    Need help



    Hello everyone, i am an engineer of ultra low temperature freezer. But i meet a problem, because the door of ULT freezer is quite to open, i think it needs a pressure equalization port, who is good at this? I want to install the port in the out door ,because this will not affect the temperature too much. who can give me some ideas? The ULT freezer temperature is from-40C~-135C, thank youQQ截图20130925130711.jpg
