  • Regulatory
  • Batching systems
  • Routing control
  • Equipment sequencing and interlocking
  • Particle size reduction
  • Agglomeration and pelleting
  • Cooling and drying
  • Fluidized bed controls
  • Coating systems
  • Kiln & Roaster control
  • Paper milling processes
  • Hydraulic systems
  • Electron-beam furnaces
  • Utility controls
  • Power generation controls
  • Mining /Ore processes
  • Liquid handling & control systems
  • Automated machine control
  • Safety-integrated control systems
  • Failsafe Systems
  • Redundancy



Unlike most engineering firms, PSE also has our own panel fabrication shop in our Sandy office.  This shop is equipped with all the facilities required to build any panels needed by our clients.  PSE is registered with Underwriters Laboratories (UL) as a UL508A industrial control panel builder (UL category NITW).  All control panels built by PSE comply with the UL508A standard to insure safety and quality.

Having the company that designed your control system also build and test the system insures that your control system performs as designed and manages your plant operations with maximum efficiency. PSE can perform Factory Acceptance Testing (FAT) at our facility.

PSE can work with all panel ratings from NEMA 4X to NEMA 1.  In any size and even create combinations of panels.

PSE also can provide specialty equipment such as a 480 volt 3 phase six axis motion control system.



*On June 1, 2016 after more than 30 years of life, Rockwell Automation announced the discontinuation of the Allen-Bradley PLC-5 control platform in June 2017 and will no longer be available for sale. Contact PSE to plan your migration to a new PLC platform today.
