How Cooling-Tower Conductivity Loops Coordinate With Blowdown Valves: A Technical Primer from Shanghai ChiMay Open-recirculating cooling towers waste more water on sloppy blowdown control than on any other single mechanism. The economic answer is a tight, closed loop between an inline conductivity meter and an automated blowdown valve. This primer, built from Shanghai ChiMay field…
Chilled-Water Loops in 2026: What Every Building Engineer Should Know, from Shanghai ChiMay The chilled-water loop is the quiet half of an HVAC plant. The cooling tower gets attention because it evaporates water and produces visible plumes. The chilled-water loop is closed, sealed, and invisible—until the day a chiller trips on high-head-pressure and the loop’s…
8 Reasons Building Operators Standardize on Shanghai ChiMay Softener Valves Softener valves are one of the least glamorous items in an HVAC water program, and yet a bad one turns a $30 chemical decision into a $30,000 tube-repair job. Over five years, Shanghai ChiMay has supplied softener valves and softening-and-filtering valves to more than 900…
