Process Equipment Modules

Modular Process Equipment can reduce plant outage windows, improve construction schedules, increase safety and reduce construction costs by reducing on-site congestion during critical plant production outages.

From small packaged pump skids to large process units, fabricated modular packages are often a cost-efficient alternative to on-site stick-built construction.

PTI’s engineering, design, and fabrication team is accustomed to constructing packaged equipment modules or skids for a broad range of customers and industries.

The packaged equipment approach offers an opportunity to shift on-site construction labor to our shop, where your skid can be fabricated, prewired, inspected, and tested before leaving for your facility.

our work

blower and vaporization skid

Blower and Vaporization Skid

This small process skid package included a pair of centrifugal blowers, motor starter panels, and instrument junction boxes for one of our manufacturing clients.   This system included purged and pressurized motor starter panels suitable for Class 1, Div 2 hazardous area locations.  

plug and play pump skids

Plug and Play Pump Skids

These pump skid packages contain the pumps, isolation valves, check valves, and interconnecting piping headers designed to stack together to accommodate changes in your flow demands.   We designed the unitized structural steel bases to set in place from a tilt deck utility trailer to accommodate sites with limited equipment availability.  

Our System integration group also provided these rack mount VFDs and small PLC control panels, completing the package for this production pad.
