Safety Isn't Optional—It’s Certified 🛡️

When choosing a partner for control panels, the UL 508A label is non-negotiable. It’s your guarantee that the panel meets rigorous safety and quality standards.
As a certified UL 508A shop, we build peace of mind into every enclosure.

The "No-Surprises" Installation 🏗️

Nothing stalls a project like a panel that doesn't work upon arrival. That’s why we perform rigorous Quality Control Testing and partner with our customers to support their Factory Acceptance Testing (FAT).
We check each panel at every stage so you can be confident it will commission cleanly, avoiding lost production time.

"It doesn't leave our floor until it's perfect."

That isn't just a slogan; it’s our standard operating procedure. Before any control panel is packed for shipping, it undergoes a rigorous series of checks. This includes thorough point-to-point testing and air pressure checks for pneumatic systems to ensure every connection is secure and every circuit functions exactly as intended.

Our goal is a "Clean Commissioning." We want your setup process to be so smooth that you forget we were even there. When you receive a build from Simplex.

A control panel is an investment, not just a line item in a budget.

When evaluating quotes for your next project, it’s easy to focus solely on the initial price. However, the "cheapest" panel often becomes the most expensive the moment it hits your floor.

1. Delayed commissioning due to wiring errors? That’s money lost.
2. Component failure due to poor thermal design? That’s downtime.
3. Difficult maintenance because of lack of labeling? That’s increased labor costs.

At Simplex, we focus on the Total Cost of Ownership. Our builds pay for themselves through sheer reliability and the peace of mind that comes from knowing it will work perfectly the moment you power it up.

Why wait weeks for custom enclosures when you can have them in days?

Traditional manual drilling, cutting of enclosures is not only slow and it’s prone to human error. That’s why we’ve invested in the Steinhauer ModCenter. This automated system allows us to perform precision cutouts and modifications on almost any enclosure with surgical accuracy.

The result?

1. Drastically reduced lead times.
2. Perfect alignment for every component.
3. Consistent quality across every single unit in a production run.

We combine this high-speed automation with our team's deep technical knowledge to deliver a superior product faster than the industry standard.
