Item No.:
SJL-VT
Description:
All glass evacuated tubes are the key companent of solar collectors. The evacuated tube is similar to a conventionak dewar flaskk and consists of two borosilicate glass tube, a glass with high chemical and thermal shock resistance. The inner tube is coated with a sputtered solar selective surface. This coated inner tube is closed at one end and sealed at the other end to the outer tube. The annular space between the outer tube and inner tube is evacuated to virtually eliminated heat loss by conduction and convection.
