The Thermo King SB-230 is a single-temperature transport refrigeration unit designed for trailers, widely used in long-haul and delivery applications to maintain precise temperature control for perishable goods. It’s part of the SB-series, known for reliability, efficiency, and advanced technology.
• Purpose: Ideal for refrigerated trailers transporting fresh or frozen cargo, such as produce, meat, or dairy, ensuring consistent temperatures across varying ambient conditions.
• Cooling Capacity:
• Engine Power: Up to 23,000 BTU/hr at 35°F (0°C) and 100°F (38°C) ambient temperature.
• Electric Standby: Available in standard (14 hp) or high-output (24 hp) configurations, often supporting 230V/3-phase power for stationary operation.
• Refrigerant: Uses R-404A, a common refrigerant in older Thermo King units, though newer models have shifted to R-452A for lower environmental impact.
• Key Features:
• SMART REEFER™ SR-3 Controller: Provides precise temperature management, data logging, and operational diagnostics.
• Electronic Throttling Valve (ETV): Enhances fuel efficiency and temperature control by optimizing refrigerant flow.
• SmartPower™ Electric Standby: Allows the unit to run on electric power (e.g., 230V) when parked, reducing fuel costs and emissions.
• Smooth Air™ Blower Assembly: Ensures even airflow throughout the trailer for uniform cooling.
• EMI-3000 Maintenance Interval: Extends service intervals to 3,000 hours, reducing downtime.
• Physical Specs:
• Dimensions: Approximately 83.46” (L) x 45.50” (H) x 23.26” (W) (2120 mm x 1156 mm x 590 mm).
• Weight: Around 1,500–1,700 lbs (680–771 kg), depending on configuration.
• Fuel System: Equipped with a 50-gallon aluminum fuel tank and ultrasonic fuel sensor for accurate monitoring.
• Options: Includes Whisper™ quiet technology, chrome appearance package, and remote monitoring lights for status and diagnostics.
Alternative Interpretations
If “Unit 230” isn’t the SB-230, it could refer to:
1. 230V Standby Capability: Many Thermo King units, like the Precedent S-Series (e.g., S-600) or V-Series (e.g., V-220), offer 230V electric standby options for shore power operation. These units vary by application (trailer, truck, van) but share the 230V feature for energy-efficient stationary cooling.
• Example: V-220 with 230V standby is a vehicle-powered unit for small vans, with R-134a or R-404a refrigerants and a lightweight design.
2. Typographical Error: You might mean a model like the V-220 or SB-210, where “230” is a close approximation. The V-220, for instance, is a direct-drive unit for small trucks or vans, with optional 230V standby.
Performance and Use Case
The SB-230 (or a 230V-capable unit) excels in maintaining the cold chain for perishable goods. Its diesel engine ensures reliable operation on the road, while the electric standby option (often 230V) supports stationary use at warehouses or depots, cutting fuel costs by up to 75% compared to diesel-only operation. It’s built to handle ambient temperatures up to 100°F (38°C) and is compliant with EPA and California Air Resources Board (CARB) standards when properly maintained.
