Product catalog summary
Overview: The Gemini 2/3 Series 6-12KVA marine diesel generators are equipped with Mitsubishi diesel engines and synchron alternators. Key features include noise cocooning, 12V electric start, oil pressure and temperature supervision, battery trickle charging, heat exchanger cooling, speed fine adjustment, fuel lift pump, seawater pump, water-cooled exhaust manifold, anti-vibration mountings, and waste heat usage.
Standard Specification: The engine and alternator are close-coupled via bellhousing and resiliently mounted to minimize vibration. The system includes a failsafe mechanism for oil pressure and overheating protection. The sound enclosure is constructed using GRP and Balsa Wood with lead sheeting for acoustic performance. The design facilitates easy installation and service access.
Waste Energy Utilization: Waste heat from engine and alternator cooling can be used for onboard heating. A separate heating kit is available for installation. Cooling water can also be used to heat a calorifier for hot water supply.
Engine Details: The generators use a lightweight, high-speed water-cooled 4-stroke Mitsubishi diesel engine with interchangeable parts between 2 and 3 cylinder models. Features include a Bosch M-type injection pump, mechanical centrifugal governor, and forced oil lubrication system.
Alternator Details: The brushless alternator offers excellent motor starting capabilities and complies with various standards including BS 5000:3 and IEC 34-1. It supports dual voltage configurations and has an overload capacity of up to 300%.
Model Specifications: The document lists several models with varying KVA, KW, phase, voltage, dimensions, and weight. For example, the H2W6M1C model offers 6 KVA at 50 Hz with dimensions of 780x515x590 mm and a weight of 148 kg.
Technical Specifications: The Gemini 2 uses a Mitsubishi L2E engine with 11 HP at 3000 rpm, while the Gemini 3 uses a Mitsubishi L3E engine with 17 HP. Both models have a bore/stroke of 70/70 mm and operate at a DC voltage of 12V. Fuel consumption ranges from 3-6 liters per hour, and noise emissions are between 60-64 dBA at 7 meters.

Engine supports raised to achieve low vibration performance. All pipework and electrical wiring on set, Rating as per BS649 and DIN 6270, governing class A2. Failsafe system to provide protection against lack of oil pressure and overheating. Fan for hot air extraction from under the sound enclosure. Each set factory tested and sprayed in blue hammer, heat resistant paint. The sound enclosure is of substantial construction, combining the best use of GRP and Balsa Wood. Lead sheeting is laminated into the glass fibre structure to improve the acoustic performance. Noise reduction is considerable, bearing in mind the small dimensions and the low weight. The new cocooned set incorporates all relevant features to simplify installation on board. All services to and from the cocoon have external connections to ease service access and increase cost effectiveness. Waste Energy The radiated hot air created as a result of engine heat radiation and cooling of the alternator windings is expelled from the cover via an engine driven fan. This waste heat can be utilised for warm air heating on board. HFL offer a separate heating kit which allows for easy installation. Do not attempt your own modification without consulting HFL first since poisonous exhaust emission has to be considered. Cooling water from the engine heat exchanger can be utilised to heat a calorifier in order to provide hot water on board. http://www.hflgen.com/gemini6-12.html (1 of 2)
