UVI Series Vertical Unit Heater

The UVI unit heater is designed to heat buildings with high ceilings. It may also be used to re-circulate warm air that builds up near ceilings. UVI heaters can be used as primary, supplemental or dual heating systems in commercial or industrial buildings.

  • Vertical Airflow: Suitable for applications in high bay industrial buildings where columns, machinery or warehouse stock would obstruct horizontal air movement.

  • Air Distribution Patterns: Three optional air diffusers produce different air distribution patterns to accommodate various applications.
