Market-Proven DPF Filters

State-of-the-art silicon carbide (SiC) diesel particulate filters (DPF) for a variety of applications.

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) DPF auto filters for various applications.

The optimized coatability property of the LiqTech DPF filter will aid continuous soot combustions, which will maintain the back pressure low by reducing emissions by up to 99.96 %.

Based on the requirements, e.g., durability, coatability, back pressure, service interval, and thermal regeneration strategy, we will customize the silicon carbide DPF material for optimal performance in the specific application.

In the retrofit market, DPF systems providers are challenged by legislative forces to limit the increase of NO2 from DPF systems. LiqTech provides NO2 compliant catalyzed diesel particulate filters (cDPF) for both passive and active systems.

For the 500 kW engines and industrial applications, we can deliver modular square elements in sleeving for easy implementation in your system. Based on the feedstock and gas characteristics, we will make our recommendations for coating on the particulate filter to control emissions.
