The V-SIO configurations on this page represent only our most popular designs.  Utilizing Energy Recovery Wheels, Heat Pipes and Enthalpy or Sensible plate exchangers.

Heat Pipe Technology

HRM heat pipes provide efficient heating and cooling energy recovery with no moving parts, delivering long service life and minimal maintenance. Designed for side‑by‑side or over‑under airstreams, they prevent cross‑contamination, making them ideal for labs, hospitals, and other critical facilities. Their loop‑circuit design enables bi‑directional heat transfer without seasonal changeover, offering economical, dependable performance.

Nortek

Nortek’s Energy Recovery Systems capture energy from exhaust air to pre‑heat or pre‑cool incoming outdoor air, delivering significant energy savings and improved indoor air quality. With AHRI 1060‑certified wheels, plates, and heat pipes, plus options like FANWALL® fans, advanced controls, waterside economizers, and filtration up to MERV 17, these systems are ideal for 100% outdoor air applications requiring maximum efficiency and humidity control.

NovelAire

NovelAire’s Energy Conservation Wheels deliver industry‑leading sensible and latent energy recovery, reducing HVAC loads and enabling smaller, more efficient system designs. With AHRI Standard 1060‑certified performance, rugged construction, and capacities up to 50,000 CFM, these wheels provide reliable ventilation energy savings for commercial, educational, and healthcare applications—while preventing cross‑contamination with their sealed, homogeneous desiccant media.
