Our solutions

We offer a range of solutions to suit your needs:

Leak detection surveys

Our highly experienced SF₆ engineers can carry out leak detection surveys on your site using specialist thermal imaging technology, either to locate a specific leak or to survey entire SF₆ filled installations; such as Gas Insulated Switchgear substations. This allows us to make strong recommendations as to where closer monitoring and repairs may be required.

Gas leak repairs

We will work with you to develop gas leak repair solutions that will be tailored to your site specifications to reduce financial and environmental cost. We use bespoke reporting tailored to your requirements. These reports identify the location of your leaks and can form the basis of a rectification plan.

Top-ups

Our experts can attend your site with equipment to empty or top up your SF₆ assets. We can complete this service both pre and post maintenance. Alternatively, we can top up leaking assets for them to continue performing until a repair can be carried out.

Gas handling

Our team will use specialist gas handling equipment to remove and temporarily store SF₆, allowing us to perform the necessary maintenance to restore your asset.
