Herding BETA – The Sinter-Plate Filter for higher Temperatures

The newly developed Herding® BETA filter element has the unique and proven properties of the Sinter-Plate Filter and is specially designed for use at higher operating temperatures.

Well-proven properties now also up to 160 °C

The classic Herding® Sinter-Plate Filters with PE-based matrix base materials can by definition be used at operating temperatures of up to 70 °C and, as a thermostabilized variant, up to 100 °C.

The new developed and patented Herding BETA, based on a sintered matrix made of PPS, now allows the use of all known features of the classic sinter-plate filter up to a continuous operating temperature of 160 °C.

The new filter medium represents a very versatile filtration technology, which is extremely resistant to chemical attack and also hydrolysis, as well as having a range of 1 - 10 with regard to pH resistance. Absolutely constant operating conditions due to the above-described pure surface filtration are also possible with the Herding BETA for operating temperatures up to 160 °C. In addition, the new filter medium can be operated with reduced pre-cleaning pressure; significantly lower operating costs thus significantly increase energy efficiency. Like the classic sinter-plate filter, the filter medium is absolutely fiber-free and thus ideal for contamination-free material recovery.

Extensive development work by Herding's own R&D department has resulted in extensive pilot phases in various application areas with diverse types of filter systems in which the Herding BETA has been put through its paces. Examples include various dryer applications, biomass incineration plants, extraction from rotary kilns, glass tank dedusting and high-temperature filtration behind mill systems.
