Diesel exhaust scrubbers come in multiple sizes
Diesel exhaust scrubbers are an effective technology for reducing emissions and improving air quality. They are used across various industries, including marine, power generation, and industrial machinery, to comply with stringent environmental regulations.
When it comes to diesel exhaust scrubbers, a one-size-fits-all approach does not exist. These scrubbers come in multiple sizes, and selecting the right size depends on several factors. Firstly, the make and model of the machine play a crucial role in determining the appropriate scrubber size. Different equipment manufacturers, such as Bobcat, Caterpillar, John Deere, and Takeuchi, may have specific scrubber requirements.
The engine specifications are another critical factor. The scrubber size can vary depending on the make, model, type, and horsepower of the engine. For instance, the clip-on style scrubber, which is easy to install and economical, is typically the size of a coffee can. In contrast, the combination muffler/purifier is designed to match the shape and dimensions of the OEM muffler on the equipment.
Additionally, the size of the outside diameter of the pipe is a consideration when choosing a diesel exhaust scrubber. A larger pipe diameter may require a different scrubber size compared to a smaller one. It's important to note that custom-engineered solutions are also available from companies like Red River, offering flexibility in addressing specific size and performance needs.
The availability of different scrubber sizes ensures that a wide range of diesel-powered equipment can be accommodated. This includes small engines and industrial machinery, such as trucks and heavy-duty vehicles. By selecting the right scrubber size, industries can effectively reduce harmful pollutants, improve air quality, and comply with environmental regulations.

They are designed for natural gas, propane and gasoline
Diesel exhaust scrubbers are designed to remove harmful pollutants from the exhaust gases of diesel engines. These pollutants include particulate matter (PM), nitrogen oxides (NOx), and sulfur oxides (SOx), among other harmful gases. By using a diesel scrubber, industries can significantly lower their emissions, thereby reducing their environmental footprint and complying with stringent emission standards and regulations.
One prominent manufacturer of diesel exhaust scrubbers is Foley Environmental, a division of Foley Industrial Engines, which is the oldest engine distributor in North America. Foley Environmental offers award-winning exhaust purifier and scrubber systems that can be used to run diesel engines indoors. Their products reduce pollutants by converting harmful exhaust gases into water and carbon dioxide, ensuring that the resulting exhaust air is safe and legal to breathe.
Another company that offers diesel exhaust scrubbers is Catalytic Exhaust, which provides a range of purifier scrubber models, including the P-Model and F-Model. These scrubbers are designed to be installed inline in the engine exhaust system and can be attached to various engines. Catalytic Exhaust's scrubbers are designed for natural gas, propane, and gasoline-fueled spark ignition engines, addressing the emissions produced by these fuel types.
It is important to note that diesel scrubbers are not limited to a single application or industry. They find use in the marine industry, power generation facilities, and industrial machinery, including trucks and heavy-duty vehicles. The versatility of diesel scrubbers makes them a valuable tool for improving air quality and meeting environmental standards across multiple sectors.
Diesel exhaust scrubbers are a critical component of emissions reduction strategies, particularly for industries that rely heavily on diesel-powered equipment. By employing advanced technologies such as filtration, catalytic conversion, and chemical treatments, diesel scrubbers effectively capture and transform harmful pollutants into less harmful or harmless gases, contributing to improved environmental compliance and air quality.

They reduce pollutants by converting exhaust to water and carbon dioxide
Diesel fuel scrubbers are an effective way to reduce harmful pollutants emitted by diesel engines. They are especially useful for industries that rely on diesel-powered equipment, helping them comply with stringent emission standards and improve air quality.
Foley Environmental offers award-winning exhaust purifier and scrubber systems that can be used indoors with diesel engines. Their purifiers reduce pollutants by converting harmful exhaust to water and carbon dioxide. The scrubbers feature a honeycomb substrate coated with a small amount of precious metal where the catalytic reaction occurs. This reaction results in exhaust air that is safe and legal to breathe.
Red River is another company that offers custom-engineered diesel scrubber solutions. Their scrubbers use advanced technologies like filtration, catalytic conversion, and chemical treatments to effectively clean exhaust gases. These scrubbers trap particulate matter, soot, and ash while converting dangerous gases like nitrogen oxides into less harmful substances.
Diesel scrubbers come in multiple sizes and styles, depending on the application. They can be installed in various ways, such as the clip-on style, inline between the muffler and manifold, or at the end of the tailpipe. The specific scrubber required depends on factors like the machine's make and model, engine type and horsepower, and the pipe's outside diameter.
Overall, diesel fuel scrubbers are an essential technology for reducing emissions and improving environmental conditions, especially in industries heavily reliant on diesel equipment.

They are used in the marine, power generation and industrial machinery industries
Diesel exhaust scrubbers are used in the marine, power generation, and industrial machinery industries to reduce emissions and comply with environmental regulations.
Marine Industry
In the marine industry, scrubbers are used to treat exhaust from heavy fuel oil, reducing the sulfur content of marine fuels to comply with the International Maritime Organization's mandatory cap enacted in 2020. According to a study by MIT researchers, using scrubbers in maritime shipping can offer environmental performance on par with, or even superior to, burning low-sulfur fuels. This has led to an increase in the number of vessels utilizing scrubbers, with over 5,800 vessels currently employing them, mainly wet, open-loop scrubbers.
Power Generation Industry
In the power generation industry, diesel exhaust scrubbers are used to reduce emissions from power plants and other applications. They help equipment operators comply with regulations set by organizations such as CARB, CAL OSHA, EPA, MOL, RICE NESHAP, and OSHA.
Industrial Machinery Industry
Companies such as Foley Environmental offer diesel exhaust scrubbers for the industrial machinery industry. Their award-winning exhaust purifiers and scrubbers allow diesel engines to be operated indoors while reducing carbon monoxide output and other pollutants. These scrubbers are easy to install and come in different styles, depending on the application.

They help equipment operators comply with regulations
Diesel fuel scrubbers are designed to help equipment operators comply with various regulations, including those set by regulatory bodies such as the Environmental Protection Agency (EPA), Occupational Safety and Health Administration (OSHA), and the International Maritime Organization (IMO). These regulations aim to reduce harmful emissions and improve air quality, protecting both human health and the environment.
By using diesel scrubbers, operators can effectively reduce dangerous concentrations of pollutants, such as carbon monoxide (CO), hydrocarbons (HC), particulate matter (PM), nitrogen oxides (NOx), and sulfur oxides (SOx). This helps them meet stringent emission standards and comply with regulations, avoiding potential penalties and fines for non-compliance.
For example, in the marine industry, diesel scrubbers help reduce emissions from ships, ferries, and other marine vessels to comply with IMO regulations and maritime emissions policies (MARPOL). Similarly, in power generation, diesel generators use scrubbers to minimize air pollution and adhere to local emission control laws.
Diesel scrubbers are also beneficial in industrial machinery, including trucks, construction equipment, and other heavy-duty vehicles, helping them meet city emissions standards. Additionally, in mining and tunneling operations, diesel scrubbers are employed to comply with regulations specific to those industries.
Foley Environmental, a division of Foley Industrial Engines, is a notable manufacturer of award-winning diesel exhaust purifiers and scrubbers.
