Thermal cleaning of candle filters and filter disks

The gentle and repeatable cleaning of candle filters (filter candles) and filter disks (disc filter) as well as complete filter bundles is an important quality factor, among others, in fiber and film production. Polymers are removed in a single step – including possibly existing tacky particles – using vacuum pyrolysis (VACUCLEAN) or hydrolysis.

 

Inorganic remnants are removed using a select after-treatment method (high water pressure, ultrasound). The HYDROLCLEAN cleaning system facilitates the gentle and effective cleaning of all metallic filter media. The HYDROLCLEAN system requires between six and 12 hours for the complete cleaning process. Any risk of thermal or mechanical damage to individual filter layers is eliminated.

The gentle and repeatable cleaning of filters from screen changers is an important cost and quality factor in extrusion. Multiple cleaning is possible, depending on the type of polymer and the design of the filter screen. Polymers are removed in a single step. Inorganic remnants are removed using a select after-treatment method (high water pressure, ultrasound).

 

The INNOVACLEAN cleaning system, for example, takes only two to four hours to clean die plates. The cleaning system eliminates any risk of thermal or mechanical damage to the parts.
