Product Overview
The Counterflow Open Cooling Tower by HACST Cooling provides powerful, space-efficient evaporative cooling tailored to demanding industrial and commercial environments. Featuring a vertically opposing airflow and water flow design, it maximizes thermal performance while occupying minimal footprint—ideal for tight spaces or high-load applications.
Key Features & Advantages
- Superior Thermal Efficiency – Pressurized spray nozzles and counter-directional airflow enable enhanced heat transfer via uniform water distribution across the fill .
- Compact Footprint – Vertical design saves ground space, perfect for urban sites or multi-tower installations.
- Reduced Freezing Risk – Spray water breakup and fill configuration improve freeze resistance in cold climates .
- Lower Drift and Sunlight Exposure – Enclosed design limits water drift and protects fill and distribution systems from direct sunlight .
- Ideal for High-Load Environments – Perfect for data centers, power plants, pharmaceuticals, and district cooling where efficiency per footprint matters most.
Working Principle
Hot process water is sprayed via high-pressure nozzles downward through the fill media. Meanwhile, air is drawn upward in direct opposition to the water stream. This counterflow arrangement enhances heat exchange efficiency, with cooled water collected at the basin for recirculation.
Applications
Suited for:
- Data Centers — High thermal loads in compact space
- Power & District Cooling — Efficiency-critical environments
- Pharmaceutical & Clean Process Industries — Sensitive applications requiring precise temperature control
- Urban Installations — Where space optimization is vital
Comparison: Counterflow vs. Crossflow
| Feature | Counterflow Open Cooling Tower | Crossflow Open Cooling Tower |
| Thermal Efficiency | Very High — optimized spray and airflow pattern | Moderate — gravity distribution limits performance |
| Footprint | Compact, vertical layout | Larger plan area |
| Maintenance & Access | Limited internal access, may require shutdown | Easy maintenance, often accessible during operation |
| Pump Energy Requirement | Higher — due to pressurized nozzle system | Lower — gravity-fed water distribution |
| Noise & Drift | Moderate — enclosed design suppresses drift | Lower noise, easier access |
| Climate Suitability | Best in warm/hot climates | Better freeze resistance |
Maintenance & Operation Tips
- Regular Inspection of spray nozzles and distribution trays—enclosed design may require periodic shutdown for cleaning .
- Water Treatment to prevent scaling and biofouling; consider microsand filtration to boost cooling efficiency by up to 18% and save energy .
- Fan & Motor Maintenance—ensure proper lubrication and alignment for sustained performance .
- Drift Eliminator Checks—inspect semi-annually for integrity to curb water loss and health risks .
- Legionella Prevention—regular monitoring and biocide application are vital for safe operation .
