Product Description

Key Features & Benefits

Unique Circular Design
Hexagonal shape with a circular heat exchanger for efficient 360° operation and a discrete appearance.
6-Directional Airflow
Output slats distribute heated air evenly in six directions, ensuring maximum thermal comfort across the entire area.
Fan Choice (AC or EC)
Available with standard AC fans or high-efficiency EC fans for better energy savings and control.
Fast Heating Performance
Designed specifically for quick heating of large industrial interiors, reducing warm-up times.
Powerful Heat Exchanger
Triple-row Cu/Al coil (max 90°C/1.6MPa) with a built-in power reserve for reliable operation.
Discrete Aesthetic
Zinc-coated casing with RAL 9010 varnish offers a clean, industrial look suitable for various spaces.
