Igniters (spark plugs) will "skip" as they approach the end of their useful life. Chentronics offers a system that observes the release of energy, and indicates if the average is below minimum. In addition, this option integrates "Zero Voltage Contact" ON/OFF control and observes the quality of the input power source (allowing the operator to distinguish between the two most likely reasons for an ignition fault.) The diagnostic circuit is fail-safe; any fault of the diagnostic circuit will not affect normal operation.

The most common problems with burner operation are associated with starting. We have used decades of experience
to develop features that minimize the chance that the spark is ever an issue. Consider the following features
and the benefits:
SAFETY The flexible harness connecting the exciter to the rod is covered with PVC insulation
AND the discharge path is isolated from frame. This approach minimizes
current flow through the input ground reference. Arcing to frame is virtually
eliminated. In addition, the output of each section is female: this minimizes the
chance of personnel getting shocked, should the exciter be operated open circuit.
MODULAR ASSEMBLYEach section is easily replaced: the harness has large military type twist connectors that can be removed with a gloved hand, and the igniter tip threads are coated
with a high temperature graphite compound at the factory. The internal sub-assembly
is mounted as a single block that is easily removed.
NO YELLOW METALS H2S is commonly called "Sour Gas". It is often a byproduct of many industrial
processes. H2S gas accelerates erosion of yellow metals: in particular copper,
bronze and brass. This system does not use yellow metals; the exposed metal of
the rod and igniter are high-grade stainless steel and inconel.
ADVANCED ELECTRONICS The exciter accepts a wide input voltage range: 85-265 VRMS (50-60 Hz). The discharge circuit does not use a gas discharge tube.
These improvements yield these benefits:
- Increased spark size and intensity, for improved ignition
- Reduced power draw and physical volume which allows easy retrofit of
older designs. The internal assembly is 5"X5"X5" and weighs 3 lb.
- Control options include 24VDC Relay or "Zero Voltage Contact" closure
for ON/OFF control.
