Information processing and uptime are critical to the functioning of today’s businesses; wherein business-critical technological rooms have unique environmental requirements and, namely, necessitate cooling devices that can match these requirements. Technology rooms produce an unusual, concentrated heat load, and also, are very sensitive to changes in temperature and humidity. For such equipment rooms, temperature and/or humidity swing can produce many problems including a complete system shutdown. Eventually, depending on the length of the interruption and the value of time and data lost, can have huge costs for the organization. Standard comfort air conditioning is not designed to handle the heat load profile of critical purpose areas, nor it is designed to provide the precise temperature and humidity set point required for these applications. Precision air conditioning systems are designed for close temperature and humidity control. They provide high reliability for year-round operation, with the ease of service, system flexibility, and redundancy necessary to keep critical applications running 24 hours a day.
A summarized table narrate the situation as hereunder:

Thus evidently, Precision cooling has become an integral part of mission-critical facilities of Datacenter and telecom segment. Nevertheless, room cooling solution is increasingly being considered for this application but also, there is a host of other applications where such sensitive electronics are increasingly deployed. Among them, the industrial application is one of those treasure quarters.
Being an architect of continuity, Vertiv always prioritizes technology support for round-the-clock business operation and come up with inventions that support uninterruptible operations in critical applications. Liebert Data Mate (Liebert DM) is a room cooling unit suitable for the sensible heat-load-based application. It is a solution for higher Sensible Heat Ratio (SHR - 0.9) based dry heat load, which is mainly generated by critical equipment. With further improvement in technical features, it is now available in the DX version with 7 kW, 12 kW, 17 kW, 22 kW, and 27 kW options. Liebert DM is getting best fitted among small room cooling applications because of its high SHR, higher efficiency, and very small footprint.
Liebert DM supports all typical IT & small Industrial applications namely- small server room, control room hub room, or computer room comprising of 2-5 racks with a capacity of 1 kW/rack to 3 kW/rack. Such application is widely deployed in Banks, Healthcare, Government Institutes, Energy Sector, and Transportation Segments. Over and above, Liebert DM is also suitable for UPS & Battery room- which is essentially established as a power backup solution for the above-stated business segments.
Some of the segments mentioned above still use comfort cooling equipment-based solution that compromises the cooling needs and becomes a costly affair. Statically, in a 10~12kW equipment heat load application approximately $4.3K electricity bill (considering $0.15/kWh) can be saved by using Liebert DM solution over a standard comfort air conditioning system.
Further, Liebert DM is available in a downflow, up-flow front configuration. Energy-efficient refrigerants i.e. R410A & efficient scroll compressors are standard offerings with Liebert DM. It also offers a remote monitoring system and various other features that create reliable & efficient room cooling solutions for the small technological room.
Recently Vertiv has announced the availability of the Liebert DM full series in Australia and New Zealand and Southeast Asian countries. To learn more, click here.
