Dedicated and driven to provide the latest innovations and technologies to the public transit industry, Nova Bus is proud to present the hePEX system. 

HePEX is a tubing system advancement designed to replace traditional copper tubes found in heating systems. It is lightweight, readily accessible, easy to maintain and resistant to corrosion. Using the hePEX system ensures a substantial life cycle cost reduction in parts and labor for transit organizations. The hePEX tubing system’s rise to eminence began over 5 years ago when first integrated into Volvo Bus Corporation vehicles.

Benefits of hePEX

The Nova Bus hePEX system is built from crosslinked polyethylene (PEX-a) tubing which includes an oxygen barrier that prevents corrosion of ferrous components in closed-loop radiant hydronic systems. The tubing features the highest degree of crosslinking for the greatest durability and flexibility.

The hePEX tubing connectors can be disassembled and tubes can be unkinked with a Pro Pex expander, without compromising the tubing’s integrity. No welding is required to install hePEX tubing, which represents significant time and maintenance cost savings for transit authorities.

American plumbing and heating contractors have valued PEX-a tubing for more than 35 years. One of the greatest benefits of this technology is its accessibility. HePEX tubes and connectors can easily be found at any plumbing store, which means parts ordering is simplified.

Finally, using the hePEX tubes contributes to decreasing overall vehicle weight as they are three times lighter than copper pipes.
