More efficient cooling of your server racks with airflow management solutions from STULZ

STULZ airflow system solutions are employed directly in front of the server rack, under the raised floor. They utilise the same air conduction system from the air-conditioners to the racks and are controlled exactly in line with cooling requirements. Fast, simple and reliable.

                        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
