"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.
