Cooling Coil
A reliable component for dependable cooling-tower and condenser operation
HACST cooling-system components are selected to support efficient, serviceable operation in cooling towers and evaporative condensers. Material compatibility, operating conditions, system interfaces and maintenance access should be reviewed as part of the complete equipment design.
Specified around operating conditions and site requirements
The component specification should be considered with the equipment model, process medium, operating environment, system duty and planned maintenance routine.
- Application-led selection: the configuration begins with the actual operating duty and project objective.
- Practical integration: installation footprint, access, controls and service requirements are considered early.
- Long-term operation: material, water, airflow and maintenance considerations are reviewed for the operating environment.
Configuration and performance considerations
Overview
The heat exchange coil is the core component of closed-circuit cooling towers and evaporative condensers. It ensures that process fluids (such as water, glycol, or ammonia) are cooled without direct contact with spray water, guaranteeing system cleanliness and reducing contamination risks.
Role in Cooling Towers
Hot process fluid flows inside the coil tubes, while spray water is distributed over the coil’s external surface. Air drawn across the coil promotes evaporation, removing heat efficiently. The coil prevents fouling of the process circuit and reduces water treatment costs.
Material Options
- Hot Dip Galvanized Steel: Cost-effective, suitable for standard industrial use.
- Stainless Steel (304/316L): High corrosion resistance, suitable for aggressive water conditions.
- Copper: Excellent thermal conductivity, ideal for refrigerant-based systems.
Applications
Used in closed-circuit cooling towers, evaporative condensers, and hybrid cooling systems for industries such as HVAC, power generation, chemical processing, and refrigeration.
How to Select
- Base choice on process fluid (glycol, ammonia, water, refrigerant).
- Use stainless steel for coastal or chemical plant environments.
- Ensure tube diameter and coil surface area match required cooling duty.
