New intervene film technology:utilize copper,aluminum and titanium three target film technology.
High heat efficiency:12% higher than common vacuum pipe Anti aging and attenuation:common vacuum pipe will be aged and attenuated in high temperature and shining condition (250).Three target vacuum pipe can bear 400,the life of the pipe is extended greatly.
