Eliminate DEF Issues and Reduce Downtime for Hitachi, Doosan, and Case Excavators

In the construction industry, time is money, and equipment downtime directly impacts productivity. Heavy machinery, such as Hitachi, Doosan, and Case excavators, operates under demanding conditions where reliability is essential. However, DEF (Diesel Exhaust Fluid) system failures frequently lead to costly repairs, unexpected breakdowns, and frustrating limp mode restrictions.

One effective solution is a DEF delete, which eliminates DEF-related issues, improves machine reliability, and reduces operating costs. In this guide, we’ll explore how DEF delete kits work, their benefits, and how they help construction businesses maintain efficiency.


What Is a DEF Delete Kit?

A DEF delete kit is an aftermarket solution designed to disable the DEF system in diesel engines. The DEF system, part of the Selective Catalytic Reduction (SCR) system, is intended to reduce nitrogen oxide (NOx) emissions by injecting DEF into the exhaust. While this process helps meet environmental regulations, it also introduces complex maintenance issues for construction machines operating in harsh conditions.

Why Do Construction Machines Experience DEF Problems?

Frequent DEF sensor failures – Leading to limp mode and downtime.
High maintenance costs – NOx sensor replacements cost around $1,100, while DEF control units (DCU) can exceed $6,000.
DEF freezing issues – DEF crystallizes in cold temperatures, causing system malfunctions.
False error codes – DEF system errors often persist even after repairs.

By installing a DEF delete kit, operators can bypass these common DEF failures, ensuring their excavators, crushers, and loaders remain fully operational.


Key Benefits of a DEF Delete for Heavy Machinery

1️⃣ Reduced Downtime & Increased Reliability

DEF system failures can cause unplanned machine shutdowns, leading to work stoppages and financial losses. A DEF delete kit removes the complex and failure-prone SCR system, preventing limp mode restrictions and keeping your equipment running smoothly.

2️⃣ Significant Cost Savings

Eliminate DEF purchases – No need to constantly buy Diesel Exhaust Fluid (DEF).
Lower maintenance costs – No more replacing expensive NOx sensors, DEF pumps, or injectors.
Avoid costly dealer repairs – Many main dealers struggle to fix persistent DEF problems, leading to unnecessary replacements and service fees.

3️⃣ Improved Engine Performance & Efficiency

Engines run more smoothly without DEF-related restrictions.
No unnecessary fuel consumption due to DEF regeneration cycles.
Excavators and loaders perform better in demanding conditions.

4️⃣ Easy Installation – No Exhaust Modifications Needed

No need to remove the DPF (Diesel Particulate Filter).
No need to modify the exhaust system.
Plug-and-play installation – Takes only 30-45 minutes with full support.

Our DEF emulator ensures that the engine’s ECU registers the SCR system as fully functional, preventing error codes, limp mode, and shutdowns.


How Our DEF Delete Kits Work

Once installed, our DEF delete module:
Disables the SCR system – Your machine will no longer require DEF fluid.
Deactivates NOx sensors – Eliminates costly sensor replacements.
Prevents limp mode – Keeps your machine fully operational.
Stops DEF system error codes – No more false alarms or warning lights.

This modification is completely reversible—if you sell your machine, you can transfer the emulator to another compatible model.
