Factory directly Pre-insulated Duct - Rooftop Air Handling Units AHU – Holtop

Ceiling AHU combined with the technology of ceiling heat recovery ventilator (HRV), aim at the compact installation and energy efficiency for all budiling. Airflow range 800~10,000CMH.

AHU Overview

Rooftop Ceiling Suspended AHU Features

1．- Compact design, ultimate low height, reducing the lifting space occupied.

2．- Independently research, develop and produce heat recovery components, achieving sensible heat or total heat recovery with excellent energy-saving effects.

3．- Constructed by sandwich panes with optimal thermal and noise insulation performance.

4．- High efficiency heating/cooling coils to ensure good heat exchange performance while reducing air resistance to reduce fan power load.

5．- The internal air channel design is optimized to improve the air supply capacity.

6．- Two-way ventilation, introducing outdoor fresh air while expelling indoor stale air to improve indoor air quality.

7．- Flexible combinations, coarse filter or medium filter and bypass or wet film humidifier are optional to meet different user requirements
