The products are used in a multitude of applications, covering everything from on - off road automotive engines to large stationary engines.

Core strength

particulate filters

From its facilities in Copenhagen LiqTech develops, manufactures and supplies its expanding network of sales offices around the globe. As such it retains full control of the development, manufacturing and sales process.

LiqTech lives and breathes Silicon Carbide and the material is at the core of everything we do. This enables us to provide state of the art silicon carbide (SiC) diesel particulate filters (DPF) for a variety of applications. The portfolio of catalyzed DPFs includes both precious metal and base metal coating.

LiqTech International supplies also oxidation catalysts in cordierite or metal for both automotive and stationary applications. The catalysts can be designed to remove CO, HC, and for rich operations in gas engines also NOx.
