Our Foundation

The word nexus means a connection or series of connections within a particular situation or system. The founders of Nexus used this fundamental meaning to create a unique brand and be one of the earliest innovators of specialized hydronic components and packaging.

Established in 1994, Nexus set forth to build balancing and control products that are highly configurable and capable of reducing installation time by 77%. Innovative products like the Nexus Coil Paks provide fewer potential leak points, save up to 50% in space, eliminate field engineering or errors, and have cleaner installations.

Nexus continues to be an industry leader in creating hydronic balancing and control solutions, providing contractors with quality and flexibility. With every connection made, we continue to provide single sourcing of quality hydronic components at an affordable cost while also providing value-added services for resellers and users of hydronic products.

Our Mission

Help our customers win with innovative hydronic solutions that improve system performance, save energy, and optimize installation.
