DP 619-624 double desiccant tower dryingPrecision and modular configuration

Float block image dryer dp 619 624

Double desiccant tower models, with an airflow rate from 200 to 800 m3/h, supply air at a dew point lower than –55°C. The process air temperature can be set up to 150°C (200°C for the HT version).


Electronic control of the process temperature with self-tuning PID algorithm that ensures high precision.

Easy utilisation:
• Simple and complete operator interface
• Microprocessor control
• Large display available in the operator’s language. It shows the functioning status of the machine as well as any possible alarm or warning message
• On the main screen the following parameters of the dryer can be monitored: Drying temperature, Set-point, Dew Point value

Flexible and modular configuration:
• The operator can simply and easily increase the number of hoppers at any time. Hoppers capacity from 300 to 2500 dm³; single or centralised systems
• Intelligent Energy Supervisor: In accordance with the effective requirements of the processing machine, the IES system optimises and adjusts the energy utilisation
• Intelligent Material Drying: optimises and adjusts the energy utilisation to prevent material thermal degradation or over-drying
