Multiquip DZ118296 DEF Tank Header Assembly - OEM Replacement Part for Super Silent Generators

The DEF Tank Header Assembly is a critical emission control component that manages the Diesel Exhaust Fluid delivery system in Multiquip super silent generators. This assembly serves as the primary interface between the DEF tank and the engine's selective catalytic reduction (SCR) system, ensuring proper fluid flow and temperature regulation to prevent engine shutdowns caused by overheated DEF (at or above 150°F/65°C).

This header assembly was specifically engineered as part of Multiquip's mandatory DEF tank cover plate replacement program issued in August 2017. The update addressed critical issues where units experienced unexpected engine shutdowns due to excessive DEF temperatures. This genuine OEM assembly ensures proper thermal management of the DEF system, preventing the fluid degradation and engine protection mode triggers that can halt operations.

Compatible with the following Multiquip generator model:

• DCA220SSJU4F3

This assembly integrates with the generator's control system, which monitors fuel and fluid levels through the control panel's alarm systems. Proper installation of this updated header assembly is essential for maintaining EPA Tier 4 Final compliance and preventing costly downtime.
