As the company who wrote the book on HVAC water treatment (literally wrote the book: Water Treatment for HVAC Water Systems) we have a unique perspective on how to best manage corrosion in boilers and hot water heaters. Several times per year, our clients from across the US will ask us about the use of […]
Updated October 28, 2024 By John Caloritis Cooling water filtration is an invaluable tool for building owners looking to maintain efficient operations and protect their water systems. Applied correctly and consistently, filtration enhances the conventional preventative maintenance (PM) chemical treatment programs. While chemical treatments control dissolved solids, microbial fouling, and corrosion, filtration targets the often-overlooked […]
Craft beer is on the rise in New York State and around the country. Many brew masters were making beer as a hobby before the craft beer trend even took off. Now they have turned a hobby from their garage into a local business in their hometown or city. So now that you have your […]
By John Caloritis Trouble Shooting a water softener begins with understanding and reacting to the symptoms found. Problems are often identified from water analyses. Water hardness is an indicator of performance, and should not exceed 1.0 ppm. Chloride or conductivity values are indicators of successful rinse protocols, and should not exceed those of the softener […]
The corrosion of galvanized steel cooling towers is commonly referred to as white rust. White rust corrosion occurs predominantly with newly installed galvanized steel towers and related cooling tower components. White rust shows up as scattered pits across galvanized surfaces, and is easily identified by a white, gelatinous or waxy deposit. If the conditions are […]
Water softening has several facets to its proper operation. One of those is proper flow for certain functions. One function of the water softener that directly relates to flow is the brining and rinsing of resin during re-generation. The Brine valve consists of a mechanical valve that opens and closes during brine-draw and refill cycles. […]
For any treatment regimen to be successful, the water quality must be monitored and maintained. This is accomplished through a series of control tests carried out to ensure consistency and to prevent the development of waterside problems. These are typically done by the facilities’ operating personnel, the WTSC (water treatment service company) or both. It […]
Technology has improved all aspects of our existence. Yes, it has even made its way into the unfamiliar terrain of water treatment. The water treatment program for most cooling towers today is supported by the use of a “controller.” These are special devices which collect input signals from either electronic probes or meters and (together […]
Under deposit corrosion in cooling systems have been one of the most prevalent problems in our industry. It is also one of the least understood problems with field level engineers and clients alike. Deposits occur in cooling systems due to colloidal sediment, environmental debris, scale, old corrosion deposits re-depositing on metal surfaces and of course […]
Closed Loop Systems Treated With Glycol A variety of heat transfer fluids are used to provide freeze protection for industrial equipment and HVAC closed-loop heating and cooling systems. These fluids may be used in systems that operate anywhere between -60°F to 300°F. Many heat transfer fluids are glycol-based, containing either ethylene glycol or propylene glycol. […]
