Gas Tight Version

WARNINGwarningwarningwarning

warningwarning

Media potentially dangerous.

Risk of poisoning!

Risk of infection!

  1. Wear appropriate personal protective equipment in case of high concentration of the medium in the ambient atmosphere of the machine.

The gas tight version is a design option for applications where the process gas remains in the machine and does not escape to the environment.

It is a very important feature for applications where gases potentially dangerous to human health are not allowed and the concentration of the process gas must not exceed the admissible values of the ambient atmosphere of the machine.

This machine is specifically equipped with:

  1. pressure relief lines
  2. collecting lines
  3. shaft seal rings

Requirements for a proper functioning:

Description

Ambient pressure

The gas tight machine requires an ambient pressure at the gas discharge during the whole operation range of +/- 200 hPa (mbar), unless otherwise specified on the nameplate.

Leakage rate

The machine is not absolutely gas tight.
The leakage rate of the machine described in this manual is of 0.1 hPa l/s (mbar l/s) at a suction pressure of 250 mbar. It can considerably increase up to prohibited pressure values at the gas inlet/outlet due to used shaft seal rings or clogged pressure relief lines.

Ambient environment

Closed air cooling systems are not suitable and therefore prohibited.

  1. Make sure that the machine is sufficiently vented (see Installation Conditions).
