FDA 21 CFR Part 11-ready signoffs for pharma reactors and filling lines
Pharmaceutical and life-sciences plants run under the most demanding compliance regime in manufacturing. Every batch, every signoff, every deviation has to be reproducible years after the fact. Haltless monitors reactors, fermenters, lyophilizers, and filling lines, opens CMMS work orders against the same audit chain that signs every action with HMAC-SHA256, and gives quality assurance a reproducible trail that holds up under FDA 21 CFR Part 11 review.
EQUIPMENT WE MONITOR
Four asset families that ship with day-one connector support. No proprietary sensors, no custom integration sprint.
Stainless-steel reactors and bioreactors tracked through jacket temperature, agitator current, and pH and DO probe trends over OPC UA.
Shelf temperature, condenser pressure, and vacuum loops monitored continuously across a 72-hour freeze-drying cycle.
Vial fillers, peristaltic pumps, and capping stations tracked through fill weight, cycle time, and capper torque.
Sterilization F0 calculations, autoclave chamber pressure, and CIP caustic and acid concentrations logged for batch records.
FAILURE MODES WE CATCH
Three deterministic detectors run in parallel against every reading. These are the failure modes they tend to flag early in this industry.
Slow z-score drift on temperature, pH, and DO probes caught before a deviation triggers a batch investigation.
Rate-of-change on vacuum pressure flags pump or valve degradation hours before the cycle is at risk.
EWMA-tracked fill-weight drift and capper-torque excursions caught before downstream QC rejects the batch.
INDUSTRY CONTEXT
Quality assurance teams in pharma need every action signed, every signal traceable, and every CMMS work order tied to a regulator-readable batch record. Haltless provides the SHA-256 signoff over canonical payload that FDA 21 CFR Part 11 expects, the HMAC-SHA256 audit chain SOC 2 controls anticipate, and an explainable health score that a quality auditor can reproduce on paper. Customer remains responsible for system validation.
Vibration, thermal, and current signatures flagged before they cascade into a stoppage.
A 40MB Python agent runs on any Linux box next to your existing PLCs. No new sensors required.
Open APIs and pre-built connectors for SAP, Maximo, ServiceNow, and Jira route alerts straight into work orders.
Connect Haltless to your existing PLCs, validate the explainable health score on your own equipment, and we come back with a tailored quote. No new hardware, no proprietary sensors, no consultants.
COMMON QUESTIONS
Compliance is something your validation establishes, not something a vendor asserts. What Haltless supplies is the §11.10(e) evidence: every action attributable, contemporaneous, original, accurate and time-stamped, signed into a chain your auditor can verify offline.
Every score change, alert and work-order signoff carries an actor, a timestamp and a chained signature, retained 2,555 days. That is the data-integrity trail Annex 11 expects. Mapping it onto your batch records is part of your own validation work.
It reads and does not write. No control action, no setpoint change, no path back into the process. That keeps it outside the control-system validation envelope and out of IEC 61511 safety scope by design.
