At Mainstream Fluid and Air, innovation is at the core of everything we do—and now, we’re bringing that innovation to cooling towers.
We’re proud to introduce our newest offering: Cooling Tower Fan Arrays featuring PMEC (Permanent Magnet Electronically Commutated) technology. Designed to replace traditional large single AC fans, our PMEC fan arrays provide significant energy savings, lower maintenance, and superior performance for facilities of all sizes.
Why Upgrade Your Cooling Tower Fans?
Traditional cooling tower AC fans are notoriously hard to maintain. Their location, height, and sheer size make routine service a challenge, often requiring costly downtime and specialized access equipment.
Mainstream’s PMEC fan array system offers a smarter solution:
Smaller, modular fans are easier to install and service.
Redundancy is built-in, so if one fan goes down, your system keeps running.
Energy efficiency is drastically improved, reducing operating costs over time.
Ideal for Facilities Ranging from 10 to 1000 Tons
Whether you manage a small commercial building or a massive industrial site, our cooling tower upgrades scale to your needs. Our fan arrays support capacities from 10 to 1000 tons, making them a versatile, future-proof investment.
Benefits of Mainstream’s PMEC Fan Array System
High Efficiency – PMEC motors offer industry-leading performance and energy savings. Low Noise & Vibration – A quieter, smoother-running system means better working conditions and less wear and tear. Built-in Redundancy – No more single points of failure. Multiple fans keep your system operational even during maintenance or failure. Easy Installation – Modular design and smaller components mean quicker, easier installs—often without the need for a crane.
