If a construction machine is to be operated in a zone with high nitrogen oxide pollution, it can be retrofitted with PURINOX  systems.
To ensure that retrofitting with nitrogen oxide reduction systems functions reliably, certain design adjustments must be made to the standard system in individual cases.

After retrofitting with PURINOX NOx reduction rates of 95% can be expected.

Specific information is available in our brochure PURINOX for construction machinery
