  • NOMAD 65 Neo

    Nomad 65 Neo is the new all-terrain broadband vibrator. Evolution of the popular Nomad 65 with enhanced mechanical and hydraulic components and shaker redesign, it is capable of delivering stronger low frequency content with full drive achieved from 5.4Hz.

    This enhanced performance is made possible using the latest innovations in shaker and hydraulic circuitry design.
    Another newly developed feature is the IPM (Intelligent Power Management) system.

  • AHV IV362

    In September 1985, the Detroit Diesel Engine Company used the electronically controlled unitary fuel injection control system for the first time on its high-speed diesel engines. The system was called DDECI. In September 1987, the more advanced DDECII system was introduced and later DDECIII, DDECIV, DDECV systems.

    DDECIII, DDECIV and DDECV systems are a unique set of diesel engine electronic control devices, which have the ability to collect more information and strictly control diesel engine emissions. The power supply voltage of DDECII system is 12V. The power supply voltage of DDECIII, DDECIV and DDECV systems can be 12V or 24V. The normal working voltage of ECM is between 11-32V.
