Cryogenic equipment for roller

Cryogenic equipment for roller Material: AISI 304 stainless steel size and demension:Dia1800*8000mm control: touch screen and PLC control working temprature:+200°C to -196°C accuracy:±1 °C Cryogenic (Beijing) Science & Technology Co.,Ltd is a leading manufacture ofliquid nitrogen system andcryogenic equipment in China.Using liquid nitrogen (-196°C) as coolingmedium,making a rapid speed of cooling and frozen. DC-8000 is designed for the large roller. using liquid nitrogen as the medium,creat a environment of low temperature, making the roller get better performance: improve the hardness 1 to 2 degree the wear resistance will be enhanced improve the service life about 4 times Kindly contact me for more details
