grotamar® 82 is the first and so far the only biocide on the market, which has been approved for the usage in heating oil systems.
It has been check intensively in a 2000 hours pump test at the Öl-Wärme-Institute in Aachen, Germany. The test was successfully completed without any incidents. No adhesion on the pump or on the injector could be found. grotamar® 82 with its innovative formula protects the parts against premature oil ageing and resulting sticky remains. These sticky remains can harm the pump and the fuel injector and lead in the worst case to a complete system failure. With grotamar® 82 expensive system failures and maintenance can be avoided! This additive is also recommended against microbial contamination in heating oil.
