National Vision protects precision manufacturing equipment with Torus

National Vision operates a 65,000-square-foot eyewear manufacturing and distribution facility in South Salt Lake, where 185 employees produce custom lenses for brands like America's Best and Eyeglass World. The plant manages the full lens design and manufacturing process — etching, coating, polishing, and mounting — using high-precision equipment that supports a nationwide retail network. But voltage swings of up to 15% were damaging expensive equipment and forcing costly production shutdowns.

1. Voltage swings put significant stress on energy-sensitive equipment, weakening spindle assemblies — with replacements costing $50k–$60k per unit
2. Unplanned voltage and frequency events forced shutdowns of vacuum pumps and anti-resistance chambers, triggering time-consuming  cool-down and restart cycles
3. Growing production demands were straining National Vision's sustainability commitments

1. Torus instantly corrects power quality issues helping prevent premature equipment replacements
2. Torus Spin provides ride-through power during brownouts, allowing vacuum pumps and specialty chambers to shut down correctly — preventing equipment damage and restart delays
3. Cleaner, more stable power extends equipment life, lowers replacement frequency, and reduces material waste — supporting National Vision's sustainability goals

National Vision operates four manufacturing plants nationwide, and South Salt Lake is the first to deploy Torus. The system is modular and scalable,  built to grow with production demands at this facility and to serve as a model for the others.
