Nitrogen Starting Systems
IPU’s nitrogen starting systems provide powerful starting for large engines up to 320 litres. Our nitrogen systems utilise the standard Jetstream air starter to provide flexibility and capabilities not found with other starting technologies.
-
- We can design a custom nitrogen starting system to suit your requirements.
-
- To recharge simply replace the standard N2 cylinders.
Nitrogen is stored at pressures up to 350 bar. This pressure is reduced before entering the starter motor, supporting the long cranking cycle demanded by critical applications such as fire pumps.
IPU’s nitrogen starting systems are easy to deploy and maintain. They use retail gas cylinders resulting in a system that’s as compact as it is powerful. Once a starting cycle is complete the cylinders can easily be replaced by numerous suppliers.
Being an inert gas, nitrogen brings an added level of safety to starting in dangerous environments. It is the ideal solution for emergency backup to the primary starting system on applications such as fire pumps or generators in offshore and hazardous areas.

Nitrogen starting systems video
This video is an example of a nitrogen system in action.
The nitrogen starting systems are delivered fully assembled and ready to use. All components are mounted onto a freestanding skid, typically comprising of:
- Nitrogen bottles (provided by the end-user)
- 250 bar to 7 bar full flow pressure reduction valve
- High-pressure filter
- Hoses with nitrogen cylinder adaptors to connect to each cylinder.
- Manifold block incorporating:
- Pressure safety valve to protect the low-pressure items in case of reduction valve leakage or failure
- High and low-pressure gauges and stainless steel isolators
- Isolation valves for each nitrogen cylinder
- Low-pressure switch and stainless steel isolator (M20 conduit entry) set to 70 bar approximately
All items are mounted into a fully welded steel frame with two off lifting points. All fittings are stainless steel Swagelok twin ferrule type with stainless steel tubing. The paint finish is to standard offshore paint specification.
