Thermo King Drain-Pan Front Insulating Foam S-333888
Official OEM Thermo King parts catalog entry for the Thermo King Foam, Drain-Pan Front, S- 333888, 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 Foam, Drain-Pan Front, S- 333888 supports reliable condensation management in Thermo King refrigeration systems. Engineered to seal and insulate the front edge of the drain pan, this OEM-grade foam preserves temperature integrity and helps maintain consistent operation for transport refrigeration and reefer trailer fleets.
Key Features & Customer Benefits
OEM-Quality Foam – Provides consistent sealing and thermal isolation to reduce condensation carryover and maintain temperature control.
Precision Fit for Drain Pan Front – Sits at the front edge of the drain pan to minimize water intrusion and direct condensate flow as intended by Thermo King design.
Durable Material – Resists moisture and compression to preserve sealing performance across regular service intervals.
Improves Cooling Consistency – Supports temperature control by reducing unwanted air exchange and localized icing risks.
Service-Friendly – Installs quickly during scheduled maintenance to restore drain-pan integrity and maximize uptime.
Product Details
The Thermo King Foam, Drain-Pan Front, S- 333888 is a front-positioned drain-pan foam insert specified for Thermo King transport refrigeration applications. This component serves as an insulating and sealing element at the drain pan front to support reliable condensate routing and to reduce moisture migration into surrounding compartments. Installation aligns with Thermo King drain pan assemblies and service procedures for compatible S-Series and Precedent platforms where front drain-pan foam is specified.
Efficiency & Sustainability
This foam component supports efficient, fuel-conscious cooling by helping the refrigeration system maintain designed thermal boundaries and preventing unnecessary compressor cycling. Proper drain-pan sealing contributes to consistent temperature control for perishable loads and aligns with best practices for environmentally responsible transport refrigeration, including use with Smart Reefer SR-4 and Diesel Direct Electric systems when specified by OEM guidance.
Installation & Maintenance Tips
Install using OEM attachment points and recommended fasteners to ensure secure fitment. Inspect the drain pan and surrounding seals during scheduled service intervals and replace degraded foam to prevent condensate bypass. Use Thermo King–specified maintenance procedures and parts to preserve system integrity and minimize downtime.
Real-World Applications
Use this drain-pan front foam in reefer trailers, refrigerated trucks, and transport refrigeration units to protect cargo temperature uniformity and to prevent moisture-related issues near the evaporator and drain path. Technicians at certified dealerships install this component during routine service or repair of Thermo King units.
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.
