A reactor preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the reactor fails. This page gives the schedule used in the PlantOps360 task library for reactor (/ jacketed vessel with agitator), which follows common industry practice for general-purpose equipment. It is also searched for as jacketed vessel, glass lined reactor, SS reactor, batch reactor.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
Reactor preventive maintenance schedule and checklist
| How often | Task | Estimated time |
|---|---|---|
| Daily | Check batch records for temperature, pressure and agitator parameters; check for leaks at glands | 10 min |
| Weekly | Check agitator seal, gearbox oil and coolant or steam lines | 20 min |
| Monthly | Check relief and rupture disc status; check jacket and nozzle insulation | 45 min |
| Quarterly | Check agitator coupling, gearbox and motor current; check bearing condition | 90 min |
| Half-yearly | Inspect nozzles, gaskets and vessel internals during shutdown; check glass lining (if glass lined) | 180 min |
| Annual | Statutory pressure test or examination as required; overhaul agitator, seal and instruments; replace rupture discs as per the maker's interval | 600 min |
Reactor maintenance frequency and yearly workload
At the estimated times, one reactor needs about 109 hours of preventive maintenance a year. The biggest single job is “Statutory pressure test or examination as required; overhaul agitator, seal and instruments; replace rupture discs as per the maker's interval” at 600 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 1 | 10 min | 60.8 h |
| Weekly | 1 | 20 min | 17.3 h |
| Monthly | 1 | 45 min | 9.0 h |
| Quarterly | 1 | 90 min | 6.0 h |
| Half-yearly | 1 | 180 min | 6.0 h |
| Annual | 1 | 600 min | 10.0 h |
What goes wrong on a reactor without preventive maintenance
- Agitator seal leakage
- Jacket leaks and fouling
- Relief device faults
- Instrument drift on temperature and pressure
What to watch between services
- Temperature, pressure and agitator current
- Seal and gearbox condition
- Relief and rupture disc status
Safety and statutory notes for reactor maintenance
Reactors are pressure equipment with relief devices. Isolation, cleaning and vessel entry follow the permit and confined-space procedures of your site.

Run this reactor schedule in maintenance software
In preventive maintenance software, each row above becomes a recurring task on the asset with its checklist, time estimate and parts. Tasks can be triggered by calendar date, running hours, meter readings or production cycles, each completed task is recorded with the person and date, and a failed check can open a work order. For the method behind it, read the guide to the preventive maintenance schedule, or use the free generator to get a 12-month plan for your whole equipment list.

Frequently asked questions
How often should a reactor be serviced?
In our schedule a reactor has 6 tasks: 1 daily, 1 weekly, 1 monthly, 1 quarterly, 1 half-yearly, 1 annual. The biggest job is “Statutory pressure test or examination as required; overhaul agitator, seal and instruments; replace rupture discs as per the maker's interval”, which is done annual. Always follow the maker’s manual where it gives a different interval.
What is included in reactor preventive maintenance?
It covers routine checks and jobs such as “Check batch records for temperature, pressure and agitator parameters; check for leaks…”, “Check agitator seal, gearbox oil and coolant or steam lines”, “Check relief and rupture disc status; check jacket and nozzle insulation”, up to the annual overhaul or inspection. The full list with times is in the table above.
How many hours of maintenance does a reactor need per year?
About 109 hours per unit per year at the estimated times in our library, including the daily checks done every day. Use it to plan workload, not as a benchmark.
Is there a free reactor maintenance checklist?
Yes. The table on this page is a ready checklist. The free preventive maintenance schedule generator turns it into a 12-month Excel schedule for your list of equipment, with monthly workload hours.
