For example, a cryopump will pump water vapor much faster than an equivalently sized turbomolecular pump, but both pumps might have exactly the same speed when pumping nitrogen. High vacuum pumps may ...

For example, a cryopump will have a much higher water vapor pumping speed than a turbomolecular pump, even though both pumps might have exactly the same nitrogen speed. Mechanical vacuum pumps may ...

In the 1980's both SHI and APD launched higher capacity 10K coolers for the cryopump market in Japan and for diagnostic imaging systems in Europe. In 1993, the engineering team at APD developed ...
