TRM Filter d.o.o.

Single-stage secondary safety filter downstream of 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 with dissipative media to meet ATEX requirements. Monitored by differential pressure gages, switches or transmitters.
Assured by test port measurements for integrity testing by DOP /DEHS.
Optionally built to advanced hygiene standards from various grades of stainless steel including surface finish (mirror polished).
Adapted to containment requirements by fully welded construction and non-contact bag-in/bag-out filter change in conjunction with WIP devices (optional).
Customized versions for OEMs.

Perfect filter cleaning for minimum energy cost and long filter cartridge life simply requires that a filter element be cleaned as often as necessary and as infrequently as possible once the differential pressure rises beyond the point of best performance, and at a rate that prevents dust migration into the filter media. Achieving these goals in the cleaning phase is somewhat more difficult.
None of the optimal parameters of such perfect filter cleaning are known in advance; moreover, they are not stable over time. TRM Filter has pioneered this with its Rotatronic Control, Smart Filter Cleaning control system:

• Proactive filter cleaning before differential pressure has developed to the point where dust migration into the media cannot be reversed.
• Just-in-time filter cleaning
• Predictable filter life by tracking operating optimum and resting point after cleaning

Early call for filter element replacement as their performance degradation is predicted

Explosion-pressure-resistant dust collectors are constructed in such a way that an explosion, even of the solvent fraction in hybrid mixtures - if these are part of the intended use - can only occur on the raw gas side. While the raw gas side is decoupled from the upstream process during filter cleaning, an explosion spreads through the filter media to the clean gas side. The volume there serves to equalize the pressure below the P-values of the filter housing, while the flame is retained 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 suitable for treating all organic dusts in this way.

Safe and reliable containment in OSD production as well as powder handling with ECH Occupational Hygiene Dedusting Filters is readily available to you. Systems are built in economical containment configurations that are incrementally matched to the requirements for precise & reliable containment. These configurations include a specific recommended feature set that exceeds containment requirements.
Safety is provided in the ECH Occupational Hygiene Dedusting Filters: Their reliable and accurate containment is defined by the risk-based hygiene design goals of the applications.
Continuous dedusting operations, avoidance of batch carryover, prevention of dust loss are some of the operational features that are usually linked to specific hygiene objectives.
With five economical containment configurations, ECH filters combine precise and reliable economical system designs with operational functionality in the simplest and most economical risk-adjusted design possible.

The ECR Total Pharma dust collector is designed for the ultimate in process dust collection safety. Explosion pressure resistant for all organic dust classes and hybrid mixtures. Designed for containment up to OEB 5 in precise and reliable risk-based product lines. It operates with unsurpassed reliability in a trifecta of best Rotatronic® Mechanics filter cleaning, best Rotatronic® Control of optimal cleaning procedures and timing, and economical surface filtration on dissipative membranes.
