The Grupel Heavy Range is intended for projects where electrical capacity, integration and operational resilience must be considered as part of a complete engineered system. Configurable components and container formats allow each generator to be adapted to the site rather than forcing complex power requirements into a standard specification.
The Heavy Range extends from 800 to 3,150kVA, providing the capacity required by major industrial processes and critical infrastructure. These outputs can support substantial combined loads, including heavy machinery, cooling systems, pumps, production lines and extensive building services. Detailed load analysis is essential to account for equipment starting currents, operating sequences and the resilience required across the complete installation.
Grupel Heavy generators can be housed within purpose-designed containers that combine the generating equipment with the systems needed for a large permanent installation. Standard formats include 20-foot and 40-foot containers, alongside other enclosure configurations selected according to the generator and project. Containerisation can simplify site positioning while providing protected space for ventilation, acoustic treatment, controls and supporting equipment.
The range can be configured to supply low or medium-voltage electricity according to the wider distribution system. This makes Grupel heavy diesel generators suitable for facilities where power must be integrated with high-capacity switchgear, transformers or private electrical networks. Voltage, protection and connection requirements must be engineered specifically around the site and the equipment being supplied.
Heavy Range systems can provide a primary electricity source or protect critical operations when the mains supply fails. Continuous-power configurations are relevant to remote sites, power-generation projects and facilities with limited grid capacity, while emergency systems help maintain essential services during an outage. The selected engine, fuel system and control strategy should reflect the expected operating hours and changing load conditions.
Different engine and alternator combinations are available across the wider range, including options from Grupel, Perkins, Baudouin, Leroy-Somer and Stamford. Control systems can also be configured for automatic operation, remote supervision or synchronisation where multiple generators must operate together. This flexibility supports more complex installations requiring redundancy, load sharing or integration with existing power infrastructure.
