Efficient and Reliable Hybrid Vacuum Systems

Nash’s™ Steam Ejector Hybrid Vacuum System combines the reliability of liquid ring vacuum pumps with the high-vacuum performance of steam ejectors. This hybrid system achieves deeper vacuum levels while reducing greenhouse gas emissions and operating costs. Ideal for chemical processing, refining, power generation, and pharmaceutical applications, these systems are designed to maximize efficiency while ensuring long-term operational stability.

• Vacuum Range: Less than 1 mmHgA (1.3 mbar abs.)
• Suction Capacity: Custom-engineered to application requirements
• Applications: Vacuum distillation, reactor vacuum, evaporators, and more

NASH Air Ejector Hybrid Vacuum Systems integrate air ejectors with liquid ring vacuum pumps to create a cost-effective solution for low-flow deep vacuum applications where steam is unavailable or undesirable. These systems are ideal for applications such as deaeration, offshore platforms, and condenser exhausting.

• Vacuum Range: Down to 0.4 inHgA (13 mbar abs.)
• Advantages:
  • No steam required
  • Lower capital and operating costs
  • Efficient performance with minimal maintenance

When deeper vacuum levels are required beyond the capabilities of liquid ring vacuum pumps, Nash’s Booster Hybrid Vacuum Systems provide an optimized multistage solution. These systems combine vacuum boosters, liquid ring technology, and, in some cases, air ejectors for high-efficiency reactor vacuum and solvent dewaxing applications.

• Vacuum Range: Less than 1 mmHgA (1.3 mbar abs.)
• Suction Capacity: 850 to 33,980 m³/h (500 to 20,000 CFM)
• Ideal for:
  • Reactor vacuum (chemical industry)
  • Drying of solids (chemical, food & beverage industries)
  • Vacuum distillation (chemical, oil & gas industries)
