The pharmaceutical industry’s centre of gravity is shifting. High-potency active pharmaceutical ingredients (HPAPIs), antibody-drug conjugates, oncology injectables, and cell-therapy products now form the backbone of late-stage pipelines. Each of these categories presents the same dual challenge: nanogram-level operator exposure limits on one side, ISO 5 / Grade A sterility on the other, often within the same suite. In such a challenging environment, the process isolator has stopped being a piece of ancillary equipment and become the architectural centrepiece of the manufacturing floor.
Few suppliers have responded to that shift as comprehensively as Switzerland-based Dietrich Engineering Consultants. DEC Process Isolators are now deployed across pharma, biopharma, radiopharma, fine chemicals, and advanced-materials production worldwide, and the company’s portfolio is engineered to a single, deliberately provocative benchmark: “Are you ready for OEB 7?”
A Portfolio Built Around Process, Not Geometry
What distinguishes DEC Process Isolators from commodity glovebox suppliers is that the design conversation begins with the process, micronization, charging, dispensing, drying, sterility testing, or fill-finish, rather than with a generic enclosure to which the process is later fitted. The result is eight discrete isolator families, each SMEPAC-validated, each modular, and each available as rigid-wall configurations depending on the duty cycle and cleanability requirements.
MC DecJet®: The Flagship Micronizing Isolator
At the centre of the portfolio sits the patented MC DecJet® spiral jet mill, now in its fourth generation and offered in sizes from MC DecJet® 30 through MC DecJet® 500.
The MC DecJet® integrates micronization and containment in one engineered system, recognizing that isolator airflow and jet mill gas dynamics are interdependent. Treating them separately risks both particle-size control and containment integrity.
For pre-milling and lump-breaking duties, the patented UMS DecMill® can be integrated within the same isolator envelope alongside a co-mill, allowing operators to interchange milling technologies and MC DecJet® sizes without re-engineering the containment.
Charging Isolators and the PTS Powder Transfer System®
Reactor, blender, and dryer charging is where DEC Process Isolators have arguably reshaped facility design. Conventional practice forces the isolator to sit directly above the vessel, typically on a mezzanine, because gravity is doing the work. DEC eliminates that constraint through its proprietary PTS Powder Transfer System®, a dense-phase pneumatic conveyor that transfers material from a single ground-floor charging isolator to multiple vessels with no gas exchange between the isolator and the reactor.
The operational implications are significant: one dispensing point can serve several reactors, inertisation requirements are decoupled from the isolator, and multi-floor plant layouts can be radically simplified. The PTS principle also underpins DEC’s sterile charging solutions, where the same sealed transfer geometry preserves the sterility assurance level end-to-end.
Dispensing, Sampling, and the Isocharge Family
For dispensing and sampling, DEC offers a configurable platform with airlocks, Rapid Transfer Ports (RTPs), or drum-docking systems for material entry; multi-scale weighing with MES connectivity for recipe management; and integrated sieves or conical mills where the process demands. The Isocharge system enables high-containment discharge of multiple drums and bags at production speed, while Isotube is engineered for lumpy materials and the DCS® Drum Containment System addresses multi-drum campaigns with full containment from receipt to charging.
For sampling specifically, the rigid and flexible DCS® Sampling enclosures provide a smaller-footprint alternative to a full sampling isolator, a meaningful saving where floor space and qualification effort are both at a premium.
DEC Group’s containment platforms are designed to accommodate everything from laboratory containers and bags to standard production drums, typically including 5 L, 10 L, 20 L, 30 L, 50 L, 100 L, and 200 L formats through modular docking and transfer interfaces. This flexibility allows the same containment philosophy to scale from development to commercial manufacturing.
Filter Dryer and Vacuum Tray DecDryer Isolators
Downstream of the reactor, DEC’s double-chamber filter dryer isolators handle powder discharge, heel recovery, and contained pack-off into bags or drums. The system supports filter dryers from laboratory to multi-square-metre production scale, with CIP wash guns and rotating spray heads enabling fast turnaround between campaigns. For heat-sensitive APIs, the Vacuum Tray DecDryer operates under reduced pressure at gentler temperatures, protecting thermolabile compounds while remaining fully cGMP compliant in 316L stainless steel construction.
Aseptic, Cell Therapy, and Sterility Test Isolators
DEC’s aseptic portfolio is structured around three pillars. SteriPharm® standard isolators cover routine aseptic manufacturing in single or multi-chamber configurations. Custom-built aseptic isolators are co-engineered for complex biotech workflows, including antibody-drug conjugate production. Modular Cell Therapy Isolators (CTI) are positioned as a credible alternative to traditional cleanroom operation, delivering Grade A / ISO 5 conditions in a smaller footprint, with integrated incubators, centrifuges, and hydrogen peroxide decontamination, and without the operational overhead of full gowning.
Modular Sterility Test Isolators complete the aseptic line-up, with integration of Millipore Steritest and Sartorius Sterisart NF units, six-glove main chambers or half-suits, and recirculating laminar flow for unidirectional Grade A classification.
Nuclear Containment and the Walker Barrier Heritage
For radiopharmaceutical and nuclear applications, DEC operates through the Walker Barrier Systems brand, drawing on a 77-year engineering lineage in glovebox and hotcell manufacture. The Mauston, Wisconsin facility manufactures to NQA-1 quality standards in accordance with the ASME 2008–2009 Addenda, with leak-rate performance to 10⁻⁶ cc/sec at 4-inch water column per AGS-G006-2017. Walker Barrier’s reference list includes the world’s largest radiopharmaceutical hotcell isolator, a 70-foot installation producing Molybdenum-99, a radioisotope manufactured at only five sites globally.
DGT Pro: Closing the Glove Integrity Loop
No isolator is stronger than its weakest glove port. DEC’s DGT Pro wireless glove integrity tester detects micro-defects down to 100 µm, identifies individual gloves by RFID, maintains a full audit-trail test history, and complies with EU GMP Annex 1, ISO 14644-7 Annex 5, 21 CFR Part 11, and EU Annex 11, the four standards that effectively define modern isolator qualification.

For pharmaceutical engineers, project managers, and validation leads, currently looking for high-containment or aseptic capacity, the most efficient way to evaluate DEC Process Isolators is to see them operating in person. DEC Group will be exhibiting the full breadth of its isolator portfolio at the upcoming Pharma Pro & Pack show, with live demonstration units and technical specialists on hand to discuss specific process challenges, OEB classification questions, and integration scenarios.
Visitors can find the DEC Group team at Hall 1 | Booth C21, where the MC DecJet®, PTS Powder Transfer System®, SteriPharm®, and DGT Pro will all be available for hands-on inspection. Registration is open now, pharmaceutical manufacturers planning capital projects in the next 12–24 months are particularly encouraged to pre-book a technical consultation slot to avoid extended waits on the show floor.
The Strategic Read
Modern pharmaceutical manufacturing is converging on a single requirement: containment that does not compromise sterility, sterility that does not compromise containment, and modularity that allows both to scale with the molecule. DEC Process Isolators are engineered against precisely that brief, and the company’s combination of Swiss process engineering, American nuclear-grade fabrication, and an unusually deep accessory ecosystem, from PTS transfer to DGT glove testing, makes the portfolio worth a close look for any operator preparing for OEB 7-class molecules or aseptic biologics scale-up.
For a sector where a single cross-contamination event can erase a year of campaign output, that breadth is not a marketing claim. It is the brief.
