Thermo King SLXi-300 Refrigeration Unit

The Thermo King SLXi-300 is a slim-profile diesel refrigeration unit built for domestic refrigerated container (DRC) and rail applications, where its narrower footprint frees up an extra pallet row — 15 rows instead of the 14 a standard container holds — when paired with a new container (older containers will not reach the 15-row figure). It also weighs about 200 lbs less than a standard DRC unit, helping optimize weight distribution. Power comes from a Thermo King TK486V four-cylinder, direct-injection, liquid-cooled diesel engine rated at 24.4 hp at 2,050 rpm and compliant with Final Tier 4 EPA emissions standards, paired with a Thermo King X430P reciprocating compressor (30.0 in³ / 492 cm³ displacement, lightweight aluminum alloy body, heads, and sump). Refrigerant is R-452A, a zero-ozone-depletion-potential refrigerant, at a 12.6 lb charge. System weight is 1,620 lbs, with overall dimensions of 89.7″ x 81.7″ x 16.9″. Cooling capacity at 100°F ambient on high-speed engine operation is 46,000 BTU/hr at a 35°F setpoint, 32,000 BTU/hr at 0°F, and 19,000 BTU/hr at -20°F, with 40,000 BTU/hr of heating capacity at 35/0°F ambient and 3,230 ft³/min of airflow. Standard features include a flush-mount evaporator that reduces the risk of damage during loading and unloading, aluminum doors, stainless steel hardware, a serpentine belt system, built-in telematics capability, a rail-ready horizontal side exhaust system, and a 36-watt ThermoLite solar panel to extend battery life. Extended Life Coolant (ELC) is standard, with a 5-year/12,000-hour maintenance interval, and the EMI 3000 extended maintenance package — covering the air cleaner, fuel filter, and oil filter — pushes standard service intervals out to 3,000 hours or two years, whichever comes first.
