Combustion retrofit for engines that have to keep running

We work on the engines a site cannot easily replace — standby plant, working fleets, marine auxiliaries, farm and light-industrial sets. We survey the engine, fit within a defined envelope, and measure the result on your fuel and your load.

We do not quote a figure before we have seen your engine. We measure your engine before and after fitting, under a protocol agreed with you, on your fuel and your load — and we give you those measurements.

Where we work

Before you ask us in

  • How the retrofit works — the engineering and the before-and-after test protocol, described plainly.
  • The engine envelope — what a retrofit is suitable for across sectors, and what is out of envelope.
  • The proof locker — the documents and measurements we can share, made available on request.
