Gardner Denver was founded in 1859, is one of the first air compressor system corporations and one of two corporations that owns many brands. air compressor world's best. Gardner Denver offers varieties High efficiency air compressor. Gardner Denver Air Compressors & Air Dryers & Air Filters Mainly used for automatic machinery in areas requiring high precision, harsh and dangerous working environments.

Absorbent air dryer brand Gardner Denver, Germany.

I. What is an Absorption Air Dryer?

Depending on the environment and installation location of the air compressor, compressed air (compressed from outdoor air) will contain a certain amount of impurities such as dirt, water and possibly oil vapor (for this type of air compressor). oil-filled air compressors)... and then it can have some impact on equipment that uses compressed air to produce quality products, especially mechanical manufacturing, steel, corrugated iron, and embedding factories. plating, coating, garment, coffee, cashew nuts, etc. Therefore, most factories with high requirements for output compressed air quality use compressed air dryer systems to separate water and dry. and clean compressed air before supplying it to the equipment used.

II. Gardner Denver Absorption Dryer Operating Principle.

Absorption air dryer Mainly consists of two absorption towers filled with desiccant particles (Molecular). When compressed air passes through the absorption tower, water will be absorbed by the desiccant particles, thereby achieving the purpose of drying the compressed air. The two towers perform drying and regeneration alternately through the airflow conversion valve so that the desiccant particles can be regenerated.

III. General Features of Gardner Denver Absorption Dryer.

• High absorption capacity and long life thanks to the use of highly effective active auxiliary desiccant particles.
• Stable gas source output quality is guaranteed by the intelligent control system of the single-chip microprocessor system, which has the function of switching at the appropriate time.
• The unique tank structure design can preserve 98% of the absorbed heat, thus improving desorption and allowing more thorough regeneration.
• The superior air distribution design allows air to pass through the absorption layer evenly, thereby avoiding the formation of voids.
• High quality pneumatic switching valve with responsive operation and reliable performance.

IV. Machine Model

Absorption dryers are classified into two types: non-heat type (HEATLESS) and heat type (HEATED), depending on the process used. The basic difference between these two types lies in the method of removing moisture from the desiccant, also known as the absorption granule regeneration process.

A. Heatless Absorption Dryer – HEATLESS

This process regenerates the adsorbent by introducing a quantity of dry compressed air. After absorbing moisture, this compressed air is discharged outside. This type of dryer requires separating a portion of the dry compressed air from the system to perform the desiccant regeneration process.  Alternating 2 towers Although no external power source is required, resulting in a lower initial investment, the operating costs of this type of dryer are relatively high.

• Flow: 1.1 to 127m³/minute
• Rated working pressure: 0.7 MPa
• Maximum working pressure: 1.0 MPa
• Maximum intake air temperature:
• Pressure dew point: for two types of products
• Regenerative air consumption: 14%
• Low initial investment cost
• No external power source
• Run at low temperature
• Safe and reliable
• Recommended application places: small flow, intermittent air use. Remote control, power plant or laboratory, etc.

B. Heat Absorption Dryer (Resistance) – HEATED

This dryer operates similarly to a non-thermal absorption regenerative dryer, but the compressed air from the system will be pre-heated by an efficient external heater (thermal sensor) before entering the regenerative tower for regeneration. create a desiccant. The fact that compressed air is heated helps it absorb more moisture. Although the initial investment cost of this type of dryer is relatively high due to the need to equip a heater and related accessories, the operating costs are lower thanks to the reduction of renewable gas consumption.

• Flow: 1.1 to 145m³/minute
• Rated working pressure: 0.7 MPa
• Maximum working pressure: 1.0 MPa
• Maximum intake air temperature:
• Pressure dew point: for two types of products
• Regenerative air consumption: 8%
• Low operating costs
• Renewable air consumption is less
• Large air flow volume used
• Lower dew point pressure
• Recommended application places: high flow, continuous air use, drier compressed air requirements, available external power source, etc.
