Products & Solutions:

Petrotat 4A Molecular Sieve is a synthetic crystalline aluminosilicate with a regular micropore structure.; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

Petrotat activated alumina is a smooth sphere of activated alumina produced by  unique manufacturing process. Activated Alumina is an excellent desiccant for drying a wide variety of liquids and gases. Although all molecules are adsorbed to some extent on activated alumina, those molecules having the highest polarity are preferentially adsorbed. Stream conditions such as pressure, concentration and molecular weight of the molecules, temperature and site competing molecules affect the efficiency of adsorption. Activated Alumina is especially sutaible for heatless (PSA) air dryers.

  • Low Pressure Drop
  • High Surface Area
  • Long Lifetime
  • High Water Adsorption Capacity
  • Deep Drying
  • High Crushing Strenght
  • Low Abrasion Loss
  • Maximum Dew Point: – 70 (PSA)

Alumino Silicate gels in the form of hard, spherical beads. They are essential in removing water from compressed air so that the efficiency of chemical processes is not compromised. this is the most energy saving and environmentally friendly adsorbent available for the air compression industry.

  • Large surface area, which leads to a larger adsorption capacity
  • Low desorption temperature, which decreases the amount of energy used in regeneration
  • Ability to achieve low pressure dew points
  • Long lifetime due to its abrasion resistance and mechanical and thermal stability
  • Maximum Dew Point: – 60 (PSA)
  • Required Regeneration Temprature: 120 – 150 C

With Alumino silicate gels you save:

  • 15% in energy due to low desorption temperatures
  • 5% in energy due to high dynamic capacity
  • 25% to 40% on refills due to long life span

VAYUSORB™ 6004  is a 4.0 mm pellet activated carbon suitable for air & gas purification, solvent recovery, industrial odor removal & VOC treatment. The cylindrical pellet shape provides a lower pressure drop & is having excellent resistance to mechanical and thermal stress due to its high hardness. VAYUSORB™ 6004 is manufactured from high quality anthracite coal having quite low ash thus less impurities solvated in liquid phase application.

  • Low Pressue Drop
  • High Adsorption Capacity
  • High Surface Area
  • World Class Quality
  • Made in India
