Overview: Reduce Diesel Emissions for CONSTRUCTION vehicles

Construction emission control system

Diesel emissions from construction sites is a unique problem because sites have a high concentration of exhaust in such a small vicinity. This problem extends to not just workers on-site, but also to those adjacent to the site. Proper implementation of controlled measures can help address this problem without compromising efficiency.

Most importantly, a guaranteed emission control system is fast becoming an essential component of state/provincial and municipal funded contracts.

Diesel Retrofit Options for Construction

AZ Purifier Diesel Oxidation CatalystAZ Purifier Transit Diesel Retrofit Municipality Diesel Retrofit School Bus Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Oxidation Catalyst
Manufacturer: Engine Control Systems (ECS)

DOCs utilize a chemical process in order to break down pollutants from diesel engines in the exhaust stream, turning them into less harmful components. In this diesel retrofit, an AZ Purifier is installed upstream of the vehicle's original muffler, into a single integrated package, to reduce diesel emissions by an industry-leading, verified 20-40% (40% when paired with the Racor CCV).

AZ Purimuffler Diesel Oxidation CatalystAZ Purimuffler Transit Diesel Retrofit Municipality Diesel Retrofit School Bus Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Oxidation Catalyst
Manufacturer: Engine Control Systems (ECS)

The AZ Purimuffler utilizes the same DOC technology as the AZ Purifier, combining the AZ Purifier's catalyst and a silencer solution. The AZ Purimuffler can be designed as a direct fit replacement for the manufacturer's original muffler, meaning less down time & less invasive installation. The AZ Purimuffler can reduce diesel emissions by an industry-leading 20-40% (40% when paired with a Racor CCV).

Purifilter Diesel Particulate FilterPurifilter Transit Diesel Retrofit Municipality Diesel Retrofit School Bus Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Particulate Filter (Passive DPF)
Manufacturer: Engine Control Systems (ECS)

The Purifilter was the first passively regenerating DPF to attain an industry-leading 90% emissions reduction credit value. With a honeycomb design and Silicon Carbide filter substrate, it has a higher thermal conductivity than other traditional ceramics, higher temperature toleration, and superior noise attenuation comparable to high grade mufflers. The most efficient, durable, and quiet diesel retrofit.

MINE-X Diesel Particulate FilterMINE-X Transit Diesel Retrofit Municipality Diesel Retrofit School Bus Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Particulate Filter (Passive DPF)
Manufacturer: DCL International, Inc.

The MINE-X is a flow-through particulate filter that can reduce diesel emissions and lower backpressure more effectively than conventional wall-flow diesel particulate filters. This DPF removes up to 60% DPM and requires diesel fuel with sulfur content less than 500 ppm and works best with sulfur content less than 15 ppm (ULSD).

HUSS MK Diesel Particulate FilterMK System Transit Diesel Retrofit Municipality Diesel Retrofit School Bus Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Particulate Filter (Active DPF)
Manufacturer: Huss

The MK System's active regeneration is executed by a powerful diesel burner, which works independently from the exhaust gas temperature. Depending on filter size, dpf regeneration takes between 5 and 45 minutes, supervised by the HUSS control. The high-tech LPS-SiC removes a verified 99.9% of the harmful soot particles from the exhaust gases, providing you with a dependable diesel retrofit.

OEM Replacement DPF FiltersOEM Replacement Filters Transit Diesel Retrofit Municipality Diesel Retrofit School Bus Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
DPF Filters for Maintenance
Manufacturer: DCL International, Inc.

Our aftermarket filters are brand new (not reconditioned), built as direct replacements of OEM parts for easy installation, tested to produce the same emission reductions and same backpressure as original units, and can be cleaned in the same manner as an OEM part. Purchasing a spare filter will minimize vehicle downtime, optimizing the benefits of your diesel retrofit.

Combifilter Diesel Particulate FilterCombifilter, Type S Municipality Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Particulate Filter (Active DPF)
Manufacturer: Engine Control Systems (ECS)

Best for fleets with routine operation and designated parking spots for each vehicle, the Combifilter Type S is an actively regenerated DPF system that removes 90+% of particulate matter while reducing NO2 emissions. The system includes an integrated DPF, silencer assembly, and heater element that allows the filter to regenerate in 60-90 minutes, while connected to wall-mounted unit.

Combifilter Specifications



Combifilter Diesel Particulate FilterCombifilter, Type K Municipality Diesel Retrofit Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Particulate Filter (Active DPF)
Manufacturer: Engine Control Systems (ECS)

Best for fleets without set parking spots and when downtime is just not possible, the Combifilter Type K is an actively regenerated DPF system that removes 90+% of particulate matter while reducing NO2 emissions. The system includes an integrated DPF, silencer assembly, and off-board regeneration control panel or station, which regenerates the filter in eight hours, while the vehicle is operating with a spare.

DZ Purifier DOC for miningDZ Purifier Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Oxidation Catalyst
Manufacturer: Engine Control Systems (ECS)

The DZ series was the first diesel purifier in the industry to feature quick release band clamps. This allows the center body to be cleaned when used on older engines as well as facilitate engine-out opacity checks to diagnose engine problems.The DZ catalytic converter is supported on a metallic substrate, which affords exceptional resistance to vibration and affords the lowest possible exhaust backpressure.

EZ Purifier DOC for miningEZ Purifier Mining Diesel Retrofit Construction Diesel Retrofit
Emission Control System:
Diesel Oxidation Catalyst
Manufacturer: Engine Control Systems (ECS)

The EZ series offers the same metallic substrate, catalyst, and quality materials as the DZ series but features all welded construction for an ultra compact size and lower price. EZ purifiers are ideal when retrofitting light industrial and highway vehicles, where space for installation is limited. With an add-on silencer, the EZ is the most compact and durable diesel retrofit for reducing emissions and noise.
