Industrial Services Supplies International has become active in 1997 as a trading company to provide local and International procurement services to its customers located in the wide industrial structure of Pakistan and then gradually expended its services from industrial indenting business to industrial repairs ,consultancies, onsite installations, relocations, trainings and contractual agreement management services.

ISSI is now successfully operating its 02 offices located in the country to cater customer's demands and requirements with right product on a right occasion. This is a young dynamic oriented company with multi dimensional experience in the field of Power Generation, Oil & Gas, Petrochemical, Oil Refining and Production Process Industries. Covering national business activities and fulfilling successful requirements of various projects ISSI is now becoming an active part of International Industrial Bidding.

Activated Alumina - 1AA
1AA is rapidly becoming the industry standard for drying compressed air and gas in both large and small dryers. PSI activated alumina is porous and spherical. It is produced exclusively for use in package dryers. 1AA material can be regenerated to its original adsorption capacity by purging with hot gas at 350° - 600° degrees.

This alumina is for both HEATED and HEATLESS/PRESSURE SWING dryers due to its inherent ease of description. Dewpoints of -100°F can be achieved depending on dryer design and operating conditions. PSI activated alumina is an excellent all-purpose desiccant for drying air and most other gases.

1/8" bead alumina is the size most frequently used in regenerative dryers - refer to 1AA18. 1/4" & 3/16" (4.8mm - 6.4mm) bead alumina are used as a pre-bed material to support large desiccant beads as a pre-buffer for silica gel beds.

Molecular Sieve
PSI molecular sieve is an alkali alumino-silicate. It is the odium form of the Type A crystal structure and has an effective pore opening of 4 angstroms. It is used to dehydrate air and gases in regenerative dryers and static drying. PSI sieves are regenerated by heating and purging. Regeneration temperatures must be 400° - 600°F, but are not to exceed 1000°F. The degree of regeneration depends on the temperature reached in purge. PSI molecular sieves are often used as a polishing layer for dewpoints to -120°F

Deliquescent Briquettes
PSI DQ11 briquettes incorporate the latest improvements in deliquescents dehydration. DQ11 is tightly compressed to provide a strong, long-lasting, dust-free product. The size and unique almond shape to reduce the bridging and channeling that occurs in dryers. PSI briquettes are 91% active ingredients for linger and more effective drying. Competitive deliquescent tablets are chemically incapable of attracting an equivalent volume of moisture.

Silica Gel Beads
PSI silica gel beads are 97% silica and 3% alumina (SGC35 is 90%/10%). This product can effectively satisfy most dryer applications, particularly the dehydration of compressed air and natural gas. The bead shape, uniform particle size and high bulk density combine to ensure optimum air/gas flow without nesting or channeling. Minimal dusting occurs due to the hard, smooth, spherical shape of the beads. These products are an excellent option for applications requiring one term economy, higher capacity, premium performance and energy savings.

Active Bed Support - ABS
Primarily used as top and bottom bed support in adsorption units.
Benefits:
  1. ABS is used worldwide as a bed support and as a hold down media to provide gas distribution and adsorption of impurities from the gas stream.
  2. ABS has the highest crush strength and most uniform bead size on the market. These features minimize dusting and breakage during loading to ensure a consistent pressure drop at all times.
  3. ABS does not have to be separated from other alumina base catalysts at time of disposal.
  4. ABS works effectively as an adsorbent while fulfilling the role as bed supports. This increase efficiency of the entire bed and certainly out performs neutral, non-active, inert materials.

Tabular Support - Alumina Balls (Tab)
  • Absorption Resistant
  • Shock Resistant
  • Heat Resistant
  • Long Life
  • Inert
  • Purity
Benefits
  1. TAB is a form of pure aluminum oxide fired at 1900°C, to remove practically all porosity and shrinkage. The properties are ideal for inert bed support.
  2. TAB minimizes side reductions that occur with other products, such as ceramic balls. High purity (>99.7% alumina) and super low silica(>0.01% silica) delivers this important feature.
  3. TAB is used as a thermal reservoir and bed support for catalysts and other refinery applications while also being used as an overburden to prevent catalyst from being carried out of the bed.
  4. TAB eliminates silica fluoride salt formation due to its high purity.
  5. TAB is used as Isomerization bed support because it has nil water adsorption to prevent destruction of the catalysts.
  6. TAB is used by various refiners as bed support for a wide variety of hydroprocessing catalysts.
  7. TAB is used in Claus reactors to permit easy disposal of all alumina products rather than screening out silica products.
  8. TAB does not produce fines or dust to contaminate the product stream.
  9. TAB is unaffected by oxidizing or reducing atmospheres.
  10. TAB is practically insoluble in most aqueous acid and alkaline solutions.
