Applications
Where a retrofit fits, across the sectors we work in — the fuels, the power band, the duty cycle, and what is out of envelope. If your engine is near a boundary, that is exactly what a survey is for. We size to the survey, not to this table.
Standby and prime power plant
- Fuels
- Diesel and dual-fuel compression-ignition sets.
- Power band
- Roughly 20 kVA to 2 MVA single sets; larger by survey.
- Duty cycle
- Standby, peak-lopping, and continuous prime power.
- Out of envelope
- Not gas-turbine sets, not spark-ignition gas engines, and not sets whose exhaust cannot be safely interrupted for fitting.
Fleet auxiliary and transport refrigeration
- Fuels
- Diesel auxiliary and refrigeration engines.
- Power band
- Small auxiliary units up to roughly 50 kW.
- Duty cycle
- Intermittent and long-idle, typical of transport auxiliaries.
- Out of envelope
- Not the vehicle traction engine, not electric or hybrid auxiliaries, and not units under a manufacturer service contract that forbids modification.
Marine auxiliary
- Fuels
- Marine diesel auxiliary sets.
- Power band
- Auxiliary sets by survey; not main propulsion.
- Duty cycle
- Harbour duty, at-berth, and auxiliary running under way.
- Out of envelope
- Not main propulsion engines, not steam plant, and nothing that would compromise the vessel’s class or its exhaust safety case.
Agricultural
- Fuels
- Diesel generating and pump-drive engines.
- Power band
- Roughly 10 kVA to 500 kVA.
- Duty cycle
- Seasonal peaks, irrigation duty, and standby.
- Out of envelope
- Not the traction engines of tractors or harvesters, not spark-ignition engines, and not units that cannot be taken offline in season.
Light industrial
- Fuels
- Diesel site and small-plant engines.
- Power band
- Small sets up to roughly 100 kVA.
- Duty cycle
- Intermittent working-day duty.
- Out of envelope
- Not petrol or spark-ignition plant, not hand tools, and not engines that cannot be safely interrupted for fitting.
