Open Tower Systems: High Thermal Efficiency for Robust Industrial Cooling
For many heavy-duty industrial and large-scale HVAC applications, the Open Tower (or Open Circuit Cooling Tower) remains the standard for cost-effective and thermally efficient heat rejection. Our open towers are designed for direct contact operation, where the warm process water is directly exposed to the circulating ambient air. This simplicity of design allows for the most intimate heat transfer, enabling the system to cool water to temperatures closest to the wet-bulb limit, a critical factor for achieving high system efficiency in many industrial cooling loops.
The primary advantage of our Open Circuit Cooling Towers lies in their superior thermal performance and lower initial capital investment. By foregoing the complexity of a heat exchange coil in the primary loop, the open design achieves an exceptionally low approach temperature, translating into colder water returning to the chiller or process equipment. This enhanced cooling capability can significantly improve the Coefficient of Performance (COP) of connected chiller plants and boost the operational efficiency of manufacturing processes, such as plastic molding, chemical processing, and general machinery cooling, where a consistent, low temperature is vital for product quality and throughput.
A critical design feature across our open tower portfolio is the use of advanced, robust materials. Recognizing that the water is exposed to the atmosphere, potentially introducing dirt, debris, and atmospheric gases, our towers feature anti-corrosion components and strategically placed, easy-to-access sumps and filtration points. Furthermore, we equip our Open Evaporative Cooling Systems with highly efficient Drift Eliminators. These specialized components are designed with a maze-like structure to capture water droplets (drift) carried out by the exhaust air, significantly reducing water loss and preventing the discharge of potentially concentrated chemicals into the surrounding environment, ensuring environmental compliance and resource conservation.
