A cooling tower serves as a critical heat rejection system, transferring excess heat from industrial processes or HVAC setups to the atmosphere mainly via water evaporation. By cooling recirculating water, it sustains efficient equipment operation across sectors like power generation and manufacturing. Delta's FRP Cooling Tower models stand out for their compact, resilient builds suited to varied applications.
Cooling towers are grouped by draft method (natural or mechanical) and flow patterns (counterflow or crossflow). Mechanical variants include forced draft (base fans) and induced draft (top fans), with evaporative models leading in industrial efficiency. Delta focuses on mechanical counterflow towers
Approach is the gap between cooled water temperature and ambient wet-bulb temperature (e.g., 85°F outlet versus 78°F wet-bulb = 7°F approach). Typically, cooling towers are designed for a 4°C approach to keep costs economical; however, maintaining the same range with a 3°C approach demands greater capacity, raising expenses. We advise against approaches below 2.7°C. While a tower might hit 2°C, it's rarely assured. Notably, CTI rejects approaches under 2.78°C (5°F). Our solutions strike an optimal balance for Gulf energy efficiency.
Fans create the airflow that helps water evaporate and cool down faster—our axial ones in induced draft setups pull air up evenly, with speed adjustments to cut power use. Delta's fans feature aerodynamically designed blades with variable pitch angles, and they're statically or dynamically balanced for low vibration and quiet, smooth running.
Pultruded FRP (Fiber Reinforced Polymer) emerges from a pull-through-resin-and-die process, yielding strong, consistent profiles with high strength-to-weight, corrosion immunity, and stability. It's prime for cooling tower structures in tough exposures. Delta harnesses it in the DPC-70 series for top-tier resilience.
