Multiple amafilter – LFC Lochem MVWDCD suitable for paraffin wax (88 m2 filtration area) in carbonsteel

At our location in Lochem, the Netherlands, approx. 120 employees are dedicated to solid-liquid-filtration. From the laboratory to the engineering department, from sales to the highly skilled welders and fabricators in our manufacturing plant. Every time we finish a filter, it is a proud moment for our team. No matter how small …or, in this case, large: the amafilter – LFC Lochem MVWDCD in carbon steel.

The application:

Paraffin wax is a white or colourless soft solid that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F); its boiling point is >370 °C (698 °F). Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons.

Paraffin wax was first created in 1830 in Germany, and marked a major advancement in candlemaking technology, as it burned more cleanly and reliably than tallow candles and was cheaper to produce.


What makes these filters suitable for paraffin wax filtration?

These pressure leaf filters (a customer ordered 4x MVWDCD-2000/1500/88 in carbonsteel) are suitable for the filtration of catalyst particles from a paraffin wax stream. The filters are carbon steel pressure leaf filters with 88 m2 filtration area. These vertical pressure leaf filters feature a half pipe heating jacket to keep the paraffin on temperature because otherwise the paraffin solidifies and will block the filter. These filters are suitable for wet- and dry-cake discharge.  The design pressure of these filters is 19 bar and the maximum design temperature is high (225 C). The filter is mounted with a special designed bottom cake discharge valve as the valve has to meet the highest industry standards. The filter is also fitted with Kalrez gaskets / O-rings to meet the suspension aggressiveness. 

Again these filters are proudly made in our manufacturing plant in Lochem, the Netherlands by Filtration Group Process Systems – amafilter – LFC Lochem.
