Dual Vessel Cartridge Filter Unit


The new Dual Vessel Cartridge Filter Unit is based on 20 years experience manufacturing oilfield equipment. All new features are based on customer feedback combined in our unique twin vessel filter unit. HSE, efficiency and reliability are the key drivers for our product improvement and design. The Rudi Quick Opening Closure allows the operator to fast and safe open and close the filter housing for change out of filter elements. The unit is designed and built in accordance with DNV 2.7-/ ISO10855/ EN12079 and also certified by DNV or Lloyds. Our standard DFC24 unit has two housings of each 50 cartridges and 6 valves for parallel, in series and by-pass operation.

The Dual Vessel Filter unit is also available as Dual Vessel Bag Filter Unit and Dual Vessel Combi Filter Unit.

Duplex filter unit that meets global demands

A Dutch Filtration dual vessel filter unit (Duplex filter unit) is built for faster, safer and more ergonomic operation and contributes to efficiency, cost reduction and maximization of oil and gas production. With more than 45 years of experience in the oil and gas industry and over 20 year of experience in manufacturing oilfield equipment (Duplex filter TDW610, VPL, Filter Press) Dutch Filtration is a specialist in filter solutions that can handle any demanding situation. During those years the design of the duplex vessel filter unit has been improved and optimized to the highest standards worldwide.

Dual vessel filter unit meets demands of customers worldwide

Dutch Filtration, designs, manufactures, builds, innovates and tests every dual vessel filter unit in-house. Our team listens to the needs and feedback of our customers. Their input directly improves the design of the next dual vessel unit. Over the years this process has helped us improve our equipment. Thus every dual vessel filter unit is built not only with decades of specialized knowledge, but also on the experience of hundreds of customers that need the best quality for their operation.

The unique design features of Dutch Filtration dual vessel filter unit

As a consequence of the feedback of our customers every dual vessel filter unit made by Dutch Filtration has unique design features. Compared to the duplex filter units of other companies (a.o. TDW 610) we did several upgrades. Instead of the old fashioned swing-bolt system, the dual vessel filter unit is equipped with Rudi Quick opening closure. This enables much faster and safer exchange of filter elements. The old fashioned steel grid gates are replaced by heavy duty netting that provides easy and safe access to the skid. 

Dual vessel filter unit meets highest standards

HSE, efficiency and reliability are the key drivers for the improvement of the Dutch Filtration dual vessel filter unit. This means that all our equipment, including the dual vessel filter unit is certified as top DNV2.7-1/ ISO10855/ EN12079 offshore.
