Product Description
Mach Cooling’s closed cross flow cooling towers, part of the AHC series, are advanced cooling solutions designed for energy-efficient heat dissipation in industrial and commercial settings. With a cross-flow design, closed-loop circulation, and a lifespan of 10 to 15 years with proper maintenance, these towers minimize water loss and scaling, ensuring reliable performance. Ideal for high-speed railways, metallurgy, chemical industries, and HVAC systems, they offer low-noise operation and easy maintenance. Compare with our closed circuit cross flow cooling towers for similar configurations.
The closed cross flow cooling tower uses a closed-loop system for efficient heat exchange:

Select a well-ventilated site free from heat sources or obstructions for optimal airflow.
Ensure the site’s load-bearing capacity meets the tower’s weight requirements.
Construct the foundation with a maximum elevation error of ±5mm.
Maintain adequate spacing for air intake and maintenance access.
Avoid open flames or welding near the tower; take precautions if necessary.
Before operation, verify secure connections, lubricate components, and check wiring.
Assign professional operators for regular inspections and maintenance logging.
Cools high-temperature fluids for efficient turbine operation in power plants.
Manages heat from chemical processes to ensure safety and efficiency.
Handles cooling for smelting and forging to maintain equipment stability.
Provides reliable cooling for server equipment to ensure optimal performance.
Supports precise temperature control for manufacturing processes.
Manages heat from processing and packaging for efficient production.
Regularly clean dust, oil, and debris from the shell and remove scale from the heat exchange coil and spray filter to maintain efficiency.
Use soft water in the heat exchange coil to prevent scaling. Regularly clean spray water (tap water) to avoid scale buildup on copper pipes.
Ensure sealed inlet pipes, fill pipelines with liquid, monitor motor current, supervise operation, avoid shutting off cooling water during high temperatures, and inspect for noise/vibration annually.
Use clean, particle-free lubrication, avoid dry friction, and rotate the pump before starting to prevent seal damage.
Process fluid flows inside coils, with spray water covering the outer surface. Heat transfers through the coil walls, creating vapor that is expelled by fans, while water is recirculated.
Suppresses scale formation for high-temperature fluids.
Large maintenance space for easy access.
Low noise operation, ideal for residential areas.
Energy-efficient with up to 50% savings via digital control.
Cross flow towers have horizontal airflow, require less area in some applications, and are easier to maintain. Counter flow towers have vertical airflow and a more compact structure.
Suitable for high-temperature fluids or large temperature differences, and ideal for parallel multi-unit setups in industries like power, chemical, and data centers.
With proper maintenance, the lifespan is typically 10 to 15 years, depending on materials, operating conditions, and maintenance practices.
Clean debris from air intake and water basin; adjust V-belt of reducer.
Use soft water in coils and clean spray water to prevent scaling.
Monitor pump operation, ensure sealed pipes, and avoid cavitation.
