We configure and manufacture customized axial impellers configured to suit your application from 40 different blade profiles and 37 hubs. We have over 60 years of experience solving the most challenging targets of fan noise reduction and efficiency improvement.
Our modular impellers are very versatile – designed to allow blade geometry, number of blades, material, pitch angle, rotation direction and diameter variations/combinations to be finely adjusted to perfectly suit any HVAC/R or off-highway engine cooling application.
pmax, our newest impellers for high pressure powertrain cooling
Increase the Limiting Ambient Temperature and improve the available engine power for essential machine functions and reduce noise emissions with our PMAX fans from 446 mm up to 2438 mm (17.5 – 96 inch). Our new PMAX range of high pressure Off-Highway engine cooling impellers offers significant noise reduction, lower power consumption and higher airflow in harsh environments. The special blade geometry copes well with poor inlet and outlet flow conditions in cramped mobile and stationary radiator applications.
We offer 40 different blade geometries and 37 hub types to match the optimum shape with your airflow, pressure, rotation speed, temperature and other application specific parameters. Configuring a fan with the proper blade geometry optimizes airflow, lowers noise and improves efficiency.
materially significant
Each application calls for different combinations of materials. Our three thermoplastic materials and two aluminium alloys cover applications from low-pressure livestock ventilation to smoke extraction fans covering a temperature range from -40 to 400°C (-40 to 752 °F).
pitch: perfect
Our modular axial fans can be configured and assembled with a wide range of blade pitch angles ensuring the optimum efficiency is achieved at your required duty point. The width of the fan can be tailored to fit into your available installation envelope by adjusting the pitch.
whatever way you spin
Most of our blade profiles are available in both left- and right-hand turning versions for maximum flexibility in pusher (blowing) or puller (suction) applications.
let's BE HONEST: SIZE MATTERS
Our impellers are used in applications ranging in size from 200 mm (7.8”) electric motor cooling fans to 1250 mm (49.2”) cooling tower fans and 2438 mm generator cooling fans, suppling emergency power to critical infrastructure. Each of our profiles can be cut in 1 mm (0.039”) steps to perfectly fit the diameter of your application.
How to make a great impeller even better
For maximum functionality, we offer these add-ons for personalized use just for you.
Clutch
EPS
Winglets
Adding a viscous clutch to an impeller brings speed modulation, reduced fuel consumption and lower noise.
Flexible fan blade extensions reduce noise and improve efficiency by minimizing the tip clearance.
Winglets reduce blade tip vortexes and minimize fan noise.
