Understanding ASHRAE 188: The Legionella Risk Management Standard
Managing Legionella risk requires more than periodic testing. The ASHRAE 188 Legionella risk management standard provides a structured framework for identifying and managing conditions that may allow Legionella bacteria to grow or spread within building water systems. It establishes minimum risk management requirements for qualifying human-occupied commercial, institutional, multiunit residential, and industrial buildings, including their…
Read MoreRhode Island Legionella Regulations: A Building Water Safety Guide
Cooling towers may return to service while parts of a campus or commercial building remain lightly used. That leaves facility teams managing different operating conditions across the property, with idle equipment and low-use plumbing requiring separate attention. Understanding Rhode Island Legionella regulations starts with identifying which obligations apply to each water system. This guide connects…
Read MoreNew York Local Law 122 Cooling Tower Registration Guide
A tower replacement changes more than the equipment on the roof. Model details, system records, and assigned contacts need to match the installation before it enters service, while the maintenance plan must reflect how the new tower will operate. For owners researching “local law 122 cooling tower registration NYC,” the applicable starting point is Local…
Read MoreSalt-Based vs. Salt-Free Water Softeners: Which Should You Choose?
Hard water contains dissolved calcium and magnesium that can accumulate as scale on heat exchangers, piping, water heaters, and other commercial equipment. Over time, these hardness minerals can reduce heat transfer, restrict flow, increase maintenance requirements, and affect overall water system efficiency. When comparing a salt based vs salt free water softener, the key difference…
Read MoreWhat Is Cooling Tower Blowdown and Why It’s Necessary
Cooling towers remove heat from commercial and industrial systems by bringing circulating water into contact with ambient air. During this process, some of the water evaporates, while dissolved solids, minerals, and other contaminants remain in the cooling tower water. As evaporation continues, these substances become increasingly concentrated. Cooling tower blowdown is the controlled removal of…
Read MoreWater Quality Monitoring for Industrial Operations
Industrial water systems operate under changing conditions that can affect equipment performance, treatment effectiveness, and regulatory compliance. Variations in source water, process demand, temperature, chemical feed, seasonal conditions, and system loading can alter water quality over time. Without consistent oversight, these changes may contribute to scale formation, corrosion, fouling, microbial growth, reduced heat transfer, and…
Read MoreCooling Tower Winterization Best Practices
As temperatures drop across the Northeast, preparing a cooling tower for extended periods of cold weather becomes an essential part of facility maintenance. For commercial buildings, schools, healthcare facilities, and other sites that rely on industrial cooling towers, proper cooling tower winterization helps protect equipment from freezing conditions, minimize corrosion, and support reliable operation when…
Read MoreCooling Tower Passivation After Cleaning or Startup
Whether following routine maintenance, a major cleaning, or the start up of a new cooling tower, protecting metal surfaces is an important part of long-term water treatment planning. Freshly cleaned or newly installed galvanized steel components are more vulnerable to early corrosion until they develop a stable protective film, making cooling tower passivation an essential…
Read MoreAntiscalant Dosing Best Practices for RO Systems
Reverse osmosis (RO) systems play a critical role in producing high-quality water for commercial and industrial operations. Whether supporting manufacturing processes, food and beverage production, healthcare facilities, or large commercial buildings, these systems depend on clean, efficient membranes to maintain consistent performance. One of the most common challenges affecting RO systems is scale formation, which…
Read MoreHow to Mix Coolant for Industrial and HVAC Systems the Right Way
Heating and cooling systems in commercial buildings depend on properly prepared coolant to maintain reliable operation throughout the year. Whether protecting a closed loop HVAC system during harsh Northeastern winters or maintaining consistent heat transfer in year-round applications, understanding how to mix coolant correctly helps reduce the risk of freezing, corrosion, equipment damage, and unnecessary…
