Cryogenic Plant & ASU Reliability Review
We review agreed air separation unit (ASU) and cryogenic-plant operating trends and event history on a scheduled basis, looking for changes that deserve investigation. Findings become a watch list for your team. The retainer is scheduled review and agreed hours, not uninterrupted coverage. Some failures have no visible warning in the available data, and the review records those limits.
inquiries@cryobrothers.com. Thirty minutes, no charge. You leave knowing whether we can help and what a scoped engagement would look like.
Read about our cryogenic operating experience or discuss your plant and the scope of a review.
We get called when
- Repeat failures with no trend owner
- Nobody reviewing the plant between events
- Deferred work with no risk ranking
- A team that only calls consultants in emergencies
- Recurring trips closed out without a root cause
What you get
- Recurring review call on a fixed cadence
- Watch list grouped by failure mode, with observations and actions for shift supervisors
- Escalation path to the founders
- Quarterly written summary for leadership
Engagement details
How the review works
Make trend review a scheduled part of plant support.
Set the cadence
Agree the review frequency with your team based on the operating changes, event history, and data available.
Review the same signals every time
A short fixed set: approach temperatures, pressure drop between derimes, trip counts by mechanism. Consistency is what makes a small change visible.
Hand the shift a watch list
A focused list of observations, checks, and follow-up actions, with owners agreed with your team.
Where this comes up
Related industries and processes.
How the work is measured
Measures used to assess the work.
Findings from the prior review, closed with named owners before the next one.
Deviations documented with an owner and a follow-up decision.
Whether unplanned events were preceded by something somebody wrote down.
Why consider a review
A running plant still needs time set aside for performance and reliability review.
Day-to-day operating demands can leave recurring deviations without an owner. Scheduled review makes those observations, evidence gaps, and follow-up decisions visible.
This can complement the condition monitoring and maintenance work your team already performs. We agree which operating questions need additional review and avoid duplicating work that is already covered.

Common questions
Questions we get before the first call.
Not on the list? Email inquiries@cryobrothers.com and ask it directly.
How is this different from our PM program?
Some sites already do condition-based work. We agree how this review complements the maintenance program by looking at process trends, interactions, and recurring deviations across the facility. Existing maintenance and monitoring responsibilities stay with your team.
What cadence makes sense?
The cadence is agreed for your plant. Stable operation, changing conditions, and a recent event may each call for a different review frequency; the introductory call establishes what is useful and practical.
We only bring people in for emergencies.
A recurring review provides a scheduled opportunity to discuss developing questions and close earlier findings. It is separate from an urgent investigation and does not replace the site's operating or escalation arrangements. Availability is the agreed cadence and hours, not uninterrupted coverage.
Do you need access to our historian?
Exports are fine. We are not asking to sit inside your network. A routine data pull for the tags we agree on is enough.
What does the historian show in the weeks before a cold box derime?
It may show a change in pressure drop or approach temperature, depending on the event and the records available. We identify the signals supported by the data and record when no useful warning is visible.
Does the review cover trip investigation?
It covers the trip record. We group trips since the previous review by mechanism and identify which ones were preceded by a visible change in the trends. When a recurring trip needs a full root-cause investigation, we say so and agree that scope separately.
