HOERBIGER provides high-performance solutions for ignition systems and accessories, engine controls, and digital instrument components for industrial engines, while complying with all applicable environmental regulations.

Digital ignition systems for natural gas and dual-fuel engines

VariSpark is a digital ignition system for gas-powered engines developed by HOERBIGER.

The system is available in XL size for large-bore, slow-speed gas engines, as well as XM / CPU95-VS and XS / CD200-VS, which are suited for smaller engines.

The HOERBIGER DriveCOM system is a modular, scalable, and integrated control system for internal combustion engines.
The CPU-95EVS (enhanced VariSpark) is a digital ignition system for industrial engines
The range of Altronic’s ignition systems, EZRail modular wiring rails, ignition coils, secondary leads, and spark plugs are widely respected by industrial engine operators.
HOERBIGER explosion relief valves offer reliable protection for staff and equipment against the effects of oil mist and gas explosions on engines and compressors.
HOERBIGER supplies plate check valves, which are time-tested for reliability, low pressure drop, and non-slam operation, even in pulsating flows.

It can produce a maximum spark of 50,000V, and adjusts the voltage level to meet the respective gas mixture and application of the engine.

VariSpark assures reliable combustion by eliminating misfires. Additional benefits include high-efficiency, and reduced nitrogen oxide emissions of the gas engine.

Control systems for internal combustion engines (ICE)

The HOERBIGER DriveCOM system is a modular, scalable, and integrated control solution for ICEs used in stationary, off-road, and marine applications.

The device monitors all critical engine parameters to maintain efficient and reliable operation.

Electronic modules in the system can be combined to create customised units suited to a variety of applications. This open system software allows easy integration into the customer’s control architecture.

Industrial explosion protection and safety technology

The HOERBIGER Explosion relief valve provides efficient protection from the consequences of gas explosions in dual-fuel and gas engines.

They protect intake and exhaust pipes of large engines, commonly used in power generation, and the shipping industry.

The opening pressures, design and material selection of the explosion relief valves can be matched individually to the particular application.

Components for explosion protection are virtually maintenance-free, ensure flameless explosion pressure venting, and minimise the danger of fires and secondary explosions by immediately sealing again.
