About Us
N40 Engineering was founded to close the gap between engineering design and in the field reliability.
With nearly a decade of experience supporting mobile equipment in the mining and industrial sectors, we specialize in control system audits, drawing cleanup, and technical support that actually works where it counts—in the field.
Whether you're building new equipment, rebuilding legacy assets, or just tired of chasing electrical gremlins, N40 Engineering is here to make your systems field-ready.
Founder Rich Didier led electrical and controls engineering improvements for one of the largest bulk explosives fleets in North America. From incremental upgrades to ground-up designs, his systems are relied on daily in some of the toughest operating environments in the world.
He has supported feasibility studies for both greenfield and brownfield refining facilities and is known as the go-to problem solver when no one else can find the answer.
We bring a practical, hands-on approach to control systems engineering—focused on uptime, safety, and long-term maintainability.
Let’s Work Together
Whether you’re chasing recurring reliability issues, need a controls audit, or want to clean up documentation before your next build, I can help.
I offer straight answers, practical solutions, and fast turnaround for industrial teams who need their equipment to work the first time.
