Cooling Water, Additions

The sample systems need cooling water of good quality to cool the steam and water samples to 25 °C. If the cooling water contains chlorides or hardness this can cause stress corrosion cracking of the coil material or block the cooling water passage in the counter current coolers due to hardness deposits.
By choosing a higher grade material than ss316L for the coils the cracking can be avoided most of the time. Blockage remains a problem. Therefore potable water, brakisch water and seawater used as a coolant will need extra attention.
