Keg external washer


Co.Mac range of external washers includes machines consisting of a various number of sections, depending on both line speed and type of cleaning to be performed.

Our smallest machine has a useful length of 2 meters, one section and one lane, and performs a simple washing with water (hot or recovered). The next model, which can be 3 or 4 meters long, is designed to perform a first pre-washing with recovered water, a washing with caustic solution to remove the ink-jet code, and a final rinse with clean water.

These basic configurations can be increased with further sections, to extend the pre-washing. drain the water sprayed by the first showers and recover the next, extend the caustic washing, add a high pressure cleaning section if labels must be removed from kegs, etc.

In case of high capacity keg lines, the external washer can even be designed with two lanes.
