Frequently Asked Questions

What are the main advantages of this vertical air handling unit?

Unlike suspended ceiling units, this floor-standing vertical air handling unit saves overhead space and is much easier to maintain. It is particularly suitable for mechanical rooms, basements, or areas where ceiling height is limited.

What is the cooling capacity of this air handling unit under return air and fresh air conditions?

Under the return air condition (27/19 °C) the cooling capacity is 61.0 kW, while under the fresh air condition (34 °C dry-bulb / 28 °C wet-bulb) it reaches 131.0 kW. Both ratings are based on 7/12 °C chilled water supply and return temperatures.

What external static pressure can this air handling unit provide?

The available external static pressure ranges from 150 Pa to 450 Pa, covering both standard and medium pressure configurations to suit different duct layouts and resistance requirements.

Is the Nano TiO2 air sterilizer included?

The Nano TiO2 healthy air sterilizer is an optional accessory. It can be integrated into this vertical air handling unit to remove bacteria, viruses, and odors. Please specify this requirement when ordering.

Can the connection direction and coil rows be customized?

Yes. We can customize the air handling unit to meet specific requirements for airflow, coil rows (4, 6, or 8 rows), and connection directions (left or right) to perfectly match your project design.
