A glycol chiller is a refrigeration system that cools a glycol-water mixture and circulates it through a closed loop to hold precise temperatures in commercial building HVAC systems and industrial processes. Because the glycol solution resists freezing, these systems can run at temperatures plain water cannot, protecting piping and equipment through winter conditions and low-temperature applications. Understanding […]
Heat Pump Maintenance and Water Treatment for Hydronic Systems
As heat pump technology becomes more common in commercial buildings, facility managers and building engineers are discovering the importance of comprehensive heat pump maintenance programs. While many heat pump maintenance guides focus on refrigerant levels and outdoor unit care, hydronic heat pump systems need attention to an additional critical component. The water circulating through the […]
New NYC Legionella Testing Requirements Starting In 2026
If you manage a building with a cooling tower in New York City, you need to understand the compliance changes coming in 2026. Local Law 159 of 2025, passed by the City Council in October 2025, changes legionella testing from quarterly to monthly for all cooling towers in the five boroughs, significantly impacting maintenance schedules and […]
Boiler Blowdown Basics and Differences Between Manual and Automatic Controls
The difference between a boiler system that runs efficiently for decades and one that breaks down every few years usually comes down to understanding proper boiler blowdown management. Every facility with a boiler system needs to understand boiler blowdown because it directly impacts equipment life, energy costs, and system reliability. When water turns to steam, […]
Protecting Cooling Tower Chemical Feed Systems During Winter Using Heated Enclosure
Facility managers operating cooling tower chemical feed systems in Northeast climates face a critical infrastructure decision each winter. When cooling tower chemical feed systems must remain operational during freezing conditions, the choice between proper protection and cost-cutting measures determines whether you maintain reliable chemical programs or face expensive emergency repairs and system shutdowns. This comprehensive […]
Steam Boiler Treatment Solutions That Extend Equipment Life
Steam boilers are integral to the infrastructure of many commercial and industrial buildings, particularly in the Northeast. They are commonly found in high-rises, hospitals, schools, and manufacturing facilities where high-capacity heating or process steam is required. While these systems can last several decades in service and are effective when properly maintained, they are frequently excluded […]
