UV UV photolysis purification system, the UV lamp will produce 254nm and 185nm two wavelengths, with 254nm dedicated UV lamp to cut the grease molecule chain, forming small grease molecules, while 185nm ultraviolet light and air oxygen reaction after producing ozone, ozone will small grease molecules "cold burning" producing water and carbon dioxide and trace white powder, organic matter in oil smoke is photolysed oxidation, and the odor in smoke duct will also be significantly reduced.

II. Teknoloji
UV-C ultraviolet C band (254nm) rays radiating small particles of oil (protein molecules composed of amino acids, fat molecules composed of fatty acids, etc.) cut the oil molecule chain, changing the molecular structure of oil, oil and volatile organic matter are vulnerable to UV-C.

Oxygen molecules that break air using high energy high ozone UV-C ultraviolet rays produce free oxygen, i.e. active oxygen, because free oxygen carries positive and negative electrons imbalance so need to be bound with oxygen molecules, thus producing (Ozone 03).
