MAIN FEATURES
The HDT range is specifically designed for applications requiring ultra-low dew points, suitable for industries like electronics, pharmaceuticals, and food processing. Its key features include:
- Cold-regenerated adsorption technology for dew points as low as -70°C.
- Two-column system with adsorbent material for efficient air drying and regeneration.
- Inlet de-oiling and outlet anti-dust filters for cleaner air.
- DDC15 electronic controller for operation monitoring and maintenance scheduling, with Industry 4.0 connectivity.
- Option for dew point-based regeneration cycle management.
This setup is ideal for critical applications where standard refrigeration dryers don’t suffice.
MAXIMUM OPERATING CONDITIONS:
- Ambient temperature: + 50°C
- Inlet air pressure: 16 barg (HDT3÷25) / 10.3 barg
- Inlet air temperature: + 50°C
