Power-free ignition for remote, off-grid, and backup duty
CRA’s Piezoelectric Ignition Systems provide a portable, power-independent ignition source for flare pilots, burners, and auxiliary combustion equipment. Using mechanical energy to generate a high-voltage spark, these systems deliver instant, safe ignition without the need for external power or complex wiring. Built with robust, weather-resistant housings, our piezo-electric systems are ideal for remote, off-grid, or backup ignition duties—where reliability and simplicity are essential.

What is a Piezoelectric Ignition System?
A piezoelectric ignition system generates a high-voltage spark from mechanical energy alone, providing a portable, power-independent ignition source for flare pilots, burners, and auxiliary combustion equipment in locations without reliable electrical supply.
How it works
Mechanical force applied to a piezoelectric crystal assembly generates a high-voltage pulse that discharges across the electrode gap as an ignition spark.
The operator applies mechanical force through a manual lever or button, triggering the ignition cycle.
The force compresses the piezoelectric crystal assembly, generating a high-voltage electrical pulse.
The pulse discharges across the electrode gap as an ignition spark.
Sealed construction protects the crystal assembly and housing from moisture, dust, and corrosive exposure, keeping the unit ready to fire after long periods without use.

Frequently Asked Questions
What is a piezoelectric ignition system?
A piezoelectric ignition system generates a high-voltage spark from mechanical energy rather than an external power source, making it a fully power-independent way to light a flare pilot, burner, or auxiliary combustion device. CRA's units are built into rugged, weather-resistant housings for field use rather than a bench-grade component.
When is piezoelectric ignition the right choice over an electric ignition system?
Piezoelectric ignition is typically specified for remote, off-grid, or backup duty where running power to an ignition point isn't practical, or where a simple, maintenance-free manual ignition source is preferred over an automated electric system like HEI or HVI. It trades automated, continuous operation for power independence and mechanical simplicity.
How reliable is piezoelectric ignition in harsh or hazardous environments?
CRA's piezoelectric systems use corrosion-resistant construction to withstand harsh environmental exposure, and the ergonomic design supports repeatable ignition without operator fatigue across many manual actuations. Because there's no electronics to foul or batteries to fail, reliability comes from mechanical simplicity rather than diagnostics.
What ignition points is piezoelectric ignition compatible with?
CRA's piezoelectric systems are compatible with a wide range of pilot tips, burners, and flare systems, including elevated and ground flares, process burner start-up, and integration with a burner management system where semi-automated sequencing is still required. Compact, portable construction also supports quick deployment for maintenance or emergency ignition needs.
What industries use piezoelectric ignition systems?
Common use cases include hazardous area and remote locations, manual and self-powered ignition applications, and maintenance-free ignition for intermittent duty across chemical and petrochemical, oil and gas, and paper and pulp facilities. CRA tailors each unit to the site's fuel composition and flare setup even though the ignition mechanism itself is mechanical rather than electric.
