HRN Water-Saving Anti-Plume Industrial Cooling TowerIndustrial Water-Saving & Anti-Plume
An industrial cooling tower where wet-section cooling and plume-abatement heat exchange work together for high-load heat dissipation.
The HRN series is a water-saving plume-abatement industrial cooling tower built by LANXUN for heavy-industry high-load conditions. It coordinates the wet-section cooling with a plume-abatement heat exchange section (GS/LN/GSLN three options), effectively suppressing plume discharge while ensuring an extra-large cooling-water flow of 1200–6000m³/h. Three tower-body forms are offered — steel structure, concrete structure, and FRP — to suit different project budgets and construction conditions. The core fill uses S-wave modified PVC material with a large specific surface area, B1 flame-retardant, and a 20-year service life. Widely used in petrochemical, steel, and power industries, the HRN series is the main force in industrial water-saving and plume abatement.
Key Highlights
Three Plume-Abatement Modes (GS/LN/GSLN)
Three plume-abatement solutions are offered — GS dry path, LN low-noise dry path, and GSLN combined — selected flexibly by fog level and economy.
High Load (1200–6000m³/h)
A single tower covers 1200–6000m³/h of extra-large cooling-water flow; multi-tower parallel expansion reaches tens of thousands of m³/h for million-ton industrial water needs.
Three Tower-Body Structures
Steel (economical), concrete (durable 50+ years), and FRP (best corrosion resistance), selected flexibly by project and budget.
S-Wave Modified PVC Fill
B1 flame-retardant, specific surface area >150m²/m³, with UV stabilizer added for aging resistance and a design service life of ≥20 years.
Working Principle and Structural Features
The following content is excerpted from the HRN Water-Saving Anti-Plume Industrial Cooling Tower product manual
Working Principle
The HRN series counter-flow cooling tower is available in three forms by tower body material—steel structure, reinforced concrete structure, and all-FRP—with design conditions of: inlet water temperature 43℃, outlet water temperature 33℃, wet-bulb temperature 28℃, dry-bulb temperature 31.5℃, atmospheric pressure 9.94×10⁴Pa.
Hot water is evenly distributed at low pressure by three-splash nozzles, requiring only 0.6mH₂O to reach even water distribution pressure and reducing head loss; after the water leaves the splash pan it forms three layers of water flow, creating a three-dimensional droplet group of varying height and distance that spreads the hot water evenly over the top of the fill without voids, increasing water-air heat exchange and improving cooling efficiency.
The airflow through the tower's sprinkling section is organized by the flow-contracting section of the elliptically designed fan stack and uniformly transitions to the fan working section; in the fan working section the airflow does work through the blades and is raised to the dynamic-pressure recovery section, where a dynamic-pressure recovery section designed on gas-flow-field homogenization theory guides and diffuses the airflow, effectively reducing the dynamic-pressure loss of the airflow in the exhaust stack.
Motor Dedicated to Cooling Towers
A Y2 series high-efficiency horizontal asynchronous motor dedicated to cooling towers, compliant with IEC standards; outdoor type with IP55 protection and Class F insulation, fitted with premium wear-resistant bearings, with an effective motor life of more than 15 years.
Right-Angle Gear Reducer
A right-angle high-power industrial reduction gear unit with oil-immersed positive-lubrication reduction gears; SKF imported bearings are optional, and the coupling shaft is a premium 304L stainless steel drive shaft, or an imported carbon-fiber shaft can be fitted.
Low-Noise Axial Fan
A new axial low-noise fan dedicated to cooling towers, molded from high-strength epoxy FRP, applying aerodynamic principles and an airfoil-profile design, with large air volume, high efficiency, smooth operation, and interchangeable blades.
S-Wave Modified PVC Fill
Uses brand-new S-wave modified PVC fill with an original counter-flow tower hanging fill system for easy cleaning and maintenance; the fill has an oxygen index of up to 46.1%, meets China's Class B1 flame-retardant grade, and has a normal service life of 20 years.
Three-Splash Nozzle
Low supply pressure—only 0.6mH₂O is needed to reach even water distribution pressure; the water distribution forms a three-dimensional droplet group of three water-flow layers spread over the top of the fill without voids; the nozzles are fixed with ABS/stainless steel bolts to prevent them from falling off.
High-Efficiency Drift Eliminator
Uses a sine-wave JT-45 modified PVC reinforced drift eliminator with machine-formed sheet thickness ≥0.8mm and ABS supports; drift loss is no more than one part in 100,000, the flame-retardant oxygen index is greater than 40, and the service life is at least 15 years.
