A dedicated solution for every application

We can offer variable purities to suit your application, down to 10ppm remaining oxygen or 99.999% nitrogen. Each application requires a different purity, so by selecting a purity with the maximum oxygen level permissible we can optimise the cost and energy savings while adhering to the required specifications.

By using a higher specification, we can ensure a safety margin for your process. The quality of gas is monitored consistently via the on-line live oxygen analyser built into the system. We also offer additional oxygen analysers for storage tanks.

In addition to this, as a total quality control system, we have fitted a Pharma grade FDA approved BIO X sterile gas filter on the system which gives the gas a guarantee of protection far beyond what comes from a bottle of gas
