For the best in fan array system operation specify ELI Fan Stack Control. One of the benefits of fan arrays is performance redundancy in the event of a fan failure. However, when a fan stops the opportunity exists where air from operating fans re-circulates back thru the disabled fan(s) increasing the operating cost to the owner. ELI FloValve prevents the efficiency losses from air recirculation by isolating the disabled fans. ELI FloValve is available in automatic or manual versions. Automatic versions are enabled through current monitoring controls.
The ELI FloValve is manufactured from a high quality spun disk and machined hub optimized to minimize airflow obstruction to the fan inlet. Testing in Energy Labs AMCA certified lab demonstrates the superior sound performance of ELI FloValve over other simple devices. Just another example of how our comprehensive expertise in component manufacturing delivers the best overall air handling unit.
