NEWS AND EVENTS

HVAC water treatment is critical for ensuring system efficiency, reliability, and safety by controlling corrosion, scale, and microbiological growth. Untreated water can damage equipment, reduce heat transfer, increase energy costs, and create health risks such as Legionella contamination. Effective treatment combines chemical methods—like corrosion inhibitors, scale inhibitors, biocides, and pH adjustment—with non-chemical solutions such as filtration and electromagnetic treatment. Closed-loop systems focus on corrosion and microbial control, while open-loop systems require stronger scale management. Proper water treatment can reduce energy consumption by 15–30%, extend equipment lifespan, improve indoor air quality, and ensure regulatory compliance, making it a cost-effective and sustainable investment for HVAC systems.
 

Maintaining stable water quality is essential for ensuring efficient system operation and extending equipment lifespan. Key parameters such as pH, hardness, dissolved oxygen, total dissolved solids (TDS), chlorine, turbidity, and alkalinity all play a role in influencing scaling, corrosion, and fouling. Rather than focusing on a single factor, effective water management requires continuous monitoring and balanced control of these indicators. By keeping these parameters within reasonable ranges, industrial and HVAC systems can achieve more reliable performance, lower maintenance costs, and longer service life.
 

Scaling in water systems happens when minerals like calcium and magnesium form deposits on surfaces due to hard water, high temperatures, evaporation, and unbalanced water chemistry. This leads to reduced efficiency, higher energy costs, and expensive maintenance. To prevent scaling, use water softeners, chemical inhibitors, and regular cleaning. Controlling water temperature, ensuring proper flow, and balancing water chemistry are also effective measures. Reverse osmosis can further help reduce mineral buildup. By implementing these strategies, businesses can maintain system performance, cut costs, and avoid damage from scaling.

 

# Abstract
An industrial water treatment system is a combined set of technologies and equipment that improves water quality for industrial use by removing impurities and regulating water chemistry. It mainly includes filtration, chemical dosing, water softening, reverse osmosis, degassing and pressure control components, and operates through pre-treatment, chemical treatment, advanced treatment and real-time monitoring stages. Untreated industrial water tends to cause scaling, corrosion and biological growth, while a sound treatment system boosts heat transfer efficiency, cuts energy and maintenance costs, extends equipment service life and ensures environmental compliance. Such systems are widely applied in HVAC, power generation, petrochemical, manufacturing and food & beverage industries, serving as a critical guarantee for stable and efficient industrial operation.

From March 31 to April 2, 2026, ISH China & CIHE 2026 – China International Exhibition on Heating, Ventilation, Air Conditioning, Sanitary Ware and Comfortable Home Systems, widely known as the Beijing Heating Exhibition, opened at the China International Exhibition Center (Shunyi Hall) in Beijing.

The cooling circulating water system is an open system, dust and impurities in the air and scale in the pipes will enter the water and deteriorate the water quality; more impurities will easily clog the copper tubes of the heat exchanger, reduce the heat exchange rate, and affect the effect of the entire cooling system; shallow sand filters can filter impurities in the water, reduce turbidity, reduce the blockage rate of copper tubes, and maintain the normal operation of the cooling system, so cooling circulating water systems need shallow sand filters.
