Data Center Cooling: The Thermal Backbone of Digital Infrastructure

This mission-critical infrastructure requires coordinated control of heat load, airflow, humidity, cleanliness, redundancy and energy efficiency to keep increasingly dense digital systems reliable and scalable.

As digital infrastructure becomes more powerful, more compact and more essential to everyday business operations, data center cooling has become one of the most important disciplines in facility engineering.

The Role of Cooling Towers and Importance of Water Conservation

Cooling towers are highly efficient heat rejection systems; however, they can consume a lot of water. Pairing cooling towers with heat recovery, geothermal systems and integrated building planning can reduce energy, save water, and turn waste heat into a valuable resource.

Cooling towers play a critical role in heat rejection for power generation, industrial and lab process cooling, data centers and, more commonly, in HVAC cooling systems.

Hot Water for Process: Stop Using Steam to Make Hot Water

Industrial facilities can improve efficiency, sustainability, productivity and compliance by replacing steam-based hot water generation with direct, right-sized hot water systems while retaining steam where it remains necessary.

Steam built the industrial age, but it doesn’t have to run it any longer. In fact, in many cases, it shouldn’t.

Clearing the Confusion: The Truth about CMT

Approved for use in medical gas systems, the corrugated copper tubing performs just like rigid copper but installs in a fraction of the time while increasing site safety.

Although corrugated medical tubing (CMT) is often perceived as a relatively recent solution for medical gas systems, it has been proven in the field across industries for more than 20 years.

Supreme Court Lowers Initial Filing Hurdle for Suits Against Design Professionals

Federal courts are barred from applying state affidavit-of-merit requirements at filing, lowering the threshold for malpractice claims against design professionals while shifting early litigation strategy in diversity cases governed by the Federal Rules of Civil Procedure.
Steven Nudelman

Earlier this year, the U.S. Supreme Court issued a decision in a Delaware medical malpractice action with particularly important ramifications for all professional malpractice actions brought in federal court.

The Fire Hazard of the Modern Vehicle

Increased use of plastics, larger vehicles, denser layouts and automated parking can make fires harder to control and more damaging once they start.

When we consider all that’s changed in the transportation world over the last decade, the electric vehicle (EV) boom takes center stage.

The History of Backflow Prevention and Plumbing Codes, Part 3

Double check valve assemblies, detector check valves and reduced-pressure zone assemblies protect potable water systems from backflow, especially in fire protection and high-hazard applications.
Ron George

Last month, in Part 2 of this series, we covered air gaps, air breaks, atmospheric vacuum breakers, hose thread applied vacuum breakers and pressure vacuum breakers.
