Local area vacuum networks for laboratories

VACUU·LAN® vacuum networks make it possible to supply several different applications with one vacuum pump; this is a money- and space-saving solution when a lot of users are working with vacuum in one laboratory. This also avoids the numerous drawbacks of a central ("house") vacuum supply. These very versatile modules for single workplaces can be subsequently upgraded. All of the components are available for new laboratory furnishings or for installation in existing or renovated laboratories. All of the subassemblies are very resistant to chemicals and have built-in check valves to ensure that adjacent applications do not contaminate or interfere with one another.

Just three steps to the appropriate local vacuum network

Step 1: What kind of application?

Select your applications from our vacuum application guide.
Define the needed working vacuum.

Applications that are not well suited to laboratory vacuum networks include those with:

  • very large volumes or a constantly high level of vapor production (such as a vacuum drying oven or dessicator with very "wet" samples)
  • vacuum needs of < 2 mbar

Step 2: What kind of vacuum port?

Which of the vacuum connections listed meet your requirements?

  • Shut off (ball valve)
  • Manual flow control (for example, very small applications should have flow-control regulation)
  • Electronic vacuum regulation with an in-line solenoid valve and vacuum controller, for applications where automated vacuum control is important for process or productivity reasons
  • Mounting bases for an existing laboratory or one in planning?

Step 3: Which vacuum pump or which pumping unit?

Condensate protection should always be used on the suction side and an emission condenser should be used on the exhaust side. An electrically-cooled condenser ("PeltronicTM") eliminates need for cooling water connections. Also check:

  • the working vacuum needed in the network: Select the larger pump in borderline cases
  • the pump's required volume flow rate: This depends on the number of connections that will be used simultaneously
  • pump and cooling water management: The vacuum and cooling water are regulated as needed. Automatic on-off regulation of pumps and cooling water reduce power and water consumption, and extend service intervals
  • for unsupervised operation: Liquid level sensor on emission condenser catchpot recommendable (with vacuum controller only)
