Mining Case Study

XYZ Salt Mine needed to control NO2 emissions from their underground equipment.  They were using Caterpillar 994 loaders and needed a retrofit solution.  They discussed the problem with AirFlow Catalyst’s engineers who visited the salt mine and drew up the specifications for two MinNoDOC units that could be added to their 994 loader.


Based on their measurements and emission requirements Airflow Catalyst built two MinNoDOCs that would great reduce NO2 output. Two units were fabricated at Airflow’s manufacturing facility in Wayland, NY.

Airflow delivered the units to XYZ salt mine and assisted in their installation.  The units ran successfully

Caterpillar 994 retrofitted with MinNoDOCs to greatly reduce NO2 output
