Vertical Leaf Filter Sulphurnet

Sulphurnet offers a full range of Dutch Engineered Pressure Leaf FiltersThese filters are high-quality systems, that can be used for numerous batch and continuous filtration processes, by client specifications and requirements.

These systems comprise of several vertical filter leaves positioned in a horizontal or vertical filter tank.

Sulphurnet’s Dutch Engineered Self-Cleaning Candle filters can be applied for either polishing applications with low solid loads or as prefilters with relatively high solid loads and can be used for manual, semiautomatic, and fully automatic operation.

Semi-automatic or fully automatic DEFS-SCCF ensures a smooth, economical, and optimal operation. To ensure these features a PLC controls the cleaning and filtration cycle based on various process parameters. PLCs are famous for their reliability, have a long lifetime, and can easily be extended to include more functionality. The DEFS-SCCF is a fully enclosed filter system and thus is improving safety, health, and environmental performance.
