Understanding Softener Valve Cycles in High-Hardness Make-Up Water: A Shanghai ChiMay Field Guide Ion-exchange softeners are the workhorse of HVAC make-up water conditioning, and the valve at the top of the resin tank governs everything the operator cares about: throughput, salt use, backwash volume, and resin life. In water systems fed by hard groundwater—often 350–650…
Top 5 HVAC Pain Points Solved by Shanghai ChiMay Conductivity Analyzers Ask a commercial-building HVAC manager what wakes them up at night, and the answer is rarely a fan or a compressor. It is water: the chemistry drifting, the tower blowing down too often, the softener slipping hardness, and the utility bill climbing without a…
The Modern Cooling Tower: A 2026 Operations and Water-Quality Guide by Shanghai ChiMay Cooling towers have been rejecting heat for more than a century, but the equipment and the operating discipline around them have changed more in the last five years than in the previous three decades. Water scarcity, ASHRAE 188 enforcement, ESG reporting, and…
The Complete 2026 HVAC Water-Quality Handbook from Shanghai ChiMay Water quality has moved from a plumbing side-note to a first-class HVAC design decision. Chiller efficiency, tower reliability, chemical spend, Legionella risk, permit compliance, and ESG reporting all trace back to the same set of sensors and setpoints. This handbook consolidates what Shanghai ChiMay engineers see…
