Official OEM Thermo King parts catalog entry for the Kit - Closed Loop Cooling 100609, verified by PEAK Thermo King and West Texas Thermo King Texas, Utah, Wyoming, Washington, Oregon, serving all of the USA.
Built for Performance: The Thermo King Kit - Closed Loop Cooling 100609 supports reliable temperature control for Thermo King refrigeration systems on auxiliary power units (APUs). This OEM kit engineers a sealed coolant circuit that ensures consistent engine temperature for TriPac-series APUs, improving uptime and protecting transport refrigeration components in hot and cold West Texas operations.
Thermo King refrigeration system compatibility and Thermo King engineering ensure fleets in Amarillo, Lubbock, Odessa, and the Permian Basin maintain dependable, fuel-efficient cooling and precise temperature control when truck engines are off or during extended reefing runs.
Key Features & Customer Benefits
- Closed Loop Design – Maintains an isolated coolant circuit for APU reliability and prevents mixing with tractor coolant systems.
- OEM-Grade Components – Includes expansion tank, mounting brackets, hoses, and fittings to deliver secure connections and leak resistance.
- Cold-Climate Protection – Supports Arctic operation capability and helps prevent freeze-related downtime in winter routes across West Texas.
- Improved Uptime – Enables APUs to sustain engine temperature independently, reducing dependency on truck coolant and protecting transport refrigeration performance.
- Serviceability – Designed for straightforward installation by certified technicians and for routine inspection during scheduled maintenance.
- Fleet ROI – Supports reduced repair risk and consistent temperature control to protect perishable cargo and lower total cost of ownership.
