’s door, who then uses the color and sends the CUBEs back to ROWASOL for refilling. This results in a very sustainable cycle compared to conventional disposable containers. The fact that the CUBEs do not have to be washed out also spares the environment. Due to technical reasons a small amount of color always remains in the bottom of the container and this is homogeneously mixed with the new color during refilling. Only the newly added amount is charged for and so the customer only pays for the quantity of color he actually consumes. This completely does away with any residual amounts and the trouble of disposing of the containers.

The closed system with a quick-lock coupling at the outlet and the diaphragm venting valve guarantee clean and easy work with liquid colors without any risk of contamination.

The figure shows a COLOR CUBE in conjunction with a gravimetric peristaltic pump. This combination allows a very fast change of colors because the hose and COLOR CUBE can be easily exchanged. The specially designed container carrier ensures a good emptying of the CUBE thanks to the angle of inclination.

The COLOR CUBE can be ordered in a number of standard colors on request.
