DES-CASE Oil Purifier: A Guardian of Industrial Equipment Focused on Oil Cleanliness
Sep 05,2025

Efficient Dehydration: Utilizing coalescence separation and dehydration technology, it effectively removes emulsified and free water from oil, capable of treating oil containing up to 20% water and breaking down any oil-water emulsions.
Precision Filtration: Utilizing precision filtration technology, it precisely removes particulate impurities from oil, achieving a high degree of oil purity and meeting the cleanliness requirements of various equipment.
Multiple Protections: An over-pressure automatic shutdown function automatically stops the oil filter when the internal pressure exceeds a set value, preventing damage from excessive pressure. An automatic drain function facilitates the timely removal of separated water, allowing for extended operation without human supervision.
Optional Intelligent Control: Optional industrial PLC controllers and touch screens are available for intelligent operation and monitoring, displaying real-time operating parameters, fault alarms, and other information, facilitating user operation and management.
Various Materials and Structures: The oil filter tank and piping are available in both standard carbon steel and stainless steel to accommodate various operating environments and oil media. The overall structure is available in various configurations, including mobile, fixed, fully enclosed, and open, to meet diverse on-site installation and usage requirements.
Principle:
Coalescing and separation principle: A coalescing filter element coalesces tiny water droplets in the oil into larger droplets, which are then separated by gravity. As the oil passes through the coalescing filter element, the water droplets are intercepted and gradually aggregate into larger droplets. Once the droplets are large enough, they settle out of the oil.
Precision filtration principle: Filter elements of varying precision are used to intercept and filter particulate impurities in the oil. The filter element has a specific pore size, allowing only oil molecules smaller than the pores to pass through, while particulate impurities larger than the pores are trapped on the surface or within the filter element, thereby achieving the desired effect of filtering impurities.
Application:
Power Industry: Used for filtering and purifying insulating oils such as transformer oil and instrument transformer oil, removing moisture, impurities, and gases from the oil, improving the insulation performance of the insulating oil and ensuring the safe operation of power equipment. Machinery Manufacturing Industry: Filters lubricants such as hydraulic oil and gear oil to extend their service life, reduce wear on mechanical components, and improve the efficiency and reliability of mechanical equipment.
Petrochemical Industry: Suitable for dehydrating and purifying light fuels such as diesel, gasoline, and kerosene, ensuring fuel quality and meeting production process and equipment requirements.
Transportation Industry: Suitable for filtering engine oil and transmission oil in vehicles such as ships and automobiles, ensuring oil quality, reducing engine failures, and extending equipment life.
