Project History
Kali+Salz has tested various DPF systems in the past
Kali+Salz required an efficient system with long service intervalls
A GHH LHD (12.2) was selected for a 1,000 hour test
Installation on 30. AUG 2007
Final Report on 10. JAN 2008
6
K+S System Requirements
DPF must not increase NO and NO2
DPF resistant against salt dust in air
Automatic regeneration during operation
Long service interval min. 1,000 hours
Ambient air temperature between 20 and 50°C (122 F max)

Test Results – SUMMARY Temperature and Back Pressure
Even after 2,500 operating hours without cleaning maintenance
Max. backpressure pmax: 62 mbar (@ 1,841 h)
highest exhaust gas temperature:
498°C upstream,
407°C downstream of the filter.
The temperature threshold of 380°C required for the correct (regeneration)
function of the filter using an additive system is reliably achieved.
