• Fuel System: Equipped with a biodiesel-compatible fuel tank (e.g., 245L Schmitz plastic tank with one filling neck).
• Chassis and Axles: Often paired with trailers featuring SAF axles, disc brakes, and air suspension for stability and durability. Tire size is typically 385/65 R22.5.
• Weight: When integrated with a trailer, the empty weight is approximately 9,110–9,420 kg, with a gross vehicle weight (GVW) of up to 35,000–36,000 kg.
• Insulation: Features high-performance insulation panels (e.g., NX17 foam, 45 mm wall thickness) for optimal temperature retention.
• Engine: Powered by a Thermo King refrigeration engine, compliant with emission standards (e.g., Euro 0 for older models, though newer units may align with stricter regulations).
These specifications make the SLXi300 suitable for demanding transport scenarios, ensuring reliability and compliance with industry standards.Buy Used Thermo king Slxi300 Online
3. Key Features and Technologies
The SLXi300 incorporates several advanced features that distinguish it in the transport refrigeration market:
• BlueBox Telematics: The SLXi300 includes Thermo King’s BlueBox system, a connectivity platform that provides real-time data on temperature, unit performance, and location. This enables fleet managers to monitor cargo conditions remotely, ensuring compliance with food safety and pharmaceutical regulations.
• OptiSet and Modulation: The unit features OptiSet, a pre-programmed temperature control system that optimizes cooling based on cargo requirements. Electronic temperature modulation ensures precise control, reducing energy waste.
• SMART Technology: The SLXi300 uses intelligent management systems for refrigeration performance, monitoring, and connectivity. This enhances temperature control accuracy and provides real-time data for operational efficiency.
• Hybrid Capability: The diesel-electric configuration allows the unit to operate on electric power when stationary (e.g., at loading docks), reducing fuel consumption and emissions.
• Whisper Pro Option: The SLXi300 Whisper Pro variant is designed for low-noise operation, making it ideal for urban deliveries or noise-sensitive areas.
• CargoWatch Sensors: Equipped with two temperature sensors for precise monitoring, ensuring cargo integrity throughout the transport chain.
• Sustainability Features: The unit supports biodiesel and integrates with sustainable technologies like high-voltage batteries and solar panels (available in the broader SLXi series).
These features position the SLXi300 as a forward-thinking solution for modern refrigerated transport, balancing performance with environmental responsibility.Buy Used Thermo king Slxi300 Online

4. Applications
The SLXi300 is used in a variety of applications, including:
• Food Transport: Ensures safe delivery of perishable goods like fruits, vegetables, dairy, and frozen products. Its precise temperature control is critical for maintaining quality and meeting regulatory standards.
• Pharmaceutical Transport: The unit’s ability to maintain consistent temperatures and provide real-time monitoring makes it suitable for transporting vaccines and other temperature-sensitive medical supplies.
• Intermodal Transport: Designed for seamless integration with intermodal systems, including road, rail, and marine transport, ensuring cargo integrity across multiple modes.
