Howden cooling fan parts
Howden builds axial cooling fans with fiberglass reinforced plastic (FRP) blades for air cooled heat exchangers, air cooled condensers and cooling towers, from 28 in to 48 ft. The SX is Howden's air cooler fan, the E and D series cover large towers and condensers, and the FPX is a small one piece fan. Fan-Div supplies replacement parts for Howden fans, and upgrades older fans to Howden's low noise designs where that makes sense.

A Howden upgrade in Alberta
On a 1960s cooler at an Alberta gas plant in 2024, our team upgraded the fans to Howden ultra low noise fans, with inlet bells, timing belts and DG-II Anti Rotation Devices®. After the turnaround the nearest resident noticed a big drop in noise, and the fans moved more air from the same motors. See the result.
How Howden builds its fans
Howden builds its cooling fans with fiberglass reinforced plastic (FRP) blades and polyurethane coated steel hubs. The standard operating range is -20°C to 65°C (-4°F to 149°F), extendable on request, and Howden's oil and gas literature rates its FRP fans for 500°F for 4 hours in a fire case. Howden tests fan performance to ISO 5801 and AMCA standards at its test rig in Hengelo, Netherlands.
