Data centers are the backbone of modern business — a single hour of downtime costs an average of $300,000 to $1 million. Yet 70% of data center outages are caused by human error, often from missed maintenance checks on cooling, power, or fire suppression systems. Oxmaint’s predictive AI maintenance platform automates every checklist item, schedules recurring inspections, and alerts your team before a failure happens — or book a 30‑min demo to see how we keep data centers running at 99.999% uptime.

Automate Every Data Center PM Task
Oxmaint schedules filter changes, battery tests, thermal scans, and fire system checks — and escalates anomalies to work orders instantly. No more missed intervals.
“The data centers that survive outages are not the ones with the most redundant equipment — they are the ones with the most disciplined maintenance programs. I have seen Tier IV facilities fail because a CRAC filter clogged and went unnoticed for three months. A digital checklist with automated reminders and photo evidence is not optional anymore — it is the difference between 99.999% and an insurance claim.”

Frequently Asked Questions
What is the most critical maintenance task for a data center UPS?
The most critical task is annual load bank testing at 80% of rated capacity for 30 minutes — this verifies battery strings deliver full power under load and identifies weak cells before they cause a transfer failure. Quarterly terminal torque and corrosion checks are also essential to prevent thermal runaway. Oxmaint schedules both tests and logs results automatically against each UPS asset.
How often should data center CRAC filters be changed?
MERV‑8 or MERV‑11 filters in typical data center CRAC units should be inspected monthly and changed every 90 days. High‑particulate environments (near construction, urban dust) may require 60‑day changes. Filter pressure drop monitoring is the best indicator — change when differential pressure increases by 150% over clean baseline. Book a demo to see how Oxmaint tracks filter life and auto‑orders replacements.
What is the acceptable temperature and humidity range for a Tier III data center?
ASHRAE TC 9.9 recommends a temperature range of 18–27°C (64–81°F) and relative humidity of 20–80% (dew point limited to 5.5–15°C). For high‑density zones, keep hot aisle at ≤35°C. Environmental sensors should be calibrated quarterly to maintain ±0.5°C accuracy. Oxmaint’s sensor integration alerts you immediately when thresholds are exceeded.
How does Oxmaint help prevent human error during maintenance?
Oxmaint enforces step‑by‑step digital checklists with mandatory photo uploads and signature sign‑off for each critical task (e.g., UPS bypass before battery work). It also blocks work orders if prerequisite permits or lockout‑tagout steps are incomplete. This reduces human error by up to 70% in documented case studies. See a live demo of the human‑error prevention workflow.
