A/S Danish Engineering & Marine Power (DEMP) uses different types of starters on gen sets.

Emergency gen sets uses normally electric starters as these sets have their own starting battery package (24 VDC) (DEMP has also Battery chargers for marine use and Class approval) but some Class companies have requirements as to second means of starting device. For that purpose, have we hydraulic or spring starter systems in our product range. 

Auxiliary gen sets can use different types of starter systems depending on size of gen set and ship design (engine layout).

Short description of the different systems:

Electric starters:

Is normally use on smaller engines and this require battery package (24 ADC) and a battery charger installation.

MAN normally uses Bosch starters but Prestolite electric starters can also be used as alternative as these are cheaper. Both Bosch & Prestolite fit many engine brands and we are able to supply to other than MAN high speed engines upon request.

Air starters:

We have used Gali air starters for many years and can recommend this based on our knowhow. Gali starters is also used on many medium speed engines.

Spring starters:

This type of starter is used on some DEMP gen sets as second means of starting. In some cases, is the spring starter not installed on the engine but is used as replacement of the original electric starter if this is not working or if no 24 VDC is not available.

We have used/uses Startwell but other brands are also available as this type of starter is very similar due to the simple design. The spring starter is very good to use due to the simple design and use on older engines but newer engines with electric engine control/surveillance equipment might require electric power supply for start when using a spring starter.

Hydraulic starters:

Several brands make hydraulic starter systems but based on our experience then we recommend Prestolite which is installed on several DEMP gen sets.  This type of starters can be installed on the engine as back up starting and can be seen on many emergency gen sets in case of breakdown of the electric starter or if the 24 VDC supply is missing. However, this system is not available for all engine sizes. 

Starters used on DEMP plants and for MAN high speed engines are stocked items.
