Whether for annual service with calibration of Emission Measurement Systems (NOx Analyzer) and urea consumption or - in the worst case - for a catalyst damage. We always have several m³ SCR catalysts ready for dispatch in a few days. System downtime means losses - with H+H you will optimize the system time and minimize downtime.
