High Accuracy Coolant Circulation Unit W-5030 : Hitachi High-Technologies Corporation

	The W-5030 closed water circulator is for use on scanning electron microscopes (SEMs) and atomic absorption spectrophotometers (AAs). It supplies cooling water in a closed system and saves running on cost of water.

Features

The W-5030 operates in linkage with the SEM from starting to closing. When the SEM is closed, the W-5030 closes its operation automatically after cooling the DP.
It requires no plumbing for water supply and drain.
It saves on water consumption as it operates with water in the builtin container. No extra water supply is required.
When freezing of water is anticipated, anti-freeze can be used for the cooling water.
When there is an unexpected water leak from tubing of the W-5030 and SEM (or AA), maximum volume of water is in the container. There is no continuous flow of water from the pipeline.
A new coolant of HFC-134a has been used for environmental protection purposes.
