The self-cleaning automatic filter Bernoulli Filter is suitable for a variety of uses. It is self-cleaning and maintenance-free filter and is used to remove contamination particles from highly polluted cooling and process water as well as other fluids, e.g., from natural water sources (sea water, river water) and heating and cooling systems and processes. | |||||||||
The pneumatic operation of Bernoulli filters makes the automatic cleaning process simple and reliable with minimal mechanical wear.
The filter is supported by a control panel with a programmable logic controller (PLC), a flush valve including an actuator and a differential pressure sensor. Thanks to the flexible nozzle orientation, Bernoulli filters can be installed in almost any position, whether horizontal or vertical. Since the Bernoulli filter operates as a pressure filter, it is always installed downstream of the feed pump.
Bernoulli self-cleaning filters are designed for continuous filtration on pressure piping systems to remove particulate impurities from all types of water (such as seawater, lake water, circulating cooling water, etc.). TBNL filter based on the Bernoulli principle of innovative design, simple structure, with extremely high operational reliability.
