DNT has shipped equipment for the first in China, a 6200TPD facility in Hebei.  That unit started and exceeded expectations, and DNT was granted contracts for 3 more kilns there.

DNT has tested, designed and supplied more  permanent Cement Plant SNCR systems in North America than any other Company.  

DNT has provided testing services at ELEVEN cement sites and permanent equipment at four sites in North America - using either/both urea and ammonia.  Our test equipment will define NOx reduction, reagent consumption, and optimum injection location - all leading to a simple,  cost-effective, permanent system.
