Design Features

  1. Compact & Durable Construction

    • The generator set is housed in a rugged steel frame with anti-corrosion powder coating, ensuring longevity in harsh environments.

    • A weatherproof canopy (optional) protects internal components from dust, rain, and UV exposure.

  2. Efficient Engine Performance

    • The Robot RB495BD diesel engine delivers high torque at low RPMs, reducing fuel consumption and wear.

    • Turbocharging enhances power output while maintaining compliance with global emission standards.

  3. Reliable Alternator

    • The Robot RB-30-4 brushless alternator minimizes maintenance needs and provides stable power output with minimal harmonic distortion (<3%).

    • Suitable for both resistive (heating) and inductive (refrigeration compressor) loads.

  4. Advanced Control System

    • The KingPower KP610 controller offers intuitive operation via an LCD interface, showing critical parameters and alarms.

    • Supports auto-start/stop based on battery voltage or remote signals, ensuring seamless integration with truck systems.

  5. Easy Maintenance Access

    • Side panels are removable for quick access to filters, belts, and engine components.

    • Oil drain and fuel fill points are strategically placed for convenience.

Performance & Reliability

  • Cold Start Capability: The generator set starts reliably in temperatures as low as -15°C (optional pre-heat kit available for -30°C).

  • Load Response: Smooth power transition during sudden load changes (e.g., refrigeration compressor cycling).

  • Overload Protection: The KP610 controller automatically shuts down the generator if overloads exceed 110% for more than 30 seconds.

  • Vibration Isolation: Mounted on anti-vibration dampers to reduce noise and mechanical stress on the truck chassis.

Applications

The KPG38RB is designed for:

  • Refrigerated Trucks: Maintaining -20°C to +10°C temperatures for food, pharmaceuticals, and chemicals.

  • Mobile Cold Rooms: Powering standalone refrigeration units in disaster relief or event logistics.

  • Backup Power: Providing emergency power to critical systems in case of vehicle electrical failure.

  • Off-Grid Operations: Supporting remote locations without access to grid electricity (e.g., mining camps, agricultural sites).

Installation & Integration

  • Mounting: Designed for secure installation on truck chassis or trailers using vibration-dampening mounts.

  • Electrical Connection: Pre-wired for easy hookup to the truck’s battery and refrigeration system.

  • Exhaust System: Includes a stainless-steel muffler and flexible exhaust pipe for safe venting.

Maintenance & Service

  • Routine Checks:

    • Daily: Check oil level, coolant, and fuel.

    • Weekly: Inspect air filter and clean the radiator fins.

    • Monthly: Replace engine oil and filter (every 250 hours).

  • Long-Term Storage:

    • Drain fuel and add stabilizer if storing for >30 days.

    • Run the generator monthly to prevent internal corrosion.

  • Warranty: 2-year limited warranty (engine: 1 year, alternator: 3 years).

Optional Accessories

  • Soundproof Canopy: Reduces noise by 10–15 dB(A).

  • Extended Fuel Tank: Up to 300L for longer runtime.

  • ATS (Automatic Transfer Switch): Enables seamless switching between generator and grid power.

  • Remote Monitoring Kit: Allows real-time tracking of generator status via smartphone or PC.
