Product Overview
The Crossflow Open Cooling Tower from HACST Cooling is engineered for high-performance evaporative cooling in demanding industrial and commercial environments. Featuring a streamlined crossflow design, this tower provides energy-efficient cooling with exceptional maintenance accessibility, lower noise levels, and scalable modularity for future expansion.
Key Features & Advantages
- Gravity-Fed Water Distribution – Simplified design eliminates pressurized nozzles, reducing pump energy consumption and enhancing reliability.
- Superior Accessibility & Low Maintenance – Open-side design enables easy inspection and cleaning of internals, significantly reducing downtime.
- Low Operational Noise – Minimal falling water noise and fan placement contribute to quieter functionality.
- Cost-Effective and Energy Efficient – Lower fan power requirements and gravity-based water flow offer long-term operational savings.
- Resilient in Cold Climates – Less prone to freezing compared to counterflow towers, making it ideal for climates with low ambient temperatures.
- Scalable & Modular Design – Easily expanded to accommodate growing heat rejection requirements.
Working Principle
Hot water is evenly distributed from the top basin by gravity over the fill media. Simultaneously, ambient air enters horizontally through the side louvers and passes across the water stream, promoting evaporation and effective heat transfer. Cooled water collects in the basin for recirculation.

Applications
Ideal for:
- HVAC systems in commercial buildings
- Chemical & Petrochemical cooling processes
- Food & Beverage production lines
- Textile & Pulp & Paper industries
- Jacket water cooling for compressors and engines
- Data centers needing low-noise cooling solutions
Crossflow vs. Counterflow: Quick Comparison
| Feature | Crossflow Open Cooling Tower | Counterflow Cooling Tower |
| Efficiency | Moderate but sufficient for most applications | Higher thermal performance, smaller footprint |
| Maintenance | Very easy access, low downtime | More complex internal access, higher maintenance |
| Energy Use | Lower fan and pump energy consumption | Higher pump head and fan energy |
| Noise Level | Low | Relatively higher due to water fall and enclosed design |
| Climate Suitability | Better for cold climates; less freeze-prone | Higher efficiency in warmer climates |
Best for: Applications where serviceability, low noise, and balanced performance are needed.
Counterflow towers are preferable when maximum cooling efficiency and compact footprint outweigh maintenance convenience.
Maintenance & Operation Tips
Clean fill and basin regularly to avoid buildup and maintain efficiency.
Install filtration systems to reduce fouling and scale formation, boosting energy performance by up to ~18% per study.
Use anti-algae and biocide treatments proactively, especially where sunlight exposure is high.
