When working in cold climates or remote job sites, diesel equipment faces serious challenges — and DEF (Diesel Exhaust Fluid) systems are often at the center of those problems.
From frozen DEF tanks to crystallized injectors and unexpected limp mode shutdowns, DEF-related failures can halt your projects and cost you thousands in downtime.
❄️ Why DEF Systems Fail in Cold Weather
DEF starts to freeze at -11°C (12°F), which causes:
❌ Blocked DEF lines and injectors
❌ Frozen DEF tanks and pump failures
❌ SCR system faults leading to limp mode
❌ Sensor errors that force unnecessary shutdowns
Even with heaters installed, many DEF systems struggle to work reliably in freezing conditions.
🌍 Challenges on Remote Job Sites
On mining, forestry, or remote construction sites, DEF issues get even worse:
🚧 Limited access to DEF supply
🛠️ Harder to source replacement parts or technicians
💰 Extra costs from emergency repairs and towing
⚠️ Delays that impact entire project timelines
✅ The Solution: DEF Delete Emulators
A DEF delete emulator disables the DEF system electronically, allowing your machine to:
✔️ Operate at full engine power without SCR or DEF faults
✔️ Avoid limp mode and error codes even in extreme cold
✔️ Stop spending on DEF fluid refills and parts
✔️ Run smoothly without relying on DEF availability
