CHENTRONICS 07000102DI High Energy Ignition Exciter

CHENTRONICS 07000102DI High Energy Ignition Exciter 100-240VAC 50/60Hz EXM 5412

The CHENTRONICS 07000102DI is a capacitive-discharge High Energy Ignition (HEI) exciter engineered for direct-spark ignition of distillate, heavy fuel oil (HFO / #6 oil), and gaseous fuels in marine propulsion boilers, auxiliary steam generators, and industrial burners. Housed inside an industrial-grade EXM 5412 ES (NEMA Type 4, 12 / IP66) gasketed steel enclosure, the unit steps up universal 100–240 VAC (50/60 Hz) line power into high-current, low-tension capacitive pulses (~2,000–2,400 VPK). Unlike conventional high-voltage inductive transformers that fail when fouled by carbon, soot, or moisture, the 07000102DI delivers an intense plasma discharge capable of burning through oil-soaked or carbon-bridged igniter tips in harsh engine-room and boiler-front environments.

Model Details

• Manufacturer: Chentronics LLC (Peabody Engineering / Hamworthy Combustion Group)
• Manufacturer Part Number (MPN): 07000102DI (Base Series: 07000102)
• Enclosure Series / Model: EXM 5412 / EXM 5412 ES (Type 4, 12 JIC Single-Door Wall-Mount Housing)
• Patent Reference: U.S. Patent No. 6,104,143
• Input Power Rating: 100–240 VAC, 50/60 Hz, 5 A Max

Features

1. Universal Auto-Ranging AC Input (100–240 VAC, 50/60 Hz): Operates across 110V, 120V, 220V, and 240V marine and shore power grids without manual tap switching or external step-down transformers.
2. Fouling-Resistant Capacitive Discharge Output: Stores electrical energy in high-voltage pulse capacitors and discharges directly across semiconductor-tipped igniters, reliably igniting heavy #6 residual fuel oil even under wet or carbon-fouled conditions.
3. NEMA Type 4 / 12 (IP66) EXM 5412 ES Enclosure: Continuously welded steel housing with robotically poured seamless gasketing and quarter-turn latches protects internal electronics against engine-room oil mist, washdown spray, vibration, and dust.
4. Isolated High-Energy Output Architecture: Separates line-side control electronics from the high-energy discharge stage to prevent electrical noise feedback into shipboard PLCs and Burner Management Systems (BMS).
5. Integrated Safety Bleed-Down Circuitry: Internal bleeder resistors safely dissipate residual capacitive charge across the output terminals once AC input power is removed.

Frequently Asked Questions

What is the difference between CHENTRONICS 07000102 and 07000102DI?

Both units share the core 07000102 100–240 VAC, 50/60 Hz high-energy capacitive discharge internal electronics. The DI suffix denotes a specific factory revision and enclosure/connector configuration housed in the NEMA Type 4/12 EXM 5412 ES steel junction box.

Can the CHENTRONICS 07000102DI operate on both 110V 60Hz and 220V 50Hz shipboard power?

Yes. The exciter features a universal auto-ranging power supply rated for 100–240 VAC at 50/60 Hz. It can be installed on vessels with either 115V/60Hz or 230V/50Hz control circuits without changing internal jumpers.

Why use a High Energy Ignition (HEI) exciter instead of a standard ignition transformer?

Standard 10,000V inductive transformers produce low current and easily short out when heavy fuel oil, soot, or water coats the spark plug. The CHENTRONICS 07000102DI delivers a high-current capacitive discharge across a semiconductor surface-gap tip, vaporizing oil and carbon deposits on contact to guarantee ignition.

What igniter tips and cables are compatible with the 07000102DI?

It is designed to drive Chentronics low-tension high-energy semiconductor igniter tips (such as 0.500-inch and 0.625-inch OD models) connected via Chentronics high-temperature coaxial/armored ignition leads. Do not use standard automotive resistive spark plug wires, as they will absorb the capacitive pulse energy.

Is the EXM 5412 ES enclosure suitable for engine room installation?

Yes. The EXM 5412 ES enclosure meets NEMA Type 4 and Type 12 (IP66) standards, sealing the internal high-voltage circuitry against oil mist, humidity, dust, and pressurized water washdowns common in marine boiler rooms.
