Custom Vacuum and Compression Solutions for Complex Processes

NASH engineered solutions are designed for industrial processes where a standard pump, compressor, or packaged unit is not enough. These systems bring together vacuum pumps, liquid ring compressors, dry pumps, steam and air ejectors, hybrid configurations, separators, heat exchangers, controls, instrumentation, and auxiliary equipment into complete process-focused packages. 

From complex gas-handling applications to strict environmental, safety, and performance requirements, NASH engineered systems help customers address process challenges involving wet, dirty, corrosive, toxic, flammable, explosive, or otherwise difficult gases. 

Use this page as the main hub for engineered-to-order systems, pre-engineered and modular packages, vacuum systems, compression systems, hybrid systems, and application-specific engineered solutions. 

Types of Engineered Solutions

NASH engineered solutions can be configured around different vacuum and compression technologies depending on process requirements, gas composition, performance targets, and site conditions.

Engineered-to-Order Systems

When every process parameter matters, Nash delivers engineered-to-order systems designed from customer process data. These projects can account for gas composition, flows, pressures, temperatures, utilities, materials, standards, safety requirements, emissions goals, and site constraints. 

Engineered-to-order systems are especially valuable when the process includes challenging gases, tight performance targets, hazardous-area requirements, or a need to integrate multiple technologies into one complete package. 

  • Custom liquid ring vacuum and compressor systems for chemical, petroleum, power, paper, mining, food, and wastewater treatment applications
  • Application-specific systems for flare gas recovery, vapor recovery, VCM/VC processing, toxic or corrosive gas handling, hydrogen, and carbon capture
  • Integrated design scope including process review, equipment selection, controls, fabrication, assembly, testing, documentation, and lifecycle support

Pre-Engineered & Modular Packages

For common applications, Nash offers pre-engineered and modular systems that can simplify specifications while maintaining flexibility for process requirements. These packages are useful when customers need dependable performance with a more standardized system approach. 

Examples can include liquid ring vacuum packages, pre-engineered vacuum skids, modular dry vacuum systems, oil-sealed packages, and pre-separator units for process and utility applications. 

  • Condenser exhauster systems for power applications
  • Paper machine vacuum packages
  • General process vacuum systems
  • Modular dry vacuum systems
  • Oil-sealed and liquid ring vacuum units
