Media Products, Applications and Characteristics |
 |
Please Choose from the following:
|
|
|
Applications
- Premium grade is sifted for precise bead size and formulated for optimal moisture removal for critical applications
- Extended Life Grade is best suited for heat regenerative dryers where high heat and humidity may age industrial grades.
- Industrial Grade is desiccant of choice for most air drying applications
|
|
Characteristics
- High absorption capacity over a wide range of RH provides optimal moisture removal
- High crush strength and low abrasion loss minimizes dusting due to handing and pressure swings in heatless air dryers to yield superior desiccant of choice for most air drying applications.
- Uniform bead size prevents clogging of manifolds and screen minimizes bed pressure drop.
- Wide pore size distribution enhances desorption, an important product characteristics for heatless in dryer application.
- Alumina regenerates easily at low temperatures making it well suited for heatless air dryers.
- Industrial grade Activated Alumina will hydro-thermally "age" more rapidly when exposed heat at high humidity. For heated dryers use extended life grade, it is re-hydration resistant, making it thermally resistant.

Applications
- Final polishing layer internally heated desiccant dryers ( 40 degree fahrenheit and 100 degree fahrenheit)
- Applications involving the exclusion of certain molecules from the absorption surface. e.g. drying natural gas with minimal odorant removal.
- Liquid drying application (ethanol, methanol, etc.)
- Superior performance when the air has been pre-dried, often used at the outlet end of the heatless dryer vessel when air must be dried very low dew points (-100 fahrenheit range)
|
|
Characteristics
- Higher adsorption capacity at lower relative humidity than either activated alumina or silica gel.
- Lower adsorption capacity at high relative humidity
- Requires higher temperature for regeneration than does silica gel or activated alumina.
- "Sieves" molecules based on size and configuration thus molecular sieves are used to absorb specific molecular types
- CNG II - Molecular Sieves designed specifically for natural gas application.

|
Silica Gel Applications
- High capacity and hydro-thermal stability make silica gel a good choice for internally heat regenerative dryers in combination with a polishing layer of molecular sieve.
- Best used with a layer of activated alumina or water resistant silica gel at the bed inlet to minimize the possibility of liquid water reaching the silica gel.
|
|
Silica Gel Characteristics
- Highest adsorption capacity in heat regenerated dryers due to high loading rates and relative humidity (approximately 15% greater than alumina)
- Breaks down in the presence of liquid water
- Highly resistant to hydro-thermal aging promoting longer desiccant life.
- Lowest regeneration temperature requirements lowers the energy cost of heating the bed.
|
Water Resistant Silica Gel Application
- Buffer layer for silica gel beds
- Long term hydro-thermal stability makes water resistant silica gel a good choice for heat of compression and other heated dryers that are regenerated at pressure.
|
Water Resistant Silica Gel Characteristics
- High adsorption capacity over a wide range of relative humidity provides optimum moisture removal.
- will not break down in the presence of liquid water
- Highly resistant to hydro-thermal aging providing longer life in heated desiccant dryers.
|
|
|
|
|
Applications
- Non-adsorptive material used to prevent smaller desiccant beads from obstructing the lower desiccant retaining screen.
- Used in the lower vessel head to promote even flow distribution, reduce pressure drop and minimize channeling
- Placed at the top of the desiccant bed to promote even flow distribution and prevent fluidization of the active desiccant
|
|
Characteristics
- Virtually no adsorption capacity
|
|
|
|
|
|
Applications
- Polishing layer for odor and oil vapor removal commonly used in breathing air, semi-conductor and pharmaceutical applications
- Removal of mild caustics / acids detrimental to desiccant performance
- Used in conjunction with higher adsorption materials prior to the carbon.
|
|
Characteristics
- Very high capacity for organic vapors making it the choice for odor free applications
- Oil vapor removal capability
- Odor removal capability
- Removal of a broad range of contaminants
|
|
|
|
|
Applications
- Drying natural gas in remote field locations
- Non-critical portable drying applications, e.g. for sandblasting
- Short term non-continuous demand applications
|
|
Characteristics
- Constant performance over a long life span
- Good dew point suppression
- Dissolves evenly removing moisture from the air stream until the tablets are slowly consumed thus no regeneration energy source is required.
- Will not react with common airborne contaminants
