Diesel Marine Propulsion Engines & Generating Sets

Project Description

Inland Generating Sets

Beta Marine has gained considerable experience over many years manufacturing marine generating sets for Narrowboats, Wide Beam & Dutch Barges arranged for keel cooling or heat exchanger cooling. These small marine generating sets are based on Kubota diesel engines from 3.75kVA up to 50kVA; available as a standard generating set or acoustically housed.

  • A Quality robust design – manufactured for reliable and dependable long life operation.
  • Low noise levels as standard – acoustic housings an option!
  • Keel or Heat Exchanger cooling.
  • Lloyds Register “Design Appraisal” from 9kW.
  • ‘Recreational Craft Directive 94/25/EC as amended by 2003/44/EC’ emission compliant.
  • Generating Set Warranty is 12 months from commissioning in accordance with our standard terms.

Our BetaGen range of generating sets have high quality Acoustic housings that are 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 can supply most electrical voltages from 230 volt single phase; 3 Phase 400 volt etc. 50Hz or 60Hz. We will be pleased to discuss your generating sets requirements.

Standard Specifications

  • Heat exchanger cooled, the Beta 43, 50, 60 & 75 are naturally aspirated, whilst the Beta 70, 85, 90, 105 & 115 are turbocharged.
  • 4 cylinders with high inertia flywheel for smooth running at low rpm.
  • Heater plugs for cold starting below 5°C, fuel filter, mechanical fuel lift pump, mechanical fuel injection pump and mechanical engine governing ensures steadfast performance regardless of ambient conditions.
  • Quiet gear driven camshaft for maximum engine reliability and reduced servicing, as no timing chains or toothed belts have to be replaced.
  • Three vortex combustion with indirect injection for quiet running, low emissions and excellent fuel consumption – Beta 43, 50, 60 & 75.
  • ICVS combustion with direct injection for quiet running, low emissions and excellent fuel consumption – Beta 70, 85, 90, 105 & 115.
  • Mechanical & hydraulic, in-line, down angle or V drive gearbox options. Output rotation is clockwise in ahead, viewed from the gearbox end.
  • Subject to criteria, Kubota based engines accommodate installation angles up to 15° maximum when static and 25° when heeling.
  • 70 amp battery charging alternator giving full power at cruising speed with 12 volt electric starting as standard. Optional or additional alternators and polyvee belt/pulley drive transmission are available.
  • Complete with “ABV” Control Panel & 3m of interconnection cable, “Morse” type engine speed and gearbox control brackets & end fittings. Heavy duty feet and flexible mountings.
  • Optional special feet service, to ease planning and installation Beta Marine offer 3D computer aided modeling for the design & the manufacture of bespoke feet to allow direct installation on to your vessels existing engine bearers.
  • Subject to installation criteria & registration, Kubota based engine`s used for recreational use benefit from a 5 year ‘self-service’ engine warranty.
  • Red paint.

Gearbox Options

Beta Marine offer the following gearbox options and reduction ratios. We have selected suitable gearboxes to match the torque loading of each engine, and this will be correct for the majority of yachtsmen and canalboat owners. Some customers, such as commercial fishermen, may require a heavy duty gearbox and/or different reduction ratios to suit their heavy duty requirements. We can also mount your old/existing gearbox on a new Beta engine, if you wish to send it to us. Find out more…
