jbj Techniques has introduced an expanded range of GALI engine starting and protection systems, highlighting a systems-led approach to improving reliability, safety and operational control in large engine applications.

Detailed in a newly released technical catalogue, the range combines air and hydraulic starters, flywheel turning mechanisms, air shut-off valves and ATEX compliant alternators into a coordinated solution designed for use across sectors including marine, power generation, oil and gas, and heavy industry.

Rather than focusing solely on engine output, the approach reflects a broader engineering challenge: ensuring consistent performance and protection throughout the full operating cycle, from pre-start checks through to emergency shutdown and onboard power generation.

At the core of the range are high-performance air and hydraulic starters, engineered to deliver high torque and rapid acceleration to ignition speed. Operating directly at pressures of 30 to 40 bar, the systems eliminate the need for pressure-reducing valves, simplifying installation while maintaining reliability in harsh operating environments characterised by vibration, temperature variation and high humidity.

The starter portfolio supports engines exceeding 12,000 kW and is designed to accommodate both compact installations and large-scale industrial systems, with an emphasis on durability and reduced maintenance requirements.

Pre-start integrity is addressed through flywheel turning mechanisms, which allow controlled low-speed rotation of the crankshaft for inspection and alignment. This enables early identification of issues such as hydraulic lock or mechanical obstruction, helping to prevent damage to critical components including pistons, connecting rods and bearings. By enabling verification before ignition, the systems support a shift from reactive maintenance to condition-based and preventative strategies.

Safety-critical operation is further supported by air shut-off valves (ASOV), designed to mitigate the risk of engine runaway in hazardous environments. By rapidly isolating the engine air intake, the valves provide an effective shutdown method where conventional controls may be insufficient. Designed to operate across temperatures from -20°C to 230°C, they are suited to demanding industrial and process environments where safety and compliance are key considerations.

The latest addition to the range includes ATEX compliant flameproof alternators, designed for use in hazardous areas where ignition risk must be carefully managed. Engineered for belt-driven operation, the compact units are particularly suited to industrial vehicles and mobile equipment, where space constraints and installation flexibility are critical.

The alternators deliver continuous output of up to 595W at 14V and 420W at 28V, with peak performance reaching 840W (14V) and 630W (28V) for up to ten minutes. This enables rapid initial battery charging, supporting reliable system start-up and operation in demanding environments.

According to jbj Techniques, the integration of starting, inspection, shutdown and power generation technologies reflects a growing emphasis on systems engineering within high-value applications. By ensuring compatibility and coordinated performance between components, the approach aims to improve overall system resilience and reduce operational risk.

In sectors where unplanned downtime carries significant cost and safety implications, such integration supports not only performance, but also predictability and control throughout the lifecycle of the equipment.

The GALI product range is available in the UK through jbj Techniques, with full technical specifications provided in the latest catalogue.
