Chapter 3 – Water Supply
Adequate water cooling is critical for the reliable operation of the X-ray source. Failure to
provide suitable cooling can lead to unstable operation and severely reduced lifetime of the
source.
Caution!
Experience shows that a common reason for equipment failure is inad-
equate cooling. It is vital that you observe the information in this chapter con-
cerning the properties of the cooling water.
The following topics are particularly important for the cooling water:
Ÿ Make sure the water is clean and free of contaminants.
Ÿ Prevent biological activity in the water system.
Ÿ Ensure that the water pressure and flow rate is correct.
Ÿ
Maintain the water temperature within the correct operating range.
Ÿ Check the source frequently for signs of corrosion.
Ÿ Make sure the water current is within the accepted range for stable operation.
This chapter describes the above points in more detail. Please also refer to "Cleaning" on page
23 for details about the regular maintenance procedures. It is also necessary to clean the
source frequently to ensure the quality of the cooling water.
3.1 Quality
It is essential to use clean water for cooling:
Ÿ Do not use polluted or dyed water.
Ÿ
If there are particles in your water supply, fit a filter.
Ÿ Do not use salt water, as it will promote corrosion.
Distilled water is not advisable, as it can cause corrosion in the chiller. Its low conductivity also
means that there is a low water current, leading to unstable operation.
Clean tap water is recommended for the cooling water. If you have doubts about the quality of
your mains water supply, you should use distilled (or deionized) water and add bottled mineral
water until the water current reaches the normal range (2…10 mA).
