Filter Refurbishment

Industrial filters are durable and can operate for not only years but decades. That said, from time to time they need some retouching to return the old equipment into its original state. We have strong experience with filter refurbishments all over the world. The work can be done either onsite or offsite – we adapt to your needs. All spare parts are of high quality, selected with attention and installed with utmost precision.

We refurbish the following filter types:

Filter presses (horizontal)
Tower presses (vertical)
Ceramic disc filters

Filter Expansion: Tower Press and Filter Press

Many plants decide for filter expansion to increase its capacity and production volume. By adding more filter plates you can improve the filter’s performance in a relatively short time.

Which filters can be expanded?

Mostly, we work on Tower Press filters and Filter Presses with an expansion option.

Adjust Auxiliaries to the Expansion

Before any filter expansion, have a closer look at the filter auxiliaries. If you are planning to increase the production volume, you should make sure that the auxiliary equipment will be able to handle the bigger volume. We do it all for you:

Make sure that the rest of the process will be able to handle the expansion
Check the sizing of the existing auxiliaries: feed pumps, air compressors, slurry tanks, conveyors …
Recommend and supply necessary equipment upgrades

When Old Meets the New

Expanding a filter is a good way to get a bigger filtration area and higher capacity. But when combining old and new equipment, compatibility is another important aspect. We have expert knowledge and make sure that all new parts are fully interchangeable with the existing ones.

Modernisation of Dewatering Equipment

Modernising existing filter units bring lots of advantages. With minimum effort, you can modernise the existing filter or other dewatering equipment and reach better efficiency, capacity, safety and more.
