Luba GL

Luba GL is a lightweight rooftop solar hot air collector for supplemental outside air heating in commercial, institutional and industrial facilities. Luba GL technology boasts a maximum thermal output of 247-BTU/h/ft2 (780-watts/m2) and airflow of 6 to 12-cfm per 112 (L) x 36 (H) x 8 (D)-inch collector. It features a lightweight twin-wall, 1/4-inch-thick (10-mm) polycarbonate glazing and 26.4-square-foot (2.5-square meter) black aluminum backpanel. The patented Luba GL's backpanel perforations transpire air from outside to within the collector from the backside, which reduces heat loss and eliminates the weight and cost of insulation used in other collectors.
