Water-saving & Plume Abatement Technology
Winter water-saving rate 85%+, dual-path anti-plume, balancing both environmental protection and energy saving
Winter Water-saving Rate 85%+, Dual-Path Anti-Plume
The LANXUN water-saving & plume abatement cooling tower adopts an innovative combined dry-wet dual-path design that effectively eliminates visible plume while ensuring cooling performance. In winter the dry channel is engaged, with a built-in condensing module recovering condensate, achieving a water-saving rate above 85%; in summer it switches to full-wet mode to ensure cooling efficiency. This technology has obtained 17 related patents and is widely used in urban rail transit, commercial complexes, and noise-sensitive areas.
How Dual-Path Anti-Plume Works
Four steps to understand the core principle of the dual-path anti-plume water-saving & plume abatement technology
Schematic of the dual-path anti-plume water-saving & plume abatement working principle
Industry Background
Conventional cooling towers generate large amounts of white plume in winter, affecting the surrounding environment and traffic safety while wasting significant water resources. LANXUN pioneered the dual-path anti-plume water-saving and plume abatement technology, achieving a dual breakthrough in both water saving and plume abatement for cooling towers.
Dual-Path Anti-Plume Principle
A parallel design of dry and wet channels: the wet channel handles the main heat exchange task, while the dry channel introduces external cold air to reheat the humid hot air, lowering relative humidity so that the exhaust air dew point is below the ambient temperature, fundamentally eliminating plume formation.
Open/Closed Switching
In winter the dry channel is engaged for water saving and plume abatement; in summer it switches to full-wet mode to maximize cooling efficiency. The intelligent control system automatically adjusts channel switching based on changes in ambient temperature, humidity, and load.
Condensing Module & Quantified Water Savings
A built-in high-efficiency condensing module condenses and recovers the water vapor in the humid hot air. The winter water-saving rate reaches over 85%, with an annual comprehensive water-saving rate of 50%~70%; quantified water-saving data can be viewed in real time via the cloud platform.
