TRM Filter d.o.o.

Single stage secondary safety filter following the dust collector in critical applications. Also used as stand alone passive filtration of HEPA and ULPA grades usually in multiple stages.
High efficiency filtration with HEPA and ULPA filter elements. Available from dissipative media to conform ATEX requirements. Monitored by differential pressure gauge, switch or transmitter.
Safe-guarded by measurements at test ports for integrity testing by DOP/DEHS.
Optionally built to advanced hygienic standards from various stainless steel grades including surface finishing (mirror polished). 
Adapted to containment requirements by fully welded construction and Bag-in/Bag-out contact free filter exchange in conjunction with WIP provisions (optional).
Customized versions for OEMs.

Perfect filter cleaning for minimal energy cost and long filter cartridge life simply requires that a filter element is cleaned as often as necessary, as seldom as possible, as soon as the differential pressure increases beyond the best performance point and to an extent that prevents dust from migrating into the filter media. Managing these objectives in the cleaning step is a bit more difficult.
None of the optimal parameters of such a perfect filter cleaning operation are known in advance, moreover they are not stable overtime. TRM Filter has pioneered its Rotatronic Control, Smart Filter Cleaning control system:

• Pro-active filter cleaning, before the differential pressure has evolved beyond recovery from dust migration into the media
• Just-in-time filter cleaning
• Predictable filter life time by tracking the operating optimum and rest point after cleaning

Early Call to replace filter elements as their performance deterrence is foreseen

Explosion-pressure-resistant dust collectors are built such that an explosion even of the solvent fraction in hybrid mixtures - where these are included in the intended use - can only occurr on the raw gas side. While the raw gas side is decoupled from the upstream process during filter cleaning, an explosion expands through the filter media to the clean gas side. The volume there serves to equilibrate pressure below the Pwithstand of filter housing while the flame is arrested in the filter media. Filter media are considered safety components subject to ATEX approval. This design principle is implemented with the ECR Total Pharma Dust Collector and the ECH Occupational Hygiene Dust Collector for organic dusts and hybrids. The ECB dust collector for difficult dusts is suited to handle all organic dusts in this fashion.

Safe and reliable containment in OSD manufacture as well as powder handling with the ECH Occupational Hygiene Dedusting Filters is readily available to you. Systems are built in economic containment configurations that are designed in a staged response to the requirements for precise & reliable containment. These configurations embrace a specific recommendable functional scope beyond containment provisions.

Safety is designed into the ECH Occupational Hygiene Dedusting Filters: Their reliable and precise containment is defined from the applications' risk-based hygiene design targets.

Continuous dedusting operations, avoidance of batch- to-batch carry-over, loss prevention of dusts are some of the operational specifics that are mostly intertwined with specific hygiene target levels.

With five economic containment configurations the ECH filters are marrying precise and reliable economic system designs with operating functionality in as simple and economic a risk-adjusted design as conclusive.

ECR Total Pharma Dust Collector designed for ultimate safety in process dedusting. Explosion pressure resistant with all organic dust classes and hybrid mixtures.. Designed for containment up to OEB 5 in precise and reliable risk-based staged product lines. It performs with unmatched reliability in a threesome of best Rotatronic Mechanics filter cleaning, best Rotatronic Control of optimal cleaning procedures and timing, and economic surface filtration on dissipative membranes.
