Everyone is aware of the debate on harmful emissions: the threshold values that determine the alarm levels. In fact, the pollutants’ emissions represent a serious problem both for the health of the environment and for the well-being of people. The highly topical issue is in the middle of many debates by public opinion and by the bodies responsible for control.

Today, thanks to the technological advancement of abatement systems, it is possible to help reduce intrinsic risks. In this complex scenario of regulations to be respected and solutions to be adopted, it is extremely important to rely on a partner who has the specific know-how and the appropriate technical skills thanks to which it can follow the customer in choosing the best solution for the specific need.

SCR DeNOx customized and designed to remove nitrogen oxides (NOx)

No intervention can be defined as a standard and it is also for this reason over the years Miretti wanted to invest in Research and Development by making use of a Technical Office (with both mechanical and electrical engineers) and a Quality Control department both within the company. Addition to the constant attention to Research, there are two fundamental levers in terms of quality and for the customer: a reliable After-Sales Service and training moments (also carried out in webinar mode).

The internal technical department of the company, made up of specialized engineers, guarantees rapid and effective answers regarding the sizing and characteristics of the proposed systems. The internal warehouse and the after-sales department ensure continuous support even after the supply of the system. At Miretti, pay attention to Research & Development is a key element.

We can provede SCR DeNOX Systems worldwide thanks to our many production facility and commercial branches located around the world: Italy, Europe, USA, South Amercica, China, Singapore, Middle East, Australia…

SCR DeNOx is designed for reducing Nitrogen oxides (NOx) in exhaust gas through conversion in Nitrogen (N2) and water (H2O). This process is named Selective Catalytic Reaction (SCR). The reaction needs ammonia (NH3) as a reducing agent, a temperature high enough and a catalytic brick wall.



OXY Metallic Catalytic Converters for several engine powers

Avaiable for several engine powers from 2kw to 4,300 kw. Miretti oxidative catalytic converters are fitted to purify exhaust gases of engine powered by methane gas (lean burn and rich burn) and diesel engines.

They are available in a vast range of dimensions and are built according to customer needs, with or without flanges.Some types – according to specific customer needs – have removable drawers for quick inspection and maintenance.

The catalytic converter is sized in relation to the engine data, the characteristics of the exhaust gases, and the maximum allowed back pressure.


Miretti Anti-Particulate Ecological Kit for Off-Road Machines (green upgrade)

With these kits it is possible to upgrade Euro 1, Euro 2, Euro 3 and Euro 4 Off-Road machines with an interesting “upgrade” in terms of reducing polluting emissions. The positive aspects can be different: first of all our health; secondly, advantages of an environmental, social and economic nature.

The adoption of the Miretti anti-pollution ecological and combined kit can represent in some cases a quick, effective end economically sustainable solution to allow off-road machines that are not necessarily new – such as Euro 1, Euro 2, Euro 3 and Euro 4 – to keep on working by making them at the same time re-enter Stage 3 A as far as emissions is concerned.
