Marelli generators are designed to offer not only the best possible reliability, but also the best technical solution.

Cooling

Marelli Marine generators cooling methods include:

> TEWAC-Totally Enclosed Water to Air Cooled           Type：A series of MJHRM/MJRM

> ODP-Open Drip Proof                                              Type：A series of MJHM/MJBM

> TEAAC-Totally Enclosed Air to Air Cooled                 Type：A series of MJVM

Approvals
The generators are design and built in accordance with marine register rules specifications and comply with: ABS, BV, CCS, DNV, GL, KR, LR, NK, RINA, RS.

Safety
> Leackage detector for water cooled generators (IC81W/IC86W solutions)
> CT`s for differential protection (above 1500kVA)
> Interface towards external safety systems like B.O.S.S. for rapid action in case of failure situations
> PT 100 sensors for temperature monitoring of stator winding and bearings.
> Anti-condensation heaters are available for all frame sizes.

Totally customisable
> Prepared for vibration sensors
> Anti friction or sleeve bearings are available. For sleeve bearings, forced lubrication and jacking system are available for special or low speed applications 
> Hybrid propulsion possibility using special exciter system for nominal torque from low speed
> Digital excitation/AVR systems acc to customer requests
> Degree of protection from IP23 to IP55
> 50Hz/60Hz or variable speed solution for DC grid solutions
> Speeds/Poles not mentioned in the brochure are available on request. 
> Nominal voltage from 380 to 6.600 Volts
> All generators are customizable to for optimal performance for each specific project
