Engineered control
for the shop floor.
Apex Control Systems designs, retrofits and services industrial machinery for the manufacturers, oilfields and fabricators — from concept to installation and support.
Three disciplines, one shop.
From custom builds and control retrofits to vendor-neutral repair and refurbishment — Apex covers the full life-cycle of industrial machinery.
Machine design & build
Bring us a concept; we'll deliver the machine. Apex builds completely custom industrial machinery — improving throughput, consistency and operator safety.
Read brief →Control retrofits
Good mechanical bones, dated electronics. We modernize legacy equipment with current PLCs, drives and HMIs — at a fraction of the cost of replacing it.
Read brief →Independent service
Vendor-neutral repair, refurbishment and preventative maintenance for brands across the industrial spectrum. We pick you up when your machine goes down.
Read brief →From the first walkthrough to commissioning sign-off.
Every project moves through the same four phases — disciplined enough to keep schedule, flexible enough to handle the surprises every shop floor will hand you.
