Food Plant Compressed Gas and Nitrogen System Maintenance

OxMaint nitrogen generator work orders include daily purity reading fields where technicians record oxygen analyzer output as a percentage. Each reading is timestamped and stored against the generator asset record — building a continuous purity trend log over weeks and months. When readings trend toward your configured alert threshold (typically 0.2–0.3% above minimum specification), an alert fires to the maintenance manager before the purity failure affects production. The complete purity history is exportable as a PDF or Excel report for retailer MAP compliance audits and food safety certification reviews. See purity trend tracking in a free trial account

Yes. Compressor oil change work orders in OxMaint include fields for food-grade lubricant product name, batch number, certification standard (NSF H1, NSF 3H, or H2 as applicable), and supplier certificate upload. When the oil change is completed, the technician attaches the lubricant certificate and records the quantity used. This creates an auditable food-grade lubricant record tied to each oil change event — satisfying BRC clause 4.7.3 food-grade lubricant requirements and FSMA preventive control documentation for maintenance-related food safety hazards. Lubricant certificate expiry tracking prevents use of expired certifications.

OxMaint distribution system PM work orders include pressure drop measurement fields at key points across the distribution network — compressor outlet, main header, branch manifolds, and individual use points. Technicians record actual vs. expected pressure at each point during weekly surveys. The system compares readings against baseline values established during commissioning and flags pressure differentials exceeding threshold. Leak locations identified by large pressure drops between adjacent measurement points narrow the investigation area from the entire distribution network to a specific pipe section.

Yes. Gas analyzer calibration work orders in OxMaint capture calibration date, technician name, reference gas details (supplier, certificate number, expiry), pre-calibration reading, post-calibration reading, and pass/fail result. Calibration certificates are uploaded as attachments. HACCP plans that cite gas purity monitoring as a preventive control require documented evidence of regular calibration with traceable standards — OxMaint generates this evidence automatically from the work order completion record. Calibration interval alerts ensure no analyzer exceeds its scheduled recertification date without a work order being issued.
