Cree now buys chemicals and treats its systems on their own. The road to independence was at times bumpy, but in the end it proved to be an extremely rewarding journey.

Southwestern Public Service Company is unique in that through our System Engineering Department

On-line cleaning of the exchangers occurred prior to instituting the new chemical treatment program

dry and hybrid cooling systems for typical gas-fired

A method of measuring cooling tower drift loss was introduced to the Cooling Tower Institute at RM # 36

Many factors affect the operations of a recirculating cooling water system and there are numerous components that comprise the total cost of a treatment program

A number of real-world examples — from relatively simple

This specification covers the most common fills

corrective action can be initiated and repairs can be budgeted

and reduced aquatic toxicity compared to triazole compounds

Europe’s ISO-3744 and China’s GB/T 7190 are test codes which describe methods to measure sound pressure levels from water-cooling towers to compute sound power levels
