— for oil sweeping

ESCO Process's innovation allows microfiltration to take place under conditions and with superb performance not previously achievable by conventional filtration systems. ESCO Process Automatic Cleaning Stack Microfilters allow for high turndown ratio without any impact to the performance unlike conventional filtration, which requires a minimum flow to operate. This high flexibility makes operation of the ACSF a highly cost effective solution. ESCO Process ACSF is able to operate under high temperatures and harsh environments commonly encountered in most industries and are capable to separate solids from fluids at levels down to 2 microns. Accumulated solids are washed away from the ACSF as required through an automated backwash system, which require the minimal of water compared to conventional system. The ACSF is completely rejuvenated after the backwash and ready to begin the fluid filtration again at peak performance.

ACSF elements are rated nominally that indicates the filter's degree of filtration at the first instant of flow unlike conventional filtration system. The rating is based on size of the smallest assumed spherical particle that could pass through the fine filter labyrinth. This rating eliminates the trial and error in filter operation especially during the first instant of flow. Established quality control check points in the manufacturing process assure repeatable and consistent filtration rating, flow performance and dimensional accuracy.

Disc element
The thermoplastic round discs are designed with unique micro-paths on the surface to provide absolute fluid flow path when stacked together. This ensures that the fluid flows only through the fine labyrinth assuring of absolute filtration efficiency.

Discs candle assembly
The discs are stacked together to form a candle. This candle is a permanent with no disposal requirements.

Cell-pack
Multiple candles are assembled together to form a cell-pack which provide for the required fluid filtration flow rates. The cell-pack is easily lifted out of the filter vessel for cleaning and overhaul.
