Heated Blower Desiccant Dryer GDHB233TLS

Description Heated Blower Desiccant Dryer GDHB233TLS

The GDHB models are an extremely energy-efficient, compact and reliable system for efficient continuous compressed air drying and purification in large volumes.

Technical parameters of the GDHB-TLS series:

• Regeneration type: Heated, with external blower
• Flow capacity: 8–248 m³/min
• Dew point: Down to -40 °C or lower
• Regeneration air source: Ambient air heated to 140 °C
• Compressed air loss: <2.5%
• Housing material: Corrosion-resistant steel
• Control system: Electronic, compatible with SCADA/PLC

The principle of operation of the models is as follows: after the compressor, the air is filtered and enters one of the vertical tanks, where it is dehumidified by adsorption. At the same time, the adsorbent is regenerated in the second tank. This is due to the supply of heated air from the outside by a blower, which removes excess moisture from the adsorbent. After regeneration, the heater is turned off, and the external blower cools the tower and the adsorbent with air. After that, the cycle is reversed: the tower that was previously regenerating now adsorbs moisture, and the tower that was previously adsorbing now regenerates the adsorbent.

Advantages of the GDHB-TLS series:

• The blower is located outside and uses uncompressed air for regeneration
• Energy management system (EMS) maximises energy efficiency
• Soft starters increase blower service life
• Model design ensures low pressure drop
• The heater and blower are controlled by a temperature controller to operate at maximum energy efficiency
• Increased protection class for electrical components IP54
• Additional options allow the dehumidifiers to be configured to meet individual needs of the air system

Heated blower desiccant dryers offer the state-of-the-art Energy Management System (EMS) that maximises energy efficiency while maintaining a constant dew point. By using a humidity sensor to continuously monitor the dew point, EMS minimises the compressed air used in regeneration, and optimises heater and blower operationHeated blowers are equipped with solid state soft starters that limit inrush current to ensure a smooth start and longer blower motor life.

The dryers are engineered for low pressure drop through valve selection, tower size and filter design. The heater and blower are controlled by the outlet regeneration temperature that shuts off to save electrical power once desiccant has been thoroughly regenerated. Solid state relays provide precise heater control, reduced heating times and extended heater life.

Heated Blower Desiccant Dryer with EMS can save over €20,000 in just 3 years, which is three times more than conventional dryers.
