For numerous reasons a closed-circuit water cooling system is the preferred option for providing cooling water to the electron microscope. Cooling water is required by the electron microscope to cool the diffusion pumps and to keep the electronics' and coiumn temperature stable.

A closed-circuit water cooling system is essential if the local water supply has a high chloride concentration, has floating particles, is acidic, has a water temperature that fluctuates and is uncontrollable. This potentially leads to specimen drift problems in the TEW, and/or has a water temperature that is very cold. This potentially leads to condensation problems or diffusion pumps not functioning properly in the TEM.
