Don’t Send Your Technicians Out There.
There’s A Better Way.
Ditch the trips with our low-maintenance NEMA 3R enclosure for any VFD brand.
Do your technicians have to travel to remote areas servicing the AC units keeping your variable frequency drives (VFD) cool in your NEMA 3R enclosures? What if your enclosure didn’t need an AC unit? The Cates CoolDrive UL 508A/NEMA 3R Enclosure was specifically designed to dissipate heat and keep your drives cool without an air conditioner. CoolDrive 3R is affordable, can be configured with any brand that has a flange-mount drive, supports multiple door options, and offers quick delivery to get you up and running fast.
