The long version of what we supply. Written for the people who have to keep the process from running hot.
Giant radiators for industrial plants. They pull heat out of your process with air blown across finned tubes. Air cooled condensers are the biggest of them all, dry process and 32 foot fans. We supply the parts and the optimization design that keep them running.

The big fans, typically 9 to 40 ft, on Air Cooled Condensers, Air Coolers and Cooling Towers. We're the exclusive Canadian distributor of the DG-II Anti-Rotation Device® and the global distributor of the E-Bell™. The DG-II stops fans windmilling backwards, which is a safety issue, not just a wear issue. The E-Bell™ is the world’s first fiberglass adjustable sectional elliptical inlet bell: it feeds the blade tips properly so the fan moves more air, it runs quieter, and its deep profile can help reduce how much hot exhaust short cycles back into the inlet, a persistent problem on SAGD sites and gas plants. See why fans windmill.
The water side of cooling, and home to some of the largest fans in the plant. We supply parts and components for Cooling Towers and Evaporative Systems, including BAC and Evapco units, so your water cooled equipment keeps running too.
When something wears out you don't want to wait weeks. Some parts we stock, some we source, and either way we get them to you fast, so a small fix doesn't turn into a big shutdown. See fan parts by brand.
Up to 9°C more cooling, and up to 3°C more from E-Bells™
High efficiency fan upgrade on engine coolers, sped up to 340 rpm, plus E-Bell™ inlet bells.
“Benefits are as high as a 9 degree C difference in cooling.”
Running above 30°C for the first time
Five fans across two trains converted from Moore to Cofimco, with inlet bells, tip seals and new longer fan rings.
“Our run time in hot weather is much better.”
No production cuts at 34°C
16 fans converted from low efficiency Moore to high efficiency Cofimco-Hudson, tip speed raised from 8,000 to 10,000 fpm, timing belts, inlet bells and DG-II Anti-Rotation Devices®.
“We did not have to cut production as the fans did their job this time.”
2 to 4°C better summer approach temperatures
New fans, inlet bells and tip sealing.
“Our trending indicates we got between 2C and 4C improvement on our approach temperatures in summer. So this was a win for us.”
97/98 dBA down to 78/84 dBA, with more airflow
New low noise Cofimco engine cooler fans on two compressor units.
“Both units are running great, noise reduction is night and day difference.”
“I was pretty surprised by how much air it moves… When I stood inside the new E-Bell with the fan running, the difference in airflow was really noticeable.”
“The inlet bells we installed fit up really well and we have noticed an improvement on cooling. We would like to install these on two other fans in our plant.”
“On a positive note, the resident nearest the plant noticed a huge difference in noise once we fired back up last September after the turnaround… Nice to know it's having a positive effect on the people in the surrounding area.”
“Initially, you could barely carry on a conversation and now you don't even need hearing protection. The transition from before and after is absolutely amazing!!”
“Thanks Nick! Been great working with you over the Years and look forward working with you in the future.”
Every Air Cooled Heat Exchanger moves ambient air across a finned tube bundle. The only question is which side of the bundle the fan sits on, and that one decision drives fan power, air distribution, recirculation and how easily you can reach the drive to service it.

The fan pushes ambient air up through the tubes. Fan, drive and motor sit under the bundle where you can reach them, and they run in cool air, so bearings and belts live longer. The fan handles denser air, so it takes less horsepower for the same duty. The trade is weaker air distribution across the bundle and a low exit velocity off the top, which invites hot air recirculation on a still day.
The fan pulls air through from above. Air distribution across the bundle is more even, exit velocity is roughly double, so recirculation drops off sharply, and the plenum shades the tubes from sun and hail. The trade is that the fan, belts and bearings sit in the hot exit air, it takes more horsepower for the same air mass, and the drive is up on the deck when it needs service.
Both arrangements are covered by API 661. Which one suits a given service depends on process temperature, plot space, and what the site can actually maintain. Talk to us about yours.
