SEFH Fluid Heated or Cooled Louvers

SEFH will melt snow and ice on high-efficiency coil-style fluid-heated vertical louvers while also heating the air. A typical air temperature rise of 15 to 30F is possible. SEFH is also a vertical-style louver capable of removing large quantities of rain and fog from the air stream.

Snow bounces off and through most cold louvers, hoods, and drift eliminators until it finally builds up on the filters or on the eliminator. Veotec SEFH fluid heated louvers melt snow and prevent icing. Snowflakes instantly melt into water droplets where we effectively drain the coalesced droplets away. SEFH fluid heated louvers are optimally spaced for first stage water removal for inlets and filtration systems so there is no need for pre-filtration like normal coils. In many cases these louvers can be bolted in place of hoods. If required, the louvers can be sized to fit inside of most hoods. Inlets already using coils can benefit from an added boost in performance.
