Free fan bank assessment.
Send us what you've got on your air cooler fans. We'll tell you what's worth doing and what isn't, in writing, before anybody talks about a quote.
Every assessment is reviewed by Nick Agius, who designed the DG-II Anti-Rotation Device and holds its patents, and who introduced the elliptical inlet bell to the air cooler aftermarket. He has published on Air Cooled Heat Exchanger optimization in Hydrocarbon Processing.
Russell De Jesus, P.Eng, registered with APEGA, works the fan re-rate and the drive side. If a recommendation needs engineering behind it, it gets it.
We have told operators not to buy from us, because the part they were asking about would not have helped their unit. An assessment that finds nothing wrong is a useful result, and it costs you the same as the other kind.
Three steps, about a week.
- Tell us what you're running. Make, model, fan diameter, motor size, and the tag number if you have it. The OEM spec sheet is the single most useful thing you can send. Photos of the drive and the fan ring help too.
- We work the fan, not the brochure. We re-rate it at your conditions, summer and winter, and look at the whole drive rather than the one part that got your attention. Winter is where the surprises are. A fan sized on a summer day can sit close to its motor limit at minus forty.
- You get it in writing. What we'd change, what we'd leave alone, what it would cost, and what it buys you. If there's nothing worth doing, that's what the answer says.
What we look at
- Blade pitch, and whether the fan is still doing what it was sized for
- Obsolete blades, and what actually drops onto the same hub
- Motor shaft load at winter design temperature, not just summer
- Belts, sheaves, bearings and drive alignment
- Fans windmilling backwards when a motor is off
- Air losses at the blade tips, and hot air recirculating back through
- Whether the unit has simply been asked to do more than it was built for
Oil and gas, petrochemical and power sites running Air Cooled Heat Exchangers, Air Cooled Condensers or cooling towers. Anywhere from a two fan transmission station to a few hundred bays across a plant. Turnaround planning is a good time to ask.
Nothing. There's no obligation to buy anything at the end of it, and we are not going to put you on a call list.
Tell us what's going on.
The more you can give us up front, the more useful the first answer is. If you only know the site and that something isn't right, send that.
