This three-stage sand-proof & thermal insulation adjustable louver is primarily applicable to power plant turbine halls, boiler rooms, control buildings and other facilities in cold desert regions requiring ventilation and thermal insulation.
It is composed of vertical sand-retaining blades, inner adjustable (closable) blades, a frame with sand and water drainage functions, and electric actuators. Single-layer casement windows made of UPVC or aluminum alloy are fitted on the inner side to provide indoor thermal insulation. It delivers an optimal solution for sand prevention, rain protection, airflow regulation and thermal insulation for such cold desert zones.
