Closed Circuit Cooling Towers for High Heat & Humidity | Liuchu Refrigeration

Release Date: July 23, 2026

Location: Zibo, Shandong

As the Northern Hemisphere enters the mid-summer "Three Dog Days" in late July, global manufacturing faces severe challenges in industrial equipment heat dissipation. In Southeast Asia and China's coastal areas in particular, high temperatures, intense humidity, and high salt spray environments present massive operational trials for traditional industrial cooling systems.

Following the successful delivery of four large-tonnage closed circuit cooling towers (three 250T units and one 180T unit) to the Philippines this week, the Liuchu technical team has summarized two core breakthrough solutions targeting the cooling pain points of hot and humid working conditions:

I. Rejecting Single-Temperature Comparisons: Precision Calculation Based on "Wet-Bulb Temperature"

In tropical and humid regions like Southeast Asia, high air humidity severely impairs evaporative cooling efficiency. Designing cooling towers based solely on standard dry-bulb temperatures frequently leads to summer water temperature spikes, forcing production line throttling or shutdowns.

During the preliminary design phase, the Liuchu engineering team performs computational fluid dynamics (CFD) and thermodynamic simulations based on historical peak wet-bulb temperatures (Wet-Bulb Temperature) from local meteorological stations. By precisely calculating the heat exchange coil surface area and airflow distribution, Liuchu ensures that even under extreme "sultry tropical weather," outlet water temperatures remain strictly and stably within process requirements.

II. Abandoning Aging-Prone Materials: ZAM Steel Sheets and 304 Stainless Steel Build a Robust Anti-Corrosion Shield

High-temperature and high-humidity environments accelerate the aging and corrosion of ordinary carbon steel plates and traditional Fiber-Reinforced Plastic (FRP). Liuchu closed circuit cooling towers come standard with premium Zinc-Aluminum-Magnesium (ZAM) coated steel sheets, with high-end customized 304/316 stainless steel options available:

• Self-Healing Cut Edges & Superior Corrosion Resistance: The ZAM coating possesses remarkable cut-edge self-healing capability and salt-spray resistance, delivering anti-corrosion performance multiple times greater than standard galvanized steel.

• All-Metal Non-Combustible & Long-Lasting Durability: Completely eliminates safety hazards associated with FRP—such as embrittlement, cracking, and flammability—substantially extending the full lifecycle of the equipment.

Sean, Manager of the Export Department, stated: "Clients in Southeast Asia and coastal areas repeatedly choose Liuchu precisely because they value our technical rigour in all-steel construction and wet-bulb temperature engineering. Whether tackling complex tropical climates or meeting peak summer cooling demands across various domestic industries, the Liuchu team speaks with data to tailor the most energy-efficient and durable closed-loop refrigeration systems."
