_ Preventive maintenance checklist
Ten minutes now. Or a shutdown later.
25 checks that catch a chiller fault before it turns into a Sunday call-out. Instruments, limits and intervals already worked out for you.

A chiller doesn't stop out of the blue
It stops after weeks of numbers that were already telling you something. Nobody was reading them the same way, or reading them at all.
_ What's inside
Your inspection round, already planned
Checks in 5 areas
Power draw, condenser, temperatures, alarms, safety valve seals: where a fault starts long before anyone hears it.
What to measure, and where the limit is
Each check comes with the instrument to use and the value that should worry you. Numbers, not vague instructions.
Intervals already set
Weekly, monthly, six-monthly, yearly. Your whole preventive plan on one A4 sheet: what to do, and when.
Made for the plant room, not the filing cabinet
Big type, tick boxes you can fill in with a pen. Works on paper or on a tablet, offline, no sign-up.
_ Why it works
What changes after the first visit
You see the fault weeks earlier
Head pressure creeping up, COP creeping down, an alarm that keeps coming back: you catch the numbers before the chiller stops.
Fewer out-of-hours call-outs
An emergency call-out on a chiller costs many times more than a scheduled check, and that's before you count the product at risk.
Readings you can actually compare
Everyone works through the same 25 items with the same limits. Put March next to September and the trend is right there.

_ FAQ
What people ask us before they download it
Is it really free? Even if we're not a Tecnofreddo customer? +
Yes. It's the same checklist we use with our own customers; we've simply opened it up to anyone who works with industrial refrigeration. No cost, no sales call. If you ever need a hand with a chiller, you'll know where to find us.
Is it only for chillers, or for other refrigeration machines too? +
It's written for vapour-compression chillers with screw or scroll compressors. The same checks (evaporating and condensing temperatures, superheat, subcooling, current draw) apply to multi-compressor units and water-to-water machines. On transcritical CO₂ and ammonia some of the limits are different.
How long does it take to go through on the machine? +
Eight to twelve minutes per chiller, once you know where to find each parameter on the controller. Allow twenty the first time, while you get your bearings on the machine.
Can I share it with my team or my service contractors? +
Yes, go ahead. Print it, put it in your CMMS, attach it to the service report. The only thing we ask is that you don't resell it.
Will you see the next shutdown coming?
Get it now and do your first inspection this afternoon.
