Vacuum Systems

Modular four (4) Stage Dry Vacuum System with (4) roots blowers, a twin screw dry vacuum pump and interstage and after condensers servicing process equipment operating at 0.1mbara, 0.4 mbara and 5 mbara.

Over the past 50 years Pfaudler has been supplying evaporators to various branches of industry. Nearly all these evaporators operate under vacuum conditions. Pfaudler frequently supplies peripheral equipment with our modular evaporation systems including custom designed packaged vacuum systems. These unique circumstances have allowed the engineers at Pfaudler to develop an expertise in vacuum system design for evaporation processes, especially dry vacuum systems.

We have worked closely with numerous vacuum equipment suppliers and provided unique and custom designed packaged vacuum systems. If you have an application which cannot use an off the shelf vacuum system, contact the engineers at Pfaudler. We have supplied packaged vacuum systems comprised of multiple steam jets, rotary vane pumps, rotary lobe pumps, liquid ring pumps, eductors, dry vacuum pumps, vacuum blowers, interstage coolers, interstage condensers and more. Our services range from designing a packaged vacuum system for you to building a modular automated system which can be easily integrated into your existing facility.

Features:

• Vacuum operation from 760 to 0.001 torr (1013.25 to .00133 mBarA)
• Interstage condensers and coolers to help limit capacity through temperature reduction and vapor to liquid phase changes
• Multiple stage designs
• Multiple vacuum connection points
• Fully instrumented systems to manually controlled systems

Modular five (5) Stage Vacuum System with (3) roots blowers in series an interstage condenser and 2-stage closed loop liquid ring pump utilizing a solvent as the motive fluid servicing four (4) evaporation stages operating at 0.07mbara, 0.6 mbara, 6 mbara and 40 mbara.

Questions We Answer on a Normal Basis:

• What's the process carry over from my partial condenser?
• What size piping should I use within my vacuum system?
• What is the allowed compression ratio between 2 or 3 vacuum blowers operating in series?
• How do I remove condensing vapors from a system operating under a vacuum?
• What's the best location for a bleed back or air bleed valve?
• What type of interlocks should I use to protect the equipment?
• What is the estimated air leakage into the system?
• How does vacuum affect the forces within a piping design?
• How do I build this system to accommodate capacity increases in the future?
• How can I use one vacuum system to supply different operating pressure to varying locations within the process.
• How do I shut the system down if the product degrades upon exposure to Oxygen?
• Is it better to control the vacuum pressure through a spill back or the varying the rotational speed of the equipment?
