All Details About Air Booster & Air Modulator

Airflow Structure

A Tailored, controlled "need-based" airflow for the right air supply in the right volumes

Air Modulator – For efficient cold-aisle cooling

Guaranteed intelligent, energy-efficient air volume control. The Air Modulator has lowered dampers that are fitted under the floor panel and can be precisely positioned via a servo motor. This provides smart, efficient air control from your raised floor, using variable apertures to release only the amount of air actually required by the racks.

Air Booster Pro – Targeted hotspot cooling

Combats Data Center hot spots easily without major adjustments

The fins are precisely positioned to target locations that require increased cooling. This concentrated airflow goes to work on the targeted areas, reducing overall hot spot problems by also ensuring an adequate supply of cold air is still supplied to other areas.

Solutions for Airflow Units

For medium-sized and large Data Centers
Suitable for high-density racks up to 15 kW

IT sector
Easy installation, Operational in minimal time
Poorly controlled air flows will fail to cool the servers sufficiently or damage their internal fans through over supply

Air Modulator Key-Points

The unit delivers only the actual airflow required
Precise, needs-based damper control that ensures your cooling requirements are met

Suitable for use with cold-aisle containment
For installation in Data Centers with uniform pressure distribution under the raised floor
Two sensors for temperature readings

Air Booster Pro Key-Points

Conveys the required airflow efficiently from the raised floor to the server racks
Pinpoint cooling of hot sports in server racks
Easy installation, operational in minimal time

Suitable for Data Centers with raised floor
No enclosure required
Airflow of up to 2,500 m³/h
For installation in areas with insufficient air supply

Features

Controlled by temperature or pressure set point
Optional: differential pressure control prevents oversupply and minimizes air losses

Specially developed for the standard dimensions of raised floor grilles (600 x 600 mm)
Very low inrush current – can easily be powered via a UPS
Low height allows installation under raised floors (≥ 400 mm)
