Ozone Aging Test Chamber
The Ozone Aging Test Chamber LEOZT exposes rubber specimens under static tensile deformation, such as vulcanized rubber, thermoplastic rubber and cable insulation sleeves, to a constant ozone concentration and temperature in a sealed, dark chamber for a set time. The specimen surface is then examined for cracks and other property changes to rate its resistance to ozone aging.
How it works
A silent discharge ozone generator feeds the working room and an ozone analyzer measures concentration, which is held within ±10 percent. Ranges offered are 0 to 1000 pphm, a high range of 25000 to 30000 pphm, or 5 to 300 ppm. An air duct interlayer on three walls carries a stainless steel heater, a surface evaporation humidifier and circulating fans; balance exhaust holes on top keep the chamber concentration steady. Temperature runs from room temperature to +80 °C and humidity from 45 to 98 %RH, with fluctuation of ±0.2 °C and ±0.5 %RH. A refrigeration circuit provides cooling and dew point dehumidification. Control is by digital indicators with PID computation and solid state relays. Specimens sit on a rotating aluminum alloy table turning at 1 r/min.
Six sizes are offered, LEOZT-080 to LEOZT-1000, with working rooms of 80, 150, 225, 408, 800 and 1000 L and connected power of 4 to 11.5 kW. The inner chamber is SUS 304 stainless steel, the exterior is powder coated stainless plate, and insulation is PU and fiberglass wool.
