ETC Catalytic Converter
Oil-Free Compressed Air
Class 0, ISO 8573-1
The ETC Catalytic Converter ensures the delivery of oil-free compressed air for critical applications where air purity is essential.
The proprietary catalytic air treatment process actively oxidizes hydrocarbons into water, carbon dioxide and nitrogen, providing class 0 oil-free compressed air, according to Compressed Air Quality Standard 8573-1.
Ideal for the pharmaceutical, food & beverage, biotechnology, electronics industries, and any other industry required to fulfill stringent compressed air quality standards.
Why is an ETC Catalytic Converter Critical?
Air quality is a critical concern for many sensitive applications, such as the pharmaceutical, food and biotechnology industries, which require class 0 oil-free compressed air, according to compressed air quality standard ISO 8573-1.
Typical oil-free compressors do not remove oils suspended in ambient air, and consequently do not actually provide oil-free air. Conversely, the ETC Catalytic Converter acts independently of ambient air quality, guaranteeing the provision of class 0 oil-free compressed air in all applications.
Guarantees oil-free compressed air according to ISO 8573 Class 0
Achieves class 1 even with hydrocarbon concentrations of up to 154,000 parts per billion at the ETC inlet.
Clean condensate with a hydrocarbon concentration downstream of the ETC
Compared to many oil-free compressors, the condensate is not acidic but neutral, with a ph between 6 and 7.
Independent of the ambient air quality, compared to oil-free compressors.
Minimizes bacteria, fungus and microbial content in the compressed air.
20,000 working hours or 30 months warranty on the catalytic function.
Compatible with variable speed drive compressors operating between 110% and 20%.
Converts silicone monomers to silica and absorbs the silica.
Compact design with improved insulation and reduced energy consumption.
Electronic control unit & reduced number of electrical wear parts.
Pressure drop over ETC system approximately 5.8 psi at 100 psi.
Absolutely secure system with a protective shutdown unit that prevents oil-containing compressed air from entering the network in the event of malfunction.
The ETC Catalytic Converter uses a special catalyst to convert the oil and other hydrocarbons into water and other harmless components by a chemical-physical process, ensuring the provision of class 0 oil-free air.
The ETC is integrated into the compressed air network downstream of the compressor. The compressed air (1) containing oil that is flowing from the compressor is conducted over a pre-separation unit (2) and a VS module (3) into a plate heat exchanger (4). The pre-separation unit protects the ETC against liquid oil and water. The VS module extends the maximum working range to between 20 to 110% of the nominal flow. The compressed air is pre-heated in the plate heat exchanger and then flows into the converter vessel (5) containing the catalyst (7). By using an electric heater (6), the catalyst is held at a temperature that is necessary for the catalytic to take place. The oil-free compressed air leaves the converter and is cooled down again in a counter flow in the plate heat exchanger and is conducted through an optional particle filtration unit (8) and the minimum pressure closing valve (9) to the outlet.
