Tower Tech open circuit (or open loop) cooling towers redefine what a cooling tower can do. First developed in 1991 and now with over 5,000 towers installed worldwide, Tower Tech cooling tower technology minimizes life cycle costs by maximizing efficiency. Tower Tech also offers innovative closed circuit (or closed loop) cooling towers. Combining the cooling tower operation and heat exchanger into a single, cost-effective package prevents contamination for systems where a clean process is critical.

What Makes a Tower Tech Open-Circuit Tower the Superior Choice?
Tower Tech’s modular cooling towers are the highest-quality towers available on the market. With the best-in-class operational expenses of any cooling tower, a Tower Tech cooling tower has the lowest total cost of ownership. It also requires less maintenance and uses less water and chemical resources than conventional cooling towers, all while maximizing real estate and avoiding Legionella bacteria and corrosion. Our open-circuit tower provides redundancy that exceeds N+1 requirements.
Our open-circuit cooling tower, as the name suggests, has a unique thermal transfer design that rejects heat into the atmosphere through direct contact of the process water with the air. The heat exchange system cools the water in the tower via innovative fan placement and internal components to channel the air. As the water moves down through our towers, it encounters multiple, patented features that maximize efficiency.
Variable Flow Rotary Nozzles
Our patented water nozzle designs distribute the water in a square pattern over the tower’s fill media to use the full surface area and cool more efficiently while avoiding clogs.
Water Collection System
Tower Tech’s patented water collector system moves inlet air into the fill media and channels water flow into the FlowThru™ Basin while providing a leak-free barrier. This protects the tower’s mechanical components, allowing the motors to be placed at the bottom of the cooling tower and allowing for easy, ground-level maintenance.
XchangeTech Fill Media
Tower Tech’s OEM fill media uses a unique water fall technology that optimizes the heat exchange surface are via materials design and engineered air/water patterning. The cross-corrugated PVC film is designed to operate under most thermal, process and water quality conditions while resisting biological and chemical degradation.
FlowThru Basin
Unlike the low velocity, cold water, settling basins common to conventional cooling tower designs, this patented basin has high water velocities in the channel that continually scrub the walls and floor to eliminate the build-up of sediment and potentially bio-hazardous material. The enclosed design eliminates any contact with sunlight, which stops algae and other biological growth. This reduces chemical use and mitigates the risk of deadly Legionella.
Bottom Mounted Direct Drive Fans
Ambient air is pushed up through the tower to perform the cooling process. Tower Tech uses a series of smaller fans that increase the efficiency of our open loop towers and add redundancy to maintain uptime. The cool intake airstream protected from the elements and easily accessible at ground level, compared to the traditional side- or top-mounted fan design.
Drift Eliminator
Perhaps Tower Tech’s best-known efficiency story, our drift eliminator captures water that escapes the tower as mist in the air. The final drift rate of a Tower Tech tower is an industry-best 0.0004%.
