Why choose Dinex DiSiC_HP?

A unique reaction-formed High-Porous Silicon Carbide particulate filter

The unique pore structure of the DiSiC_HP ensures a low back pressure at a high particle number (PN) filtration efficiency. This is achieved by combining a low pore size of 8 – 9μm with a high porosity of 54 – 57 %. The small pores below 10μm lead to a fast buildup of a soot cake layer on the inlet surface of the filter wall and reduces deep bed filtration. This leads to the effect of a low PN emission in all soot loading conditions and driving cycles. The porosity above 54% ensures the low back pressure.

Benchmark tests against 4 competing Silicon-Carbide (SiC) technologies, shows that Dinex gen. III DiSiC_HP has…

… the highest PN filtration efficiency, both loaded and unloaded

• Future-proof regulatory compliance (Euro 7, BS7, Stage VI, Tier 5 & equivalent) • Low PN emissions in every situation (Fresh state, during regeneration, and right after)

… a low back pressure level throughout all operating conditions

• Reduces fuel consumption • Increases peak power output

… a strong & durable design, yet low-weight & easy to regenerate

• Capable in a wide range of applications and challenging conditions • Lower weight & faster SCR heat-up

DiSiC_HP Application Examples

On-Road - Light, Medium and Heavy Commercial

Application demands

Compliance to upcoming regulatory requirements: Lower PN emissions,& particles down to 10 nm
Low fuel consumption

Why Dinex DiSiC_HP

High porosity (54%) and low pore size (8,0 μm) results in the market’s best PN filtration efficiency in all conditions.
Low back pressure in both loaded and unloaded state, and light-weight design.
Low thermal mass allows for more heat to be preserved for the SCR.

Off-Road - Construction & Agriculture

Application demands

Durability in harsh working conditions
Flexibility to endure both long periods without regeneration, and sudden peak engine power outs.

Why Dinex DiSiCHP

Less likely to break from thermal tension thanks to low elastic modulus (9,0 GPa).
High soot load capacity of up to 8,0 g/l, without affecting back pressure, thanks to thicker walls (300 μm) and higher porosity (58%).
Earlier and faster passive regeneration, thanks to a low thermal mass.

Special applications - SCR-on-Filter & Large/Stationary

SCR-on-Filter

High porosity allows for more SCR coating to be applied, without
significantly affecting back pressure
Lowers the risk of urea deposits in the substrate

Large/Stationary

High soot load capacity allows for longer period of efficient
performance without regeneration.
Low thermal mass allows for faster heat-up to initiate regeneration.
