HVAC & Chillers.
Power electronics built for the refrigeration cycle.
Co-designed motor drives and active front end inverters for compressor-driven HVAC and chiller systems — 50 kW to 500 kW. IEEE 519 compliance built in. Refrigerant-cooled power electronics. Targeting Daikin, Carrier, Trane, Johnson Controls, and XNRGY.
Why incumbent drives fail
chiller OEMs.
Danfoss FC102 and ABB ACS880 are general-purpose variable frequency drives adapted for chiller use. They are not co-designed with the refrigeration cycle. They require external harmonic filters. They cannot be refrigerant-cooled. They cost 40–60% more than a purpose-built India-manufactured alternative. Power Flux AI designs the drive and the Active Front End as one integrated system — no external filters, refrigerant-cooled power stage, THDi <3% built in.
"The founder spent years at Daikin Applied Americas designing exactly these systems — 500 kW air-cooled and 1 MW water-cooled chillers. We have lived this problem. We know where the incumbent solutions fall short."
Purpose-built for
this industry.
SiC Compressor Drive
Full-stack SiC inverter for centrifugal and scroll compressor drives. 40 kHz switching for minimum filter size. Refrigerant-cooled cold plate integrated with the compressor circuit. AI-FOC control with adaptive derating.
Active Front End — Integrated
AFE co-designed with the drive as one system. THDi <3% at rated load. No external harmonic filter. Bidirectional power flow for heat recovery applications. IEEE 519-2014 and IEC 61000-3-12 compliant by design.
HVLS Fan & Pump Drives
Purpose-built drives for condenser fans, cooling tower fans, and chilled water pumps. HVLS fan platforms up to 300 Nm direct drive — based on the world's first 300 Nm HVLS fan platform developed by the founder.
IEEE 519 & Safety
Automated IEEE 519-2014 harmonic compliance from the first design iteration. UL 61800-5-1 safety compliance support. IEC 62477 and CE marking support for international OEM programs.
Refrigerant-Cooled Power Stage
Power electronics enclosure and cold plate designed to integrate directly with R-410A, R-32, R-134a, or R-290 refrigerant circuits. Eliminates secondary cooling loop, reduces system complexity and footprint.
Predictive Maintenance Ready
Digital twin deployed with every unit. Compressor health monitoring, bearing fault detection, power quality trending, and efficiency degradation alerts. Python + InfluxDB + cloud IoT.
