Protection of heat exchangers / filters for heat exchangers

Heat exchanger filters are essential to guarantee maximum lifespan of your heat exchanger. A self-cleaning filter is very suitable for protecting heat exchangers. Below you can read how a self-cleaning filter works and what other filters for heat exchangers exist.  

Self-cleaning filter 

A self-cleaning filter works on the Bernoulli principle. Inside the filtration system is a basket that retains solid particles. Part of this type of filter system is a disc that is mounted on a pneumatic cylinder, so the basket can be cleaned automatically and in a 'contactless' way. As with any filtration system, the liquid flows through the filter towards the outlet of the filtration system, while the solid particles are retained by the filter. As soon as the filter basket becomes saturated with particles and a preset differential pressure is achieved, the self-cleaning system starts its’ work. The pneumatic cylinder pushes the disc past the filter basket and causes an updraft. As a result, the solid particles are detached from the filter basket and are directed to a designated outlet. This cleans the basket, so it can retain a new batch of particles again. The advantage is that this system can be set up fully automatically, so no maintenance is required. In addition, the disc does not come into contact with the filter basket itself, so there is no wear on the filter, which benefits its lifespan. In short, it is ideal as protection for heat exchangers. 

A success story of Van Borselen Filters

Van Borselen Filters has been able to offer a wonderful solution to one of our customers. The customer was looking for filters for heat exchangers to protect them from the forces of the sea. The aim was to filter seawater and stop sand and shellfish at a flow of 4000m3 per hour. A fully self-cleaning filter made of Fiberglass Reinforced Polymer (FRP) and with an inlet and outlet DN700 was manufactured and delivered to the customer. From concept to realization, Van Borselen fully supervised this project. From manufacturing control, a Factory Acceptance Test (FAT), to final delivery, we made sure that every detail met the highest standards and customer requirements. 

Other filters for heat exchangers

A self-cleaning filter can be fully dimensioned to the required flow per hour. Of course, there are also other types of filters to protect heat exchangers. Another suitable filter for the protection of heat exchangers is a High Flow filter. Typical High Flow filters are made of polypropylene or fiberglass and have a length of 40 or 60", which corresponds to a maximum flow per hour of 120m3. If desired, several of this type of filter can be placed in one housing at the same time to increase the maximum flow. Whatever the customer's wishes, Van Borselen Filters B.V. supplies filters for your heat exchangers.
