VFD for Compressors: Selection Guide
How to select and size a VFD for screw, reciprocating and centrifugal compressors, covering overload rating, turndown limits and energy savings.
Schneider Electric ATV630C11N4 Altivar Process ATV630 VFD, 110 kW normal duty, 380-480V 3-phase, IP00.
The Schneider Electric ATV630C11N4 variable speed drive is an Altivar Process ATV630 unit rated 110 kW normal duty (90 kW heavy duty), delivering 211 A continuous output current at 2.5 kHz from a 380-480 V three-phase supply. It feeds 3-phase asynchronous and synchronous motors and mounts as an IP00 wall-mount unit for water and wastewater, mining and minerals, oil and gas, and food and beverage process applications.
Pick the normal-duty rating when the load is variable-torque (fan, pump, compressor) and only needs the standard 120% overload; the heavy-duty rating trades continuous current for the deeper 150% overload constant-torque loads such as conveyors and mixers need. It shares its mounting frame and IP rating with the adjacent kW steps in the ATV630 lineup, so the choice between them comes down to the motor's continuous current draw rather than the enclosure.
Schneider lists this Altivar Process ATV630 rating for water and wastewater pumps, screw and centrifugal compressors, conveyors and mixers, mining and minerals fans and pumps, oil and gas electro-submersible and jet-fuel pumps, and food and beverage pumps and fans.
