OptiSpray™ by Yara
Like road transport vehicles, agricultural and construction machinery now use Selective Catalytic Reduction (SCR) systems to comply with emission regulations. These systems require AdBlue® to function.
However, engines that operate intermittently or under low load are prone to deposit formation in the SCR system, leading to costly downtime and maintenance.
OptiSpray® is Yara’s patented solution, designed specifically for these conditions. Developed by the world’s largest producer of AdBlue®, OptiSpray® prevents deposit build-up and keeps your machinery running efficiently.

Prevent deposit build-up
|
The Problem: Deposit Formation |
The Solution: OptiSpray® |
| Deposit build-up occurs when: | OptiSpray® contains a low concentration (<0.05%) surfactant additive that: |
|
|
| This is common in: | Based on a 32.5% urea solution, OptiSpray® meets ISO 22241 purity specifications for AdBlue®. |
|
|
| Deposits can cause blockages and engine failure, resulting in increased maintenance costs and downtime. |
Proven performance
OptiSpray™ has been tested in various conditions and at low exhaust temperatures. The product demonstrated a reduction in deposit formation in all tests, and all field test results demonstrated problem free operation. The vehicles that were tested previously used ordinary AdBlue®, and had experienced SCR back-pressure alarms at unacceptable intervals.
Proven Performance
- Tested under various conditions and low exhaust temperatures
- Demonstrated significant reduction in deposit formation
- Field tests showed problem-free operation where standard AdBlue® caused SCR back-pressure alarms
