Product Details
The Thermo King Expansion Valve 618115 is an OEM thermostatic expansion valve designed for Thermo King transport refrigeration systems and reefer trailers. It regulates liquid refrigerant entry to the evaporator to maintain consistent suction temperatures and efficient heat exchange. Installation follows Thermo King service procedures for secure tubing connections, bulb mounting on the suction line, and system leak testing, evacuation, and recharge using the specified refrigerant for the unit. Compatible service platforms typically include common Thermo King units found across fleet operations, including Precedent-series and Diesel Direct Electric configurations.
Efficiency & Sustainability
By ensuring precise refrigerant metering, the expansion valve supports fuel-efficient cooling and consistent temperature control across refrigerated loads. Accurate control reduces compressor cycling and improves system efficiency, contributing to lower fuel consumption during transport refrigeration runs. This component aligns with modern Thermo King service practices and integrates with fleet-level initiatives such as Smart Reefer monitoring to optimize temperature management and reduce environmental impact.
Installation & Maintenance Tips
Install the valve using OEM-approved tubing connections and soldering techniques where specified. Mount the sensing bulb with full thermal contact to the suction line and insulate it to prevent false readings. Perform leak checks, system evacuation, and recharge to Thermo King refrigerant specifications after installation. Inspect the valve during scheduled maintenance intervals and replace per service plan to preserve temperature accuracy and uptime.
Real-World Applications
Thermo King Expansion Valve 618115 suits refrigerated trailers, straight trucks, and transport refrigeration units operating in harsh regional conditions across West Texas. Fleets running long-haul reefer routes, regional produce delivery, and temperature-critical pharmaceutical transport rely on this component to maintain cargo integrity and fleet efficiency. Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.
Backed by Thermo King’s engineering and supported by certified technicians at West Texas Thermo King, this component delivers lasting reliability and uptime assurance for fleet operations.
