Standard Specification Engine and alternator close-coupled via bellhousing and resiliently mounted. Engine supports raised to achieve a low vibration performance. All pipework and electrical wiring on set. Rasting as per BS649 and DIN 6270, governing class 2. Failsafe system providing protection against lack of oil pressure and overheating. Fan for hot air extraction from beneath the sound enclosure. Each set factory tested and sprayed in heat resistant paint. The sound enclosure is of substantial construction, combining the best use of GRP and BALSA WOOD. Lead strips are 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 set incorporates all relevant features to simplify installation on board. Engine Low weight, low profile, slow-speed watercooled 4-stroke ISUZU with indirect injection. Cylinder heads and blocks are light-weight but rigid with high durability. Low noise, smooth running characteristics with individual injection pump and mechanical centrifugal type governor. Forced oil lubrication system. Marinisation by HFL using dual circuit cooling via heat exchanger and watercooled exhaust manifold with water injected elbow. Belt-driven seawater pump with easily accessible belt tension adjustment. Alternator Brushless, lightweight alternator. Good current-compounding characteristic which offers excellent motor starting without overloading the engine. Power factor 0.8. Temporary overload capacity of up to 300% maximum i.e. 2 to 3 times full load current. Radio suppression to meet VDE 0875 grade N and BS 800 as standard. All machines to comply to BS 5000:3, BS 4999, IEC 34-1 and VDE 0530. Voltage 115-230 dual 1-phase: 220/380 3-phase. All machines are available in 60Hz or 3-phase configuration, please contact HFL for further details. |
