Chiller performance and size no longer need to be at odds. The same advancements driving energy efficiency are also enabling reduced chiller footprints in both air- and water-cooled equipment.

Making specific design decisions at the project's outset can have long-lasting consequences. It's crucial to grasp these implications and effectively communicate them to the decision-makers.

Electrode boilers have existed in various forms for many decades. However, recent design improvements have closed the output gap while surpassing conventional units — not only in terms of efficiency and simplicity but also responsiveness and safety.

Whether it be basic custody transfer or demanding safety-related applications, these products always perform with accuracy. 

Since building tenants rely on the electric boilers for hot water daily, investing a little more in the initial purchase can pay off dramatically in increased long-term reliability and longevity.

Universities in the United States are increasingly eyeing electrical reliability as fires, floods, and blackouts threaten campuses.

Using technologies available in the mid-2000s, this is how Houston lowered their building NOx emissions.

Geoffrey MacDonald Halley passed away Sunday, November 19th surrounded by his children. He was 86 years old.

As the phasedown of hydrofluorocarbon (HFC) refrigerants ramps up over the next several years, technicians can expect to see a wider variety of refrigeration architectures that use lower-global warming potential (GWP) alternatives.
