Aluminium Bending Process – Croffle Cover Balls saving cash for factory

Cover Balls saving some serious £’s

Back in 2011 Euro-Matic supplied cover balls, also known as Croffles to our friends at ABS, an aluminium bending factory plant which makes window frames and other supports for the building trade. With a large deep tank needed to bend the aluminium heated to 98 degrees, it is a costly job keeping such a large tank at the correct temperature.

Euro-Matic croffle cover balls have been saving money by preventing up to 90% of the water loss as they have happily given a protective layer on top of the water, but enabled the water level movement as they required.

How long do they last?

ABS, needed to do some serious repairs to their tank, and decided to give it a good clean out, as you can see from the photo, the old balls are still functioning, despite having a layer of degreaser on them which is causing a few of them to sink. So after at least 6 years, we supplied them with a lovely set of new 50 mm PP clear cover balls on a next day delivery, just in time for their tank to be refilled and functioning again.

What are the other uses?

So for ABS, the primary reason for using the balls is to prevent heat loss and save on heating bills, but the other benefit is the reduction of escaped steam into the factory, which can cause corrosion to the roof and surrounding areas.

Where chemicals are used, toxic gases can also be prevented with the application of balls onto any water tank or liquid tank and a generally nicer working environment in factory processing plants can be created.
