RHeX Rotating Heat Exchanger

Rotating heat recovery unit

02

RHeX is a rotating heat exchanger specifically designed to work with dirty effluents containing mechanical particulate without losing efficiency.

Normally, heat exchangers tend to clog, foul, or lose efficiency when processing dirty fluids. By holding a constant rotation of the exchanging surfaces (the discs), RHeX can keep itself clean, thus maintaining a constant efficiency. One of the key characteristics of this design is the ability to offer a low pressure-loss in the dirty circuit, behaving as a drain channel. This avoids the need for any additional pumping thanks to the novel geometry of the rotor disks. These allow a forward pumping actions of the fluid. RHeX can efficiently recover with low maintenance when treating sewage streams or highly contaminated industrial processes. During summer, the system can be used as a higher efficiency air condition unit, and in winter, it can be combined with a heat pump to harvest energy from low enthalpy heat sources such as city sewage.
