Think Twice Before Specifying a Comfort RTU for Your Data Center

Building and operating a data center requires maintaining compliance with increasingly complex requirements, and not specifying the right equipment can be a costly mistake for everyone involved. Improperly sized or rated HVAC systems can delay schedules, increase maintenance costs, or lead to failures that can cost millions of dollars per hour in an industry that requires continuous uptime.

At STULZ, we see this problem every day. Our company specializes in listening to customers and delivering purpose built solutions for mission critical environmental control. This includes air conditioners, air handlers, humidity control, and custom solutions.

Consider a recent customer; a major telecommunications provider who made a significant investment in packaged rooftop air handlers to cool their data center. The RTUs specified were commonly used in commercial construction. Unfortunately, within months it was clear that these units were unable to successfully withstand the rigors of 24×7 operation, and the high return temperatures which are becoming common in data centers due to mandated improvements in energy efficiency.

By working with STULZ, the customer was able to replace the failing RTUs with the CyberPack Packaged Rooftop System which was specifically designed for this type of application and purposefully built to use the same mounting dimensions as the failing systems. No serious modification to the building infrastructure was required and for more than a year, these CyberPack units have been serving the customer’s need as they continue to build and expand.

Comfort cooling HVAC systems may be a good value for commercial use, but when it comes to data centers, not having the appropriate solution can be a devastating mistake. STULZ experts are ready to help you find your data center solution.

Why Humidify Your Data Center or Mission Critical Facility?

Whether you’re a seasoned data center professional or new to the industry, you probably know that humidifying your data center plays a vital role in the longevity of your space.  Today’s data center environments require meticulous control of humidity to eliminate static electricity, ensure quality manufacturing processes, preserve precious documents and works of art, and provide comfort while adhering to Indoor Air Quality standards. The specific reasons to use humidifiers to add moisture are as numerous as the applications, but the purpose is common across the board: to eliminate problems that can damage products, ruin buildings, or jeopardize health.

When RH reaches levels below 35%, static electricity may develop on surfaces and materials. Static electricity is not only annoying; it can wreak havoc on computers by burning microchips, and wiping out memory cards. Elimination of static electricity also greatly reduces the risk of solvent fires in the printing industry – commercial presses develop extraordinary amounts of electricity at the roller and ignite solvents in the ink wells. And if you ever wiped your finger across your television screen you know that static electricity attracts dust, a real problem in the plastics and films manufacturing process where dust can ruin a product or in the health care industry where dust can kill. Indoor Air Quality affects man and machine and both operate best at optimum environmental conditions. IAQ and IEC standards are forcing manufacturers and building owners to adjust their management of air quality control. If a building’s main HVAC system does not have the capacity to maintain RH levels within a comfort zone of 50% to 60%, then proper humidification can help reduce adverse effects of occupant discomfort, bacteria growth, viruses, fungi, mites, allergic reactions, respiratory infections, chemical interactions and ozone production.
