SOOT PARTICULATE FILTER

The nauticleanTM filter system is based on a ceramic honeycomb structure. The exhaust gases flow through the porous honeycomb walls so that particulates are retained.

SOOT REGENERATION

Due to the sophisticated catalytic coating of the filters, soot will be continously burned off. The coating will not be affected by sulfur. For limiting the maximum ash load, sulfur content of the fuel should be below 5000 ppm (0.5%).

SCR- AND OXIDATION SYSTEM

The soot filter can be enhanced by the installation of further exhaust gas purification stages. By the installation of an SCR catalyst, the nitrogen oxides can be further reduced to requi-red limits. Oxidizing elements reduce poisonous carbon mon-oxide and hydrocarbons. All components can be combined within one single housing.

In combination with the newly developed variNOx system, the injection system can be dimensioned shorter which is making the entire system more compact.The control unit of the variNOx system measures the pollutant concentration within the exhaust gas and automatically re-gulates the dosing and injection of an appropriate quantity of reactant (e.g. AdBlue).

QUALITY

NauticleanTM products are designed to ensure low main-tenance cost and high durability. Its mechanical parts are robust, vibration and shock resistant.

The housings of the filter and DeNOx-Oxidation cartridges are made of high-grade stainless steel and allow easy access for smooth installation and exchange of the filter cartridges during maintenance intervals.

As one of very few manufacturers worldwide, Hug Engineering AG offers a complete supply of key components for exhaust gas purification that are developed, designed and produced in Switzerland. The variety covers the control systems to the soot filters and catalytic honeycombs. This assures the perfect fit and functionality in Swiss quality.

SERVICE

Worldwide spare parts supply and service are provided by Hug Engineering’s dedicated service teams.

CERTIFICATIONS

nauticleanTM systems of Hug Engineering AG correspond to all current maritime normative rules, certificates and specifica-tions (Lloyd’s Register, DNV GL , RINA etc.). Several engine groups have already been IMO Tier III certi-fied with our nauticlean systems.

GO CLEAN - WITHOUT SOOT ON DECK

SOOT REGENERATION WITH FULL-FLOW DIESEL BURNER: When average temperatures of the system remain below 350 de-grees Celsius or long idle cycles of the engine during extended lay-times in harbors, the full-flow diesel burner will guarantee an active regeneration under all operating conditions, without interrupting the operating procedure. Thanks to the fact that our full-flow regeneration system is not electrically powered, the generator‘s output is entirely available for the ships requirement.

Depending on the design of the DPF system, long operation inter-vals are possible; thus, operating costs are kept low.Besides the regeneration by a diesel full flow burner, we can also offer you attractive solutions for smaller engines or generators down to 125 kW.

EXHAUST GAS PURIFICATION FOR ENGINES UP TO 2500 KW

The exhaust gas purification system nauticleanTM not only removes soot, it also efficiently eliminates dangerous and malicious pollutants, such as nitrogen oxides and hydrocarbons.The modularly designed nauticleanTM exhaust gas purification system can be combined out of:

• PARTICULATE FILTER• SOOT REGENERATION• SCR- AND OXIDATION SYSTEM• SILENCER
