Tube bundles are an essential part of the HVAC and hydronic system of a commercial facility. They are the heating elements that exchange and transfer energy in the form of heat into the water that is then typically used for either building heat or domestic hot water requirements. Without this critical component, the system wouldn’t work at all—which is why it’s such a big problem if it fails.

It’s important to make sure that your tube bundles are in good working condition if you want to keep the system functioning at optimal levels. If the HVAC tube bundle ruptures or springs a leak, hard water may enter your condensate return system and damage your boiler, or steam could migrate into your hydronic system and create a dangerous environment to the domestic and/or heating systems. Here are a few things to look for if you’re unsure about how to check your tube bundles for damage.
