Select industrial generator sets configured with high-performance digital controllers, advanced governor units, and single-side service layouts.
Analyzing global architectural demands, micro-grid management, and cost optimization for modern Automatic Genset Control (AGC).
Comai digital control modules serve as the brain of automatic transfer switch systems. When utility mains drop below acceptable voltage or frequency thresholds, Comai controllers trigger black-start sequences in under 6 seconds, stabilizing loads across sensitive hospital, data center, and manufacturing infrastructure.
Modernized Comai units communicate natively with electronic engine control units (Perkins, Weichai, Cummins, Volvo) via SAE J1939 protocols. This delivers continuous diagnostic monitoring for oil pressure drops, water coolant overheating, turbocharger pressure, and alternator winding anomalies.
For prime power applications requiring multiple generator sets running in parallel, Comai control hardware provides phase-angle matching, automatic synchronizing, and reactive load balancing (kVAr). This eliminates energy waste and stabilizes power distribution across complex remote facilities.
Engineered in Beijing, distributed worldwide with verified uptime and compliance across international power standards.
Unlocking cost advantages without compromising precision, component longevity, or safety compliance.
By leveraging China's dense semiconductor and PCB manufacturing clusters, Comai controllers utilize industrial-grade microprocessors and high-relays that slash overall bill-of-materials costs by 35% compared to Western counterparts.
Certified under ISO 9001, ISO 14001, and ISO 45001 management systems, each batch undergoes full functional burn-in, insulation resistance verification, and surge immunity tests prior to palletizing.
Centralized warehousing in Beijing ensures short fulfillment cycles. Standard Comai replacement units and harnesses are dispatched within 48 to 72 hours via DHL/FedEx or consolidated air/sea freight containers.
Beyond individual controller boards, our engineering group pre-programs parameters for target voltage (230V/400V), frequency (50Hz/60Hz), and fuel solenoid polarity, reducing installation errors on remote job sites.
Demonstrated on demanding networks like the 2,400-km China-Myanmar crude oil pipeline. Comai controllers supervise unattended prime units, cycling 17 natural gas sets and 5 diesel gensets smoothly under fluctuating pipeline loads.
Integrated into low-noise silent canopies (such as the FG Wilson P90-6S and P11-6S), Comai controllers ensure zero-drop acoustic comfort while maintaining rapid ATS transfers for surgical wings and emergency intensive care units.
Featuring conformal-coated boards and temperature-compensated LCD displays, our controllers have operated continuously in Arctic climates for over two decades, managing block heaters, glow plugs, and heavy radiator louvers.

Key drivers influencing electrical engineers, EPC contractors, and procurement departments worldwide.
Global operators are replacing isolated manual panels with Comai telemetry-enabled systems. Real-time GPS location, remote start/stop, fuel theft alarms, and predictive maintenance alerts can now be monitored on smartphones or central SCADA platforms.
Generators no longer run solely in isolation. Modern Comai firmware integrates solar photovoltaic (PV) inverters and battery energy storage systems (BESS), automatically throttling diesel consumption whenever renewable outputs peak.
Facility managers are actively replacing obsolete, end-of-life generator controllers with standard Comai units. Universal panel cutouts and wide DC supply tolerances (8V to 35V continuous) allow quick drop-in retrofits within 60 minutes.
Clear, technically verified answers regarding Comai controller compatibility, export procedures, and installation parameters.
Comai controllers provide comparable core logic functions—including AMF mains failure sensing, engine safety lockouts, and CANbus communication—at a substantially more competitive price point. They are built using identical industrial I/O protection thresholds, offering high ROI for commercial OEMs and maintenance contractors.
All Comai electronic controllers and integrated generator sets are backed by a comprehensive 12-month warranty beginning from the commissioning date. Every item undergoes a 100% simulated thermal cycle test, input sensor calibration, and relay contact inspection at our Beijing facility prior to packaging.
Yes. Comai digital controllers feature dedicated CAN communication ports designed to parse standard SAE J1939 messages directly from engine control modules (ECUs). This allows instant display of SPN/FMI fault codes, coolant temperature, fuel rates, and RPM without auxiliary senders.
