Why Choose Super Royal?
What actually matters when you put this on your line
Automated Operation
Reduces manual switching and operator error by handling the start-up sequence on its own.
Digital Monitoring
A digital display and settings make it easier to read status and adjust cut-offs without repeatedly opening the panel.
Wide HP Range
Covers 1 - 3 HP, so one series can standardise across multiple motor sizes on site.
Built for Industrial & Pump Applications
Designed for the duty cycles seen in pumps, compressors, HVAC systems and general industrial motor loads.
Custom Panel Manufacturing Support
Subtech can adapt enclosure size, ratings and add-ons to project-specific requirements on request.
Rust-Resistant, Field-Ready Enclosure
Powder-coated GI/GPSP enclosures are built for Indian site conditions — dusty factory floors, outdoor pump houses and agricultural sheds alike.
