Applications — What Phoenix Phase Converters Power
Phase converters aren't a one-size-fits-all product. A 30 HP Haas CNC mill has very different power needs than a 7.5 HP air compressor or a 40 HP grain dryer. The wrong sizing means weak starts, hot motors, and expensive surprises.
Over 50 years of engineering experience means we've sized converters for nearly every industrial machine made. Pick your application below for sizing guidance, real customer examples, and the exact Phoenix unit that fits your shop.
⚙️
CNC Machines
Haas, Tormach, Bridgeport, Mazak, Fanuc, Siemens. Precision Balanced output stays within 3% leg-to-leg under load — well inside every modern VFD tolerance window.
Sizing for CNCs →🔧
Mills, Lathes & Drill Presses
The classic machine shop. Bridgeport mills, South Bend lathes, Wells-Index, Clausing, Sharp, Birmingham. Most shops do best with a 10–20 HP Phoenix unit.
Sizing for machine shops →💨
Air Compressors
Compressors are hard-starting loads — add 50% headroom to your nameplate HP. We size right the first time for Ingersoll-Rand, Quincy, Kaeser, Atlas Copco, Saylor-Beall.
Sizing for compressors →⚡
Welders & Plasma Cutters
Miller, Lincoln, Hypertherm, ESAB. Welders pull short, heavy current spikes. We help you choose between a dedicated unit and a shop-wide converter.
Sizing for welders →🪵
Woodshops
Planers, joiners, shapers, wide-belt sanders, dust collection. SCM, Felder, Powermatic, Northtech, General. Often 5–15 HP shops with one or two larger pieces of iron.
Sizing for woodshops →🔥
Kilns & Furnaces
Ceramic kilns, glass kilns, heat-treat furnaces, induction heaters. Steady resistive loads, simple sizing. Skutt, L&L, Olympic, Paragon, Cress.
Sizing for kilns →❄️
HVAC & Refrigeration
Walk-in coolers, ice plants, packaged rooftop units, large condenser fans. Commercial buyers running 7.5–50 HP three-phase compressors on single-phase service.
Sizing for HVAC →🌾
Farms & Agriculture
Grain dryers, irrigation pumps, milking parlors, hammer mills, feed augers. Off-grid or rural? You don't need the utility to bring in three-phase — Phoenix does it for less.
Sizing for farms →🚗
Auto Shops & Car Lifts
Two-post lifts, four-post lifts, alignment racks, tire machines, wheel balancers. Rotary, Bendpak, Challenger, Mohawk. Most auto shops fit on a 10 HP unit.
Sizing for auto shops →🏢
Elevators & Conveyors
Commercial freight elevators, dumbwaiters, conveyor systems. Continuous-duty operation, code-compliant builds, NEMA 4 enclosure standard.

Frequently asked across all applications
How do I know which application page applies to me?
If you have one dominant machine (a CNC, a compressor, a kiln), start with that page. If you're powering a whole shop with several different types of equipment, start with the page that matches your largest motor — that's the sizing driver. Or skip the reading and call us at 800-417-6568.
Can one Phoenix unit power my whole shop?
Yes. Size the converter to your largest motor plus 50% headroom, and most shops run their entire three-phase equipment list off a single Phoenix unit. We've sized one unit to run a CNC mill, a lathe, an air compressor, and a dust collector simultaneously.
What if my equipment isn't in the list above?
We've powered grain dryers, MRI compressors, ski-lift motors, brewery chillers, taxidermy freezers, theater stage lifts, even a synchrotron particle accelerator. Call us with the equipment nameplate HP and we'll size it.
Do you make different converters for different applications, or one for everything?
Same industrial chassis (NEMA 4 enclosure, TEFC cast-iron idler, lifetime-warrantied control panel) across every application. The difference is the configuration — Standard, AutoStart (kills standby load between jobs), or DualZone (cuts inrush in half for hard-starting machines). The application drives the configuration, not the build quality.
