Chiller & Pump Fleet Assessment
& Refurbishment Rotation Program
When your facility depends on multiple cryochillers, cryopumps, diffusion pumps, compressors, cold heads, and high-vacuum pumping assets, waiting for the next failure is expensive. YTI assesses your fleet, identifies risk, prioritizes critical equipment, and builds a staged refurbishment rotation plan so production teams can reduce surprise downtime, extend equipment life, and keep backup capacity ready before a system goes down.
A smarter way to manage aging vacuum assets
Turn emergency repairs into a planned refurbishment rotation
Cryogenic and high-vacuum equipment often fails in patterns. A cold head starts taking longer to reach temperature. A compressor develops pressure issues. A cryopump regenerates slower than it used to. A diffusion pump needs heater, jet, oil, or seal work. When those signs are tracked across a fleet, they become a maintenance plan instead of an emergency.
YTI’s fleet assessment and refurbishment rotation program helps facilities understand which chillers, pumps, compressors, cold heads, and vacuum components are healthy, which are declining, and which should be rebuilt first. The goal is to stage work around production, keep critical spares available, and move equipment through refurbishment before failure forces an unplanned shutdown.
If you have one failed unit right now, start with cryochiller & cryopump repair or diffusion pump refurbishment. If your facility has multiple systems and needs a larger plan, this fleet program is the better fit.
Chillers, pumps, compressors & cold heads
Equipment covered in a fleet assessment
YTI evaluates the cryogenic and high-vacuum assets that directly affect pump-down, base pressure, coating quality, uptime, and maintenance readiness. The assessment can be built around a single production line, a full facility, or multiple sites.
Cryochillers & Cryocoils
Polycold-style cryochillers, cryocoils, vapor traps, refrigeration circuits, refrigerant charge condition, cooling performance, and leak history reviewed for risk and rotation planning.
Cryopumps
Cryopump cooldown, base-pressure performance, regeneration behavior, array condition, contamination signs, and cold-head health assessed across the fleet.
Cold Heads
Cold-head runtime, displacer wear indicators, seal condition, valve performance, cooldown time, vibration, and rebuild priority documented for staged refurbishment.
Helium Compressors
Compressor operating condition, pressure behavior, adsorber service history, cooling, electrical condition, and spare readiness reviewed for cryogenic reliability.
Diffusion Pumps
Diffusion pump heaters, jets, oil condition, baffles, cold traps, backing performance, water lines, seals, and refurbishment timing assessed for production reliability.
Backing Pumps & Vacuum Hardware
Mechanical pumps, forelines, valves, gauges, traps, feedthroughs, refrigerant circuits, and critical vacuum hardware included when they affect pump-down or uptime.

Why fleet planning matters
Problems a refurbishment rotation program solves
Most facilities know which systems are critical, but not always which units are closest to failure. A fleet program creates visibility so maintenance and production teams can plan rebuilds before equipment failure dictates the schedule.
Surprise Downtime
Staged refurbishment reduces the risk of waiting until a cryochiller, cryopump, compressor, or diffusion pump fails during production.
No Clear Rebuild Priority
Fleet scoring helps identify which assets should be rebuilt first, which can wait, and which should be held as backup capacity.
Incomplete Asset Records
YTI helps document equipment, serial numbers, service history, observed condition, known failures, and recommended next actions.
Maintenance Budget Spikes
Rotating refurbishments across a planned schedule helps reduce the budget shock of multiple failures happening close together.
Wrong Spare Strategy
Fleet review identifies where spares, refurbished exchange units, stocked components, or backup assets make the biggest uptime impact.
Shutdown Planning Gaps
Recommended rebuilds, parts, testing, and service work can be aligned with scheduled shutdowns instead of rushed during a breakdown.
Assessment, scoring, planning & rotation
What the fleet program includes
The program can be sized for a few critical units or a full facility. YTI builds the scope around the equipment count, production risk, available spares, failure history, and how much downtime your operation can tolerate.
Asset Inventory
Document chillers, pumps, compressors, cold heads, nameplates, locations, service status, spares, model details, and known operating issues.
Condition Review
Assess cooldown performance, base pressure, pump-down behavior, regeneration times, compressor alarms, leaks, charge history, noise, vibration, contamination, and maintenance indicators.
Risk & Criticality Scoring
Rank each asset by production importance, condition, failure history, rebuild urgency, spare availability, and replacement difficulty.
Refurbishment Rotation Plan
Create a staged plan for which chillers, cryopumps, cold heads, compressors, and diffusion pumps should move through refurbishment first.
Critical Spares Planning
Recommend stocked parts, refurbished exchange units, backup components, refrigerants, heaters, seals, electronics, feedthroughs, and service kits where practical.
Reporting & Recommendations
Provide a clear summary of findings, recommended actions, refurbishment priorities, spare strategy, and service next steps for maintenance and production teams.
From asset list to rotation plan
How the fleet assessment works
Collect Fleet Data
Send equipment lists, photos, nameplates, system locations, production-critical assets, failure history, maintenance logs, and any known performance issues.
Assess Condition
YTI reviews the fleet remotely or on-site, checking symptoms, service history, operating behavior, known weak points, spares, and refurbishment candidates.
Prioritize & Plan
Each unit is ranked by risk, criticality, and rebuild urgency. Then we build a staged refurbishment rotation that fits your production and maintenance windows.
Refurbish & Repeat
Units move through depot refurbishment or on-site service in planned stages, with support for component stocking, emergency response, and ongoing fleet updates.
Fleet programs can be combined with on-site troubleshooting, depot refurbishment, emergency response, component stocking, cryogenic repair, diffusion pump rebuilds, and custom fabrication. See full service details →
