Gas Ejectors - Sampling Systems

Transvac Gas Ejectors can provide a simple, safe and inexpensive method for batch sampling corrosive liquids and solvents in the fine chemical and pharmaceutical industries.
There are two options available; a Direct Transfer System or an Indirect Transfer System.

Advantages

  • Reliable
  • Simple to operate
  • No moving parts
  • Materials to suit process
  • Small size
  • No ATEX considerations
Direct Transfer System

Direct Transfer System

In operation an Ejector uses motive gas (typically air or nitrogen) to create a vacuum to entrain process liquid from a reactor. The resulting mixture is discharged into a transfer pot where the two fluids separate. Gas leaves the transfer pot via a demister pad to atmosphere or to the plant pollution control system.
Once the volume of liquid reaches the preset level in the transfer pot the Ejector is switched off.

Indirect Transfer System

Indirect Transfer System

The Ejector uses motive gas to create a vacuum within the transfer pot to draw in process liquid. Gas from the Ejector can be discharged to atmosphere or to the plant pollution control system.
Once the volume of liquid reaches the preset level in the transfer pot the Ejector is switched off. The process liquid sample is simply drained by gravity from the transfer pot and any excess liquid returned to the reactor.
