Filters

Ingehim offers spiral-wound filters designed to remove solid particles from liquids and gases. These filters are equipped with proprietary in-house filtering elements.

Filter with multiple filtering elements developed by Ingehim

 

The filtering element developed by Ingehim is fundamentally innovative and possesses unique characteristics. Its filtering surface is created by a metal tape wound into a cylindrical spiral. The tape is shaped and fabricated in the form of trapezoidal waves, with the wave height increasing from the outer diameter of the cylindrical filtering surface toward its inner diameter. When winding the tape, adjacent layers firmly rest against each other at the lateral surfaces of the waves, maintaining the necessary fixed gap between the layers.

Manufacturing is already well-established for filtering elements with outer diameters of 80, 90, and 115 mm, designed for filter fineness ranging from 5 to 700 microns. The tape used is made of stainless steel or titanium, with thicknesses of 150, 200, and 250 microns and a width of 6 mm. For filtering aggressive media, filtering elements can also be manufactured using corrosion-resistant steel grades.

Filtering elements developed by Ingehim for filtration fineness ranging from 5 to 700 micron

 

Main advantages of spiral-wound filters:

– Large relative free cross-sectional area.

For example, when using a filtering element with a diameter of 115 mm to achieve a filter fineness of 100 microns, the relative cross-sectional area exceeds 41%. This allows the length of filters used in oil wells to be reduced by several times while maintaining the required filter capacity, or alternatively, it enables the filter capacity of a fixed-length filter to be increased several times.

– Ability to withstand high pressure differentials.

Being housed within a rigid metal framework, such filters retain their properties even under pressure differentials of several tens of bars. This design enables effective regeneration of the filtering elements through intensive backwashing.

– Ease of forming a filtering surface.

The filtering surface is created by simultaneously winding a metal tape and molding trapezoidal ledges onto a cylindrical surface. This method offers high productivity for filter manufacturing equipment and generates almost no metal waste during production.

 

A declaration of conformity with the Technical Regulations of the Customs Union has been granted to the Ingehim filters and filtering elements.

Ingehim is prepared to design and manufacture spiral-wound filters with a wide range of capacities and filtration fineness levels, tailored to the customer’s technical specifications.
