Uitlaatgas specialist Topcats: gespecialiseerd in katalysatoren en roetfilters

We are as importer the specialist for the delivery, repair and cleaning of both typical and complex exhaust systems. Our customers are active in the automotive, transportation, logistics, construction, infrastructure, passenger transport, agriculture and marine. In 2006 we started with the Heavy Duty particulate filter distribution with as specialty low-temperature solutions. When burning soot, ash residue (among others) arises which can only be removed by the application of a particulate filter cleaning process. In 2007, we carried out the first particulate filter cleaning for both heavy duty and passenger cars. The contract for the distribution of the Pirelli particulate filters systems was closed in 2008. In 2009, Topcats introduced the first after-market direct-fit particulate filter range for passenger cars in the Netherlands. Due to the growing number particulate filter cleanings, it was decided in 2010 to purchase a cleaning machine. This particulate filter cleaning machine was the first in Europe, resulting in a professional and fast cleaning process. Since 2011 we are located at a new location with a larger warehouse and a separate cleaning department. In addition, the webshops for our European distributors was launched. Exhaust systems are becoming more and more complex, this requires specialization and product knowledge. Topcats provides optimal technical support with i.a. error codes. Since 2014, we added the widest range of particulate filters and catalysts in Aldoc. Another investment was to increase our machinery for the cleaning and rebuild of particulate filters and catalysts for machinery, trucks, passenger cars and boats. Over the year, we have cleaned more than 4.000 particulate filter and catalysts.
