DP 619-624 double desiccant tower dryer

These 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).

Customer oriented solutions:

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

Easy utilisation:
● Simple and complete operator interface
● Large display available in the operator’s language. It shows the functioning status of the machine as well as any possible alarm.
● On the main screen the following parameters of the dryer can be monitored: actual drying temperature, set-point, dew point value

Flexible and modular configuration:
The number of connected hoppers kan be extended at any time. The connected hopper capacity may vary from 300 to 2500 dm^³; this with 1 drying hopper or in a multi-hopper configuration. 

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: prevents material thermal degradation or over-drying.
