Do you work with DeltaV?

Yes, DeltaV is part of our chemistry stack. Our partner Eric Rouane has 20+ years on this system, mainly in pharma and fine chemistry.

Do you have SIL analysis and safety modification experience?

Yes, we work jointly with your HSE and process engineering to validate the SIL impact of any change. HAZOP, LOPA documentation and SIL tests included in the deliverable.

Fine chemistry — batch reactors, safety, MES

Fine chemistry: modernizing without breaking the run.

Automation reinforcement for fine chemistry and specialty producers in Switzerland. ISA-88 batch reactors, MES integration, SIL2/SIL3 functional safety, PCS7 migration. Proven experience at Sun Chemicals and Swiss industrials.

Field reality

Chemistry-specific challenges

SIL functional safety: critical loops (reactors, ESD valves) must comply with IEC 61508/61511. Any change impacts SIL analysis and HAZOP documentation.

ISA-88 batch reactors: complex recipes, per-product parameterization, material traceability. Poorly designed S88 architecture = major technical debt.

Legacy PCS7 / DeltaV migration: moving from v7/v8 to v9 on in-service reactors requires a rigorous plan to avoid production loss.

Ex / ATEX zones: interventions in explosive atmospheres require certified equipment and specific procedures.

Our method

Our chemistry approach

We combine PLC/DCS expertise with process constraint understanding. For safety modifications, we work closely with your process engineering and HSE to validate SIL impact before intervention. For PCS7 migrations, we propose a phased plan with runbooks and maintenance windows.

Our services for this sector

Industrial automation

Vanguard Systems core business: multi-vendor industrial automation engineering (Siemens, Rockwell, Beckhoff, Emerson) on pharma, biotech, microtechnology, food & beverage and OEM sites in French-speaking Switzerland. 10+ years of field experience in regulated (GMP, GAMP5) and non-regulated environments. From design to commissioning, operations support, retrofit and migration.

Qualification and validation (CQV)

Complete support for qualification and validation in GMP environments: Factory Acceptance Test, Site Acceptance Test, installation, operational and performance qualification. GAMP5 and 21 CFR Part 11 compliant documentation, deviation management, support for Big Pharma internal audits and authority inspections. For missions requiring dual batch and CSV expertise, we work with our partner Eric Rouane (20+ years pharma CQV).

Industrial Data and AI

Practical application of data and AI to real industrial problems: process optimization, predictive maintenance, RPA on repetitive quality or maintenance tasks, technical chatbots on documentation and failure history. Pragmatic approach, no experimental demos: everything we deploy must work in operation and survive a quality audit.

Frequently asked

Frequently asked — fine chemistry

Yes. We routinely work with PCS7 v6/v7, knowing the limits (Windows compatibility, end-of-life Siemens support). For v9 migration, phased plan with rollback ready.
