Roof-Top Heat Exchanger System

Recapturing waste heat to save energy is a complicated process that can lead to processing downtime. Heat exchanger downtime due to breakdowns, service or maintenance can be expensive due to lost revenue. Energy savings can pale in comparison to lost profits. What was meant to be an environmentally responsible solution can turn into a financial nightmare.


The ENERVEX RHX Heat Exchanger System is a cutting-edge, turnkey solution for capturing and recycling excess heat from most processes, turning it into valuable energy savings and reducing CO2 emissions. It eliminates all the concerns about downtime and provides real savings.

  • Production downtime can be less than 30 min during a roof-top installation!
  • The RHX is a turnkey solution with integrated heat exchangers, plumbing, circulation pump, dampers, mechanical exhaust and controls. All that’s needed are utilities - supply and return pipes and power
  • Quick and straightforward installation – cut the chimney back and place the RHX on top
  • An integrated damper can bypass the heat exchanger and allow free-flow exhaust during service & maintenance.
  • The RHX will never cause process downtime


The RHX is a skid-mounted turnkey heat recovery unit with unique features and designed to fit individual needs.
