Filter candles in BOLL & KIRCH Simplex and Duplex filters
Filter candles are used in BOLL & KIRCH Simplex filters and Duplex filters. They consist of resistant, stainless-steel wire mesh with a filter fineness of 10 to 150 microns. As an option, a magnetic insert can be installed the candle element to retain finer particles of metal.
Composition of a filter candle
A filter candle contains multiple mesh candles in parallel that are placed on or screwed on and each have the same dimensions. Thus, a large filter area is created for a low construction volume. The candle insert distinguishes itself by a particularly high resistance to differential pressure. Due to the use of stainless-steel wire mesh, the filter candles can be cleaned many times and be economically used over a longer period. Primarily at high temperatures and in operating conditions in which plastics, fleece or paper are unsuitable, a candle element made from stainless steel is first choice.
Filtration of liquids
The filter candles from BOLL & KIRCH are well suited for the filtration of liquids which have a low content of solids, i. e. they are primarily used for liquids that are already very clean, e.g. for water treatment. For filtration, flow to the candle insert in the filter is from the outside to the inside, so that mechanical filtration of the surface can be carried out. Candle sieves can be adapted to the most diverse requirements of industry with practically no restrictions.
Benefits of a candle element
Compared to an inset for a jacket sieve, a candle insert stands out by a considerably larger filter area and longer service lives, also due to the few components and easier cleaning. In addition, the filter candles can be individually replaced.
For cleaning, the filter candles are easily removed from the closed-off filter chamber, manually cleaned using a liquid cleaning fluid, blown out using compressed air and inserted into the filter. Due to attachment and locating the filter element, conditional to the shape, the greatest process reliability is ensured.
