Customization at its Best

Our specialist teams of project engineers have designed and built tailor-made solutions to meet our customers’ specific vacuum and pressure needs for many decades. We are committed to extensive and continuous Research and Development to enable us to engineer tailored solutions for a wide array of applications.

Designing and building engineered solutions requires a high degree of expertise. Elmo Rietschle is such an experienced and competent partner; we will be pleased to help you with assembly and installation, initial operation guidance and consultancy in all vacuum and pressure matters.

Applications

  • Blast air and vacuum supply for applications in printing and paper industries
  • Lifting, holding, handling and clamping
  • Conveying
  • Distillation
  • Evacuation of industrial furnaces
  • Packaging
  • Impregnation
  • Degassing of sintered material
  • Cooling


Prompted by needs within the semiconductor industry, dry running vacuum pumps began being developed in the 90s. Today, dry running screw vacuum pumps are designed and manufactured for use in various vacuum systems and applications. A process requiring a complete vacuum package can be selected from a wide range of standard vacuum packages previously created and constructed for specific applications.

 

Thin film evaporation

Customized Systems

Vacuum system for manufacturing tert-Butyl acrylate (TBA)
German Client

Requirement: 

Exhaust vapor suction with recirculation into reactor
Ex requirement for pump (internal): Ex II 3G c IIB T3
Ex requirement for pump (external) Ex II 3G c IIB T3

Operating conditions:

  • Suction pressure approx. 40 mbar (abs)
  • Volume flow rate up to 3000 m3/h

Solution:

  • Dry running vacuum pump stand with three screw pumps, type VSB, each 500 m3/h, running parallel and with upstream roots pump

Advantages:

  • Economic due to recirculation and fewer emissions
  • Energy-savings due to the use of frequency converter
  • Broad vacuum range (from 1013 to 1 mbar abs)
  • No water contamination
