📈 Growing Our Impact Through Decades of Mission Critical Reliability.

Since 1934, Simplex has helped customers prepare for the moments when power reliability matters most.

What began with a commitment to innovation in electrical engineering has grown into a legacy of in-house designing and manufacturing load banks, fuel supply systems, and related solutions for mission critical environments. Today, Simplex operates three production facilities that expand our capability to build the equipment customers rely on across industries where performance, quality, and dependability cannot be compromised.

Our growth is built on decades of experience, expanding capabilities, and a continued commitment to reliability and solutions.

Just as critical power systems depend on performance, Simplex depends on the people who make that performance possible.

Reliability matters most when lives depend on it. ❤️

At Simplex, we support mission critical environments every day, helping customers protect and maintain the systems they depend on when reliability matters most.

That commitment extends beyond our products. Through our recent blood drive with ImpactLife, Simplex employees came together to support hospitals and patients throughout our region who rely on a safe, reliable blood supply.

Thank you to every donor, volunteer, and team member who helped make the drive possible. We are proud to partner with ImpactLife and contribute to a mission that helps strengthen the communities we serve. 🩸
