  • Random Packing

    High density and excellent heat and acid resistance
    Random Packings are very common in the refinery, gas processing, chemical, and environmental process industries. Random packings have high density and excellent heat and acid resistance, and it withstands the corrosion of various inorganic acid, organic acid and organic solvents except for hydrofluoric acid.
    Used widely
    It is widely used in drying towers, absorbing towers, cooling towers, washing towers, regenerative towers and desulfurization towers in chemical engineering, metallurgy, coal gas, acid and oxygen production, pharmacy and other industries.

    Look here for Ceramic pall ring, Raschig Ring.

  • Ceramic Ball SeriesDohntec ball series products line mainly includes Inert alumina ceramic ball, Perforated Ceramic Ball, Alumina Grinding Ball, Heat Storage Ceramic Ball, Refractory Ceramic Ball which widely used in different purpose and field.
  • Molecular Sieve

    Molecular sieve is a kind of crystallized aluminosilicate .it has the characteristic of even pore diameter and large surface areas, good thermal stability, large capacity of absorption, high intensity.Speical excellent features as selective absorption, It only absorbs the molecules of which the diameter is less than the pore size of the Molecular sieve.

    Selective absorption for polar molecules and unsaturated molecules,The bigger polarity and unsaturated ratio, the stronger selective absorption.strong water absorption even in high temperature, large space velocity or low content of water, it has quite a large water absorption capacity.

    Dohntec Molecular sieve has several types of 3A, 4A, 5A,5A small oxy-enrich,13X,13XACS, IG Desiccant, Refrigerant Desiccant according to its use.

  • Honeycomb Ceramic

    Honeycomb Ceramic is porous ceramic with parallel channels triangular, square and hexagonal internals. The honeycomb units are separated by thin walls, the materials are mainly Cordierite(2MgO.2Al2O3.5SiO2), Aluminium Titanate(Al2TiO5), Mullite (3Al2O3.2SiO2), Corundum(α-Al2O3) and compound phases, etc.

    Compared with general ceramics, the materials have characteristics as: low thermal expansion, high heat shock resistance, anti-oxidation, large specific surface area and corrosion-resistance, etc. Honeycomb Ceramic is mainly used in metallurgy, tower packing in chemical industry, construction, heat-regenerative and high-temperature air purification, industrial waste gas treatment, NOx purified system in firepower plant, purified system for harmful gas rising from refuse burning, and noxious gas purification in chemical and mining industries, acting as filter and catalyst carrier used in founding process.

  • Structured Packing

    What is Ceramic structured packing?
    Ceramic structured packing is a kind of column shape and single layer corrugated packing, consisting of many moire pieces with the same geometric shape and parallel to each other. According to the different obliquity of corrugated sheet, Ceramic structured packing  is divided into X-style and Y-style.
    Used widely
    Ceramic structured packing is not only widely used in coal gas washing tower, fertilizer heat gas saturation tower, naphthalene washing tower, ammonia washing tower, but also as the support for heat exchange machine, catalyst, and suit for a big tower rebuilding/revamp.

  • Water FilterDohntec water fliter products mainly includes the Ceramic Grain Filter and Porcelain Sand Filter.
  • Activated Alumina BallActivated alumina ball has large capacity of absorption, large surface area, high strength and good thermal stability, which is widely used as absorbents, desiccants and catalyst carriers in chemical engineering, petrochemical and fertilizer industries.

Raschig Ring
Product Name:
Raschig Ring
Model:
12
Description:
Raschig ring is a form of random packing and is used in commercial fractional distillation columns to reduce pressure loss (versus using trays), while maintaining good efficiency and economy. Dohntec Raschig Ring Packing is proven in a wide range of mass transfer applications.
Pall Ring
Product Name:
Pall Ring
Model:
