20kVA to 20MVA
The scale of your operation or the hardware that needs a backup power source will determine the capacity of the generator you need.
We can supply and install generators from 20kVA for small to medium scale requirements right up to 20MVA for more industrial needs.
LV / MV sets and switchgear
LV or MV switchgear is used to interrupt currents to prevent damage or to power down to allow for maintenance or the replacement of components.
We can supply and install LV and MV generator sets and switchgear to give you control over your installation.
Diesel tank fabrication, supply, installation
Diesel storage goes hand-in-hand with on-site generation, and you'll want to confident in the integrity of your storage tank.
We're experienced in the design and fabrication of diesel tanks that meet technical and environmental regulations as well as ISO quality standards.
Our experienced engineers will build to spec and install at your site, giving you ultimate peace of mind.
Diesel pipework
Designing diesel pipework for generators presents its own challenges and demands careful consideration of criteria from fuel storage, pumping and piping to cooling, maintenance and system control.
Our capable engineers are tried and tested experts who will listen to your needs, design the right solution and ensure that it's both efficient and compliant with industry standards.
Synchronisation and G.99 export
As part of the installation of your generator by our team, we can carefully synchronise the settings to your existing main power supply. This will help to ensure that, in the event of the generator being needed, your infrastructure will receive little or no interruption to normal conditions.
If you're running a large-scale generator and intend to relay some or all of your generated power to the national grid, you'll need to adhere to G.99 (ex G.59) regulations. Talk to us about your plans and we'll help you to understand your obligations, configure your system and comply with the relevant regulations.
Large stock of new and used machines
We work on many engineering projects every year and have a wide range of both new and used generators available for sale or hire.
We sell fully guaranteed models from leading brands, while all of our used stock comes fully serviced.
Whether you buy new or reconditioned, we'll supply and install at your premises and offer you a maintenance service to keep your generator in optimum condition.
