MAIN FEATURES
The AHT range efficiently integrates key components (pre-cooler, separator filter, refrigeration dryer) into a single unit, utilizing ACT range technology. Features include:
- Combined heat exchange coil (copper and aluminium) for effective cooling.
- Pre-filter with automatic condensate drain.
- Compact vertical layout to save space.
- High operational limits.
- Industry 4.0-ready electronic controller.
- Efficient condensate drainage with two separate devices.
This design ensures a minimal footprint and optimal performance for compressed air treatment.
MAXIMUM OPERATING CONDITIONS:
- Ambient temperature: + 50°C
- Inlet air pressure: 16 barg (ACT3÷18) – 14 barg
- Inlet air temperature: + 100°
