Duplex filters are composed of two simple filters
joined together by a valve which allows the continuous running of a filter
while the other is in a situation of "stand-by".
In this way the maintenance phase is achieved without
the need for interruptions.
Filtering elements of each filter can be represented,
depending on customers’ needs, by cartridges or baskets.
The main areas of applications are the petrochemical
industry, chemical plants, systems for water and gas treatment and refining
plants.
The construction materials
can be different: carbon steel, stainless steel and special austenitic ferritic
steels such as Duplex, Super Duplex, Nickel alloys and Titanium Gr. 2. Also the
dimensions are fully customizable.
All filters can be supplied
according to the most common international standards: ASME Sec. VIII, EN13445,
BS BS500, AD2000 and can be tested according to PED2014 / 68 / EC requirements,
supplied with CE mark and USTAMP as needed.
We
can design this type of filter for many applications: removal of solid
particles, removal of liquid particles (coalescent filters).
The
filter elements can be realized in all type of metallic and plastic materials,
polyester, needlefelt, glass microfiber.
Type
of gases: industrial, food and beverage, oxygen, hydrogen, nitrogen, air, natural
gas, etc.
Type
of liquids: industrial, water, hydrocarbon, gasoline, oil, propane, etc.
