3mm 4mm Copper SS304 SS316L Lab Packings Metal Triangular Fenske Spiral Filling

Product Description

Product Description

   

Triangular spiral packing, also known as triangular packing, belongs to Fenske Spiral, which is made of metal wire, and its shape is similar to that of a spring, so it is also called a triangular spring packing, which is different from a spring.

The fact is that each circle wound is not a circle but a triangle, and the triangles between the circle and the circle are staggered by a certain angle. Therefore, it is a polygon when viewed from the end face direction. This packing has high efficiency, but compared with theta ring packing, the separation efficiency is high and the resistance is slightly larger. It is mainly used in laboratories, especially the separation and refining of isotopes in the nuclear industry. The equal plate height (H.E.T.P) is about 25-58mm.

The number of theoretical plates can reach 45 per meter high, which is a commonly used laboratory bulk filler.

Our Advantages

1.Ultra high mass transfer efficiency
The triangular spiral structure forms a continuous channel with a specific surface area of up to 3500 m ²/m ³ (φ 1.5 mm), theoretical plate number of up to 70-82 pieces/meter, and equal plate height (HETP) of only 25-58 mm. It can separate difficult to separate systems with boiling point differences of 1-2 ºC.
2.Low pressure drop, high flux
Open spiral flow channels reduce pressure drop by 15-30% compared to traditional saddle packing, and increase flux by more than 10% under the same tower diameter, making them suitable for vacuum or heat sensitive material operations.
3.Strong anti blocking ability
The design of non continuous plane and staggered spiral reduces particle deposition and can operate continuously in systems containing solids or prone to scaling; The 316L stainless steel version has an annual corrosion rate of less than 0.3% in a Cl - wet H2S environment.
4.Flexible material and size
We offer specifications such as φ 1.5 × 1.5, 2 × 2, 3 × 3, 4 × 4, and 5 × 5 mm, with wire diameters ranging from 0.15 to 0.2 mm. Materials available include 316L, silicon carbide ceramic, PTFE coating, etc., to meet pH 2-12 and working conditions below 1200 ºC.
5.Modular and easy to maintain
Bulk or segmented modular design, no special tools required for installation/disassembly, laboratory small towers (diameter 15-100 mm) can be replaced within 1-3 days.
6.Long lifespan and good economic viability
The lifespan of high alumina ceramics or silicon carbide carriers can reach 15 years, and the maintenance cycle has been extended from 1 year to 8 years, resulting in a 30% reduction in overall operating costs.
7.Application
Mainly used in laboratory distillation towers, nuclear industry isotope separation, high-purity reagent preparation, phar-maceutical intermediate purification, and other scenarios with strict requirements for small batches, high purity, and high theoretical plate numbers.
