Industrial cooling towers
Evaporative cooling towers for industrial process loops. Our 150-ton, 350 GPM reference unit was developed by ValensAir and is installed and in service at a pharmaceutical plant.
Heat out. Cool water back to the process.
A cooling tower rejects process heat to the atmosphere. Warm water from condensers, heat exchangers or process equipment is spread over fill media while a fan draws ambient air through it. A small fraction of the water evaporates, carrying heat away, and the cooled water collects in the basin and returns to the process.

- Hot water from process
- Cooled water
- Ambient air in
- Warm, saturated air out
Operating principle
Hot water is distributed
Water returning warm from the process is pumped to the top of the tower and spread evenly across the fill by a distribution header and nozzles.
Air is drawn in
An induced-draft fan pulls ambient air in through the inlet louvers at the base of the tower.
Heat and mass transfer in the fill
Water runs down the fill surfaces as a thin film while air rises against it. Evaporation of a small fraction of the water removes heat from the remainder.
Droplets are captured
Drift eliminators above the distribution system catch entrained droplets before the warm, saturated air leaves through the fan stack.
Cool water returns
Cooled water collects in the basin and is pumped back to the process to absorb heat again.

Thermal duty
Heat load, circulating flow, range and approach to wet-bulb fix the size of the tower. We size against your site climate data, not a catalogue default.
Water quality
Scaling, fouling and biological growth decide fill selection, materials and treatment provisions.
Serviceability
Fill, nozzles, eliminators and drive components are arranged so they can be inspected and replaced on site.
Applications
- Process water cooling for production equipment
- Condenser water for chillers and refrigeration plant
- Heat exchanger and jacket cooling loops
- Plastics, chemical, food and pharmaceutical utilities
Configuration options
- Capacity and flow sized to the process heat load and site wet-bulb
- Fill media selected for water quality and fouling tendency
- Basin, make-up and blow-down connections to suit the plant
- Fan and motor selection for duty, noise and energy
- Access platforms, ladders and service openings
- Water treatment and side-stream filtration provisions
