Common Specifications

Beta Marine has extensive experience from over twenty years of manufacturing marine bespoke generating sets for a broad spectrum of marine applications; From narrowboats, wide beams, dutch barges, sailing yachts, super yachts, to commercial fishing boats, trawlers, tugs, passenger ferries, cargo boats & fast patrol boats. These bespoke generating sets has resulted in the development of a standard base range of marine generating sets from 4kVA < 58kVA.

The BetaSet / Genset 4/2 is available as standard as:

• 2 Pole 230v 50Hz – 1 Phase operating @ 3,000 rpm or
• 2 Pole 120/240v 60Hz – 1 Phase operating @ 3,600 rpm.

All are available with either Heat Exchanger, Keel or Radiator Cooling.

We can supply most electrical voltages and frequencies between 120 – 240 volt single phase, additionally we can also build to bespoke individual specifications.

Emissions

• The BetaSet / BetaGen 4/2 is suitable for use on seagoing vessels with valid maritime or safety certificate, recreational craft and inland waterways vessels including the Rhine (CCNR) because the engine falls below 19kW.

• For EPA compliance, all sets must be specially quoted for.

Common Standard Specification

• Beta Marine water cooled ‘Kubota’ based diesel engine, naturally aspirated, mechanically governed as specified above for operation in accordance with ISO 3046* for marine diesel generating sets.

• Heat exchanger cooling complete with cupro-nickel tube bundle and phosphor bronze end caps, sacrificial anode, fresh water and sea water pumps. Water cooled exhaust manifold, water injection exhaust bend, sump drain pump, fuel, oil, and air filtration. CE approved fuel supply & return flexible connection hoses or

• Keel cooled header tank & water cooled exhaust manifold, fresh water pump, dry exhaust outlet including exhaust elbow & flexible stainless steel bellows, sump drain pump, fuel, oil, and air filtration. CE approved fuel supply & return flexible connection hoses.

• 12 volt electric start system with 45 Amp battery charging alternator and stop solenoid valve, 2 wire grounded system.

• A combined start/stop, alarm and protection module is supplied loose with 3 metres of connection cable. The module includes: engine start and stop push buttons, an hours run meter and indicators with shutdown on fault for either low lubricating oil pressure or high coolant temperature. On insulated system push buttons are replaced with a key switch and separate hour counter is supplied.

• The Mecc Alte marine rated “generator” operates at 0.8pf** and has a ventilated drip proof enclosure with IP 22 protection & single bearing construction. The generator is self-regulating, self-excited and is complete with terminal box and automatic voltage regulator. Suitable for operation in engine room temperatures of up to 45⁰C.

• 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 vessels seating.

• Paint: The generating set is painted Beta Red for heat exchanger or Dark Brunswick Green for Keel cooled engines, the acoustic enclosures are off-white.

• Each generating set is “full load” tested in accordance with our quality document QA023.

• Tri-wall packed on a wooden base.

• Warranty: 12 months from date of commissioning or 18 months from date of despatch – whichever comes first and subject to the Warranty Terms and Conditions, section 17 within our General Terms and Conditions of Sale.
  

*For operation in ambient temperature of 45⁰C the output will be de-rated by 8%. Please contact Beta Marine for further information.

**The BetaSet-BetaGen 4/2 single phase is a unity power factor kVA = kW generator.

BetaGen Additional Specification

Although our generating sets are quiet by comparison as standard, for customers or installations that demand especially quiet operation, Beta Marine have developed a highly insulated acoustic enclosure option. These enclosures reduce noise level down to a low 60 dB(A) when measured at seven metres under free field conditions at normal operating speed.

Manufactured from ‘zintec’ steel and finished in off white ‘powder coated’ paint to complement our engine colour, the panel frame is bolted together for rigidity & strength and is lined with high quality 38mm flame retardant acoustic foam material (including a 4mm polymeric barrier), held in place with high temperature silicon adhesive.

Quick release “service” panels facilitate easy, simple and unobstructed access to the engine, alternator and ancillaries. Acoustic attenuating ducts provide air flow in and out of enclosure assisted by a ventilation fan.

The design allows the engine and alternator unit to rest on flexible mountings within the enclosure and all necessary connections including speed control cable, battery +ve and -ve terminals, fuel inlet and return, cooling water inlet and return, calorifier feed and return (if specified), wet or dry exhaust outlet are all brought out of the enclosure – ready for a quick and easy installation.

Optional for all BetaSet/BetaGen models.

Double Walled Fuel Injection Pipes & Alarm

Double walled (sheathed) fuel injection pipes, in the event of an engine fuel injection inner pipe failure, fuel is leaked into the outer pipe which then feeds back to the fuel tank via a float chamber which activates an engine alarm.

Optional for 4 Pole BetaSet – BetaGen 21, 26 & 33.
