Over the years, spiral ductwork has become increasingly popular thanks to its bevy of benefits. At this point, it has eclipsed rectangular ductwork as the industry standard for commercial HVAC systems. Let’s take a look at some of the useful properties that make spiral duct so sought after for HVAC applications.

Low Leakage

Air leakage is a big problem in commercial HVAC systems. It is often directly linked to sub-par system efficiency, higher operating costs, and poor indoor air quality. Spiral ductwork has a much lower leakage rate than rectangular ductwork, because it has fewer joints (which are common leakage sites).

High Efficiency

Efficiency is one of the most important elements of any industrial ventilation system. Spiral ductwork is more efficient than rectangular ductwork for a couple of reasons. For one thing, as previously mentioned, spiral duct leaks less than rectangular duct. For another, spiral ductwork allows for better airflow, because it has fewer sharp angles and internal seams to slow air as it travels through the system. The smooth, round interior of a spiral ductwork system creates a constant internal pressure that allows for efficient airflow throughout the entire HVAC system.

Low Cost

Cost is always a serious consideration when acquiring a commercial HVAC system. This is yet another category in which spiral ductwork outperforms rectangular ductwork. Spiral duct is significantly lighter than rectangular duct. As a result, it is cheaper to transport and more affordable to install. Additionally, spiral ductwork’s superior efficiency results in lower HVAC system operating costs over time.
