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.
How does an ETC Catalytic Converter work?
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.
