nitrogen gas generator

2.6  site location and installation

When selecting an installation site for the generator , ensure the following conditions are met:
• 

The site should be located indoors on a flat surface protected from weather and other harmful conditions.

•  The ambient temperature must not drop below 5°C (41°F) or exceed  50°C (122°F).
•  The installation site should be level and able to support the weight of the product.
• 

Ensure sufficient space around the product, we recommend at least 1m around the generator to allow access for 

operation and maintenance.

• 

Take into account the noise generated when in use when considering the final location.

Due to the nature of operation there is a possibility of oxygen enrichment surrounding the generator. Ensure the 
area surrounding the generator is adequately ventilated.

Once the generator has been located into position, install ball valves and the pipework ready for connection to the buffer 

vessel and compressed air supply. The diameter of the pipes must be sufficient to allow unrestricted inlet air supply to the 

generator and nitrogen supply to the applications. Ensure that all piping materials are suitable for the application, clean and 
debris free. All outlet piping must be solid and non-porous to minimize the ingress of oxygen. When routing the pipes ensure 
that they are adequately supported to prevent unnecessary strain which can lead to damage and leaks in the system. The 

nitrogen buffer vessel must be rated to at least the maximum operating pressure of the system and must be fitted with a 

suitable drain valve, pressure gauge and pressure relief valve.
