Author: K. Anthony Selby; Arthur J. FreedmanAn active building has many service water systems in use for HVAC purposes and many different materials in those system a for “corrosion-free” containment. All
Author: Richard A. Hoffmann; Arthur J. FreedmanThe presence of deposits in pipes and equipment, or the appearance of leaks, is the driving force for considering a cleaning program. The choice between
Author: R. Hoffmann, A. FreedmanHigh cycle cooling water operations are typically practiced in water short areas and in areas where extreme environmental sensitivity exists. The resulting open, evaporative cooling
Author: Arthur J. Freedman; Thomas M. Laronge; Chester M. Malewski; Craig W. WilliamsThe cleaning of HVAC and industrial cooling systems is a complex process that requires careful planning. The presence of large quantities of deposits in pipes
