At 2:47 AM on a Tuesday, a blast freezer compressor at a Midwest meat-processing plant finally gave out after running with elevated head pressure for 23 days. The dashboard nobody was watching had been flagging the trend since the start of the month. The outcome: 18 hours of downtime, $34,000 in spoiled product, emergency parts shipping premiums, and an FDA inspector on site two days later asking to see temperature logs that did not exist in any organised form. Every cold-storage operator has a version of this story — or is about to. Start a free trial of OxMaint to put continuous refrigeration monitoring and PM scheduling in place this week, or book a demo to see how cold-chain operators catch failures 3–4 weeks before they happen.
OxMaint gives cold-storage and food-logistics operators continuous temperature visibility, automated PM schedules for every compressor, condenser, and evaporator, and audit-ready compliance records — all from a single platform that scales from one walk-in to a 4,500-sq-ft multi-zone facility.

One failed gasket. One missed inspection. One ruined pallet.
A $40 gasket replaced on schedule prevents a $22,000 temperature excursion. The platform that makes that discipline automatic pays for itself inside 90 days.
Why Cold Storage Is Uniquely Unforgiving — and Why CMMS Is the Answer
Cold storage has no tolerance for drift. A general-purpose warehouse can survive a 4°C temperature swing without consequence; a frozen-goods facility cannot. Product integrity, FSMA and FDA compliance, insurance coverage, and energy performance all depend on refrigeration systems holding setpoint 24 hours a day, every day, year after year. The operational challenge is that the systems most responsible for that performance — compressors, condensers, evaporators, expansion valves, defrost controllers — degrade gradually, silently, and almost always before anyone on the floor notices. A purpose-built CMMS closes that visibility gap by turning every sensor, every PM, every inspection, and every work order into a single connected record.

Zone 3 · Blast Freezer A
-31.2°C
Target: -32 to -35°C
TRENDING · Head pressure rising 4 days

Failed door gasket · Technician dispatched · ETA 42 min
The Failure Cascade: How Small Issues Become $50K Events
Stage 01
Day 0–3
Silent degradation begins
Condenser coils accumulate grease and debris. Head pressure creeps 3–5% above baseline. Invisible without sensor trending.
Cost to fix now: $80 (coil clean)
Stage 02
Day 4–10
Compressor strain
Amp draw rises. Oil temperature elevates. Motor works 15–20% harder to hold setpoint. Bearings begin accelerated wear.
Compressor seizure. Full zone excursion. Spoiled product, emergency labour premium, regulatory exposure, insurance dispute risk.
Cost to fix now: $34,000–$75,000
How OxMaint Runs Cold-Storage Maintenance End to End
Four capability clusters work together inside OxMaint to prevent every stage of the failure cascade above. Most operators see measurable PM compliance improvement inside the first 30 days. Start a free trial and configure your first refrigeration asset in under 10 minutes.
Continuous IoT Temperature Logging
Every zone, every shift, every excursion — logged automatically. Compare to FSMA thresholds in real time. No more monthly manual rounds.
Head Pressure & Amp Draw Trending
Early-warning analytics flag degrading compressors 2–4 weeks before failure. PM work orders auto-raised against the specific asset and technician.
PM Schedules Tied to Every Asset
Compressor oil service, condenser coil cleans, gasket inspections, defrost verification — all scheduled per IIAR guidelines and tracked automatically.
FSMA & FDA-Ready Audit Logs
Every temperature reading, corrective action, and PM event timestamped and signed. Export an audit report for any date range in under 5 minutes.
Refrigerant Leak & EPA Compliance
Leak checks, charge logs, and EPA Section 608 records maintained against every unit. Early alerts prevent $37,500-per-day chronic-leaker penalties.
Energy & Cost Analytics
Track kWh per zone, cost per pallet-day, and compressor runtime against baselines. Identify the 10% of assets driving 40% of energy spend.

Frequently Asked Questions
Does OxMaint work with our existing temperature sensors and SCADA?
Yes. OxMaint integrates with most common IoT temperature sensor brands, BMS systems, and SCADA platforms via API or direct connector. For heritage facilities or retrofits without existing sensors, LoRaWAN wireless sensors can be installed in 1–2 days per site with no cabling. Book a demo to review integration options for your setup.
How quickly can we generate FSMA / FDA compliance reports?
Under 5 minutes for any defined period. OxMaint exports continuous temperature records, excursion event logs, corrective-action trails, and full maintenance histories as PDF — formatted for FSMA, FDA 21 CFR Part 117, FSSAI, or your local regulator. Auditors can also be granted read-only portal access for live review.
What hardware costs are involved beyond the software?
For facilities without existing sensors, wireless IoT temperature probes typically cost $4,000–$9,000 for a mid-size cold-storage site depending on zone count. Facilities that already have sensors, SCADA, or a BMS usually pay zero additional hardware cost — OxMaint simply ingests the data. Start a free trial to validate your current data sources.
Is OxMaint a fit for small cold-storage operators or only large facilities?
Both. The platform scales from a single walk-in cooler running one compressor to a multi-zone 50,000+ sq ft cold-storage campus. Pricing is per-site with unlimited users, so small operators get the same PM automation, audit logs, and compliance tooling as enterprise chains — without enterprise pricing.
Every Degree of Drift Costs Money. OxMaint Holds the Line.
Continuous monitoring, data-driven PM, leak-proof compliance records, and compressor-saving early warnings — all in one platform purpose-built for cold-chain operators who cannot afford to be reactive.
