BetaGen Marine Generating Sets

Single and 3 Phase Beta Marine – BetaGen ‘Super Silence’ Marine Generators with acoustic housings.

Our marine generating sets are manufactured with high quality marine grade acoustic housings that reduce the noise levels down to below 60dB(A). This is (at least) a further 10dB(A) reduction from our already quiet gensets – equivalent to about half the noise level as perceived by the human ear.

Our BetaGen Marine Generating sets have been carefully designed to have compact dimensions and low weight, with all service connections brought to the outside of the housing – ready for a quick and easy installation.

We also included in the design for ease of maintenance with quick release panels, and special acoustic reduction material with attenuated air-intake and exhaust connections.

Single and 3 Phase Marine standard BetaSet Generating Sets and BetaGen “Super Silence” with acoustic housings. Specifications as detailed in our current brochure.

BetaSet Specifications

Having a maximum rated output as detailed; designed, built and tested by Beta Marine Limited, each comprising:

  • Powered by a Beta Marine water cooled ‘Kubota’ marine specification heat exchanger cooled auxiliary diesel engine naturally aspirated and rated at either 1,500 rev/min (or 3,000 rev/min, 2-pole versions) for operation in accordance with ISO 3046.
  • Heat exchanger cooling complete with cupro-nickel tube bundle and phosphor bronze end caps and anode, with fresh and sea water pumps.
  • Water cooled exhaust manifolds and water injection exhaust bend.
  • 12 volt electric start system with battery charging alternator and stop solenoid valve, 2 wire grounded system (insulated return is standard on BetaSet/BetaGen 26, 33, 40 and 49).
  • Combined start/stop, alarm and protection module is supplied loose with 3 metres of connection cable. Module includes:- Starting and Stopping push buttons, an hours run meter, and indicators with shutdown on fault of low lubricating oil pressure and high coolant temperature.
  • Speed governor to control engine speed to the requirements of ISO 3046 for diesel generating set.
  • Beta Marine standard fuel oil, lubricating oil and combustion air filters. Engine mounted sump drain pump.
  • Mecc Alte alternator marine rated to ISO standard, brushless, self ventilated with IP 22 protection, single bearing construction. The generator is self regulating and self excited and is complete with terminal box and automatic voltage regulator, fully suitable for use in engine room environments of 45°C.
  • Engine and generator are close coupled together and mounted on substantial steel feet with marine failsafe anti-vibration mountings to isolate the set from the ships seating.
  • Paint: Beta Red for heat exchanger cooling or Dark Brunswick Green for keel cooling.
  • Each generating set is “full load” tested in accordance with our quality document QA023.
  • Warranty: 12 months from date of commissioning or 18 months from date of despatch – which ever comes first.
  • Keel/box cooling versions are available (see note b) and alternative specifications and requirements can be quoted on request.

BetaGen ‘Super Silence’ Specifications

The specification is basically the same as the BetaSet generating set but fitted with an acoustic enclosure: Our BetaGen marine generating sets are manufactured with high quality marine grade acoustic housings with zintec/steel, a 40mm sound insulated lining and removable panels for easy maintenance; the noise level will be less than 60dB(A) when measured at 7 metres under “free field” conditions. This is (at least) a further 10dB(A) reduction from our already quiet gensets – equivalent to about half the noise level as perceived by the human ear.

Please also refer to our sales brochure “Marine Generating Sets 3 to 50kVA” ref: 1760.
