AdBlue for a mining hauling fleet must meet ISO 22241, remain free from contamination, and perform without crystallization or SCR faults. In this national fleet trial, TERRAGARD DEF from PT Beta Pramesti Asia maintained 32.5% urea concentration, stable consumption, and operation without SCR-related downtime.

Challenge
A national mining company required a reliable Diesel Exhaust Fluid solution for its continuously operated, high-load hauling fleet.
The solution needed to maintain Selective Catalytic Reduction system reliability, prevent equipment downtime, and support compliance with Euro IV-equivalent nitrogen oxide emission requirements.
The company also needed to minimize the risk of DEF crystallization, injector blockage, corrosion, deposits, and SCR system faults. Any failure in the emission control system could interrupt mining operations, damage critical engine components, and expose the company to potential regulatory penalties.
Results
Following a controlled field trial, TERRAGARD DEF demonstrated compliance with ISO 22241 requirements and supported consistent SCR system performance.
The main results included:
- NOx emissions remained within the applicable Euro IV-equivalent regulatory limits.
- DEF consumption remained within the OEM operating range of approximately 3–5%.
- Urea concentration remained at the required 32.5%.
- No SCR-related fault codes were recorded.
- No crystallization was found on the dosing nozzle or injector components.
- No signs of corrosion or material degradation were observed.
- Diesel and DEF consumption remained stable.
- No operational downtime was attributed to the emission control system.
The trial confirmed that TERRAGARD DEF is a reliable, safe, and cost-effective option for heavy-duty mining fleets requiring stable emissions-control performance.

TERRAGARD DEF AdBlue for diesel fleets
About the Customer

The customer is a leading national mining company operating a large fleet of heavy-duty hauling equipment.
Its mining operations run under continuous and demanding load conditions. The company is committed to maintaining equipment reliability, operational efficiency, environmental sustainability, and regulatory compliance across its fleet.
The Challenge
Operating heavy-duty hauling equipment under continuous load placed significant pressure on the company’s emission control systems.
The fleet was required to meet stringent Euro IV-equivalent NOx emission standards without compromising equipment availability or operational efficiency.
Inferior or inconsistent DEF products could potentially cause:
- SCR system fault codes.
- DEF crystallization.
- Dosing pump or injector blockage.
- Corrosion of emission system components.
- Unplanned equipment downtime.
- Increased maintenance expenses.
- Non-compliance with emission requirements.
- Financial penalties or operational restrictions.
The company therefore needed a technically reliable DEF product capable of maintaining SCR system stability in intensive mining conditions.
The Solution
After evaluating several Diesel Exhaust Fluid suppliers, the company selected TERRAGARD DEF/AdBlue from PT Beta Pramesti Asia.
The product was selected based on its:
- ISO 22241-compliant formulation.
- Standardized urea concentration of 32.5%.
- High-purity raw materials.
- Low mineral and contaminant content.
- Compatibility with SCR system components.
- Non-corrosive formulation.
- Technical documentation and safety profile.
A controlled trial was conducted on several heavy-duty hauling units.
During the trial, the technical team monitored:
- DEF consumption.
- Diesel consumption.
- SCR system status.
- Dosing pump operation.
- Injector and nozzle condition.
- Equipment fault codes.
- Signs of crystallization.
- Signs of corrosion or material degradation.
- Overall equipment availability.
The trial was designed to ensure that TERRAGARD DEF could support emission reduction targets without negatively affecting fleet productivity.
“TERRAGARD DEF/AdBlue proved to be a reliable solution, supporting our emission reduction targets without causing any operational disruption during the trial.”
The Results
The field evaluation confirmed that TERRAGARD DEF maintained stable SCR system performance throughout the trial period.
DEF consumption remained within the OEM-recommended range of approximately 3–5% of diesel consumption. The product also maintained the required urea concentration of 32.5%.
NOx emissions consistently remained within the applicable Euro IV-equivalent regulatory limits.
Visual and technical inspections found:
- No SCR fault codes.
- No nozzle or injector crystallization.
- No corrosion on emission system components.
- No abnormal dosing pump operation.
- No material degradation.
- No SCR-related equipment downtime.
Diesel consumption remained stable, while the fleet continued operating without disruption related to the emission control system.
These results demonstrated that TERRAGARD DEF provides both operational and economic value by helping the mining company protect critical SCR components, maintain equipment uptime, and support regulatory compliance.
Operational Benefits
Reliable SCR Performance
The SCR systems remained stable throughout the trial without triggering fault codes or warning indicators.
Reduced Downtime Risk
No operational interruptions were attributed to DEF quality, crystallization, corrosion, or SCR system failure.
Consistent DEF Consumption
DEF consumption remained within the equipment manufacturer’s recommended operating range.
Component Protection
No corrosion, deposits, or visible degradation were found on dosing pumps, injectors, nozzles, or related components.
Emission Compliance
NOx emission performance remained within Euro IV-equivalent regulatory requirements.
Lower Operational Risk
The product helped reduce the potential costs associated with maintenance, equipment downtime, component replacement, and regulatory penalties.
Customer Testimonial
“As a mining company operating intensive, high-load hauling equipment, we needed a DEF solution we could truly rely on—not only to meet emission standards, but also to maintain SCR system stability and prevent costly downtime.
After completing the trial, TERRAGARD DEF/AdBlue proved its quality. We experienced zero fault codes, no crystallization, and consistently stable SCR performance throughout the evaluation.
Our DEF and diesel consumption remained consistent, there were no signs of corrosion on system components, and most importantly, there was absolutely no operational disruption.
This product delivers real value to our operations, both in terms of efficiency and regulatory compliance. We are satisfied with the results and consider TERRAGARD DEF a safe, effective, and long-term solution.”

What data should a fleet prepare before an AdBlue trial?
Prepare the unit and OEM list, operating hours, diesel and DEF use by unit, SCR fault codes, crystallization history, tank capacity, site lead time, and receiving and transfer procedures. This baseline allows the trial results to be compared consistently without replacing OEM limits or procedures.
