Herding Filter

Dust collectors have a wide range of applications, and every process industry is using dust collectors in some form or other. Indpro in association with Herding GmbH are pleased to offer a revolutionary sintered plate filter element-based pulse jet filter used to separate dust particulates from fugitive dust emitting sources & process off gas. This filter ensures specialized filtration technology which provides better performance in terms of lesser emissions & longer element life as compared to traditional filters.

Herding dust collecting systems have special designs to protect personnel and machinery. They help protect the environment and recover valuable material from the process.

These special patented sinter-plate filter media and complete standard systems or customized solutions are manufactured in Herding, Germany. The hot gas filter media and systems cover a temperature range of up to 450° C. The maximum pressure range for process filters can extend from vacuum to a pressure of 10 bar(g). Special solutions for hazardous dusts and gases are available depending on the application.

Depending on the requirements, our system solutions start with collection of the dust and end with its removal. A suitable controller rounds out such a system solution into a fully automatic and low-maintenance solution, particularly since the filter media have an extremely long service life. These elements are ideal for product recovery due to their nature of filtration. There is no contamination that passes from filters to the dust being recovered.

Our products are supplemented by a wide range of accessories such as automatic pre-coaters to ensure that our systems run without problems. Extensive services including trainings for our customers' service and maintenance crews complete our range of products.
