Cooling Towers
Model Number: EC1000V
Benchtop apparatus for demonstrating the operating characteristics of an evaporative cooling tower.
Overview
This low-maintenance, bench-mounting product contains a heated water tank, a pump, a ducted fan and an instrument panel. Each cooling column fits securely to the heated water tank.
An electronic controller ensures a constant heated water temperature throughout the tests. The centrifugal pump delivers the heated water to a spray nozzle at the top of the column. The water sprays into the column, passing over packing inside the column and returning to the heated water tank. The fan directs air upwards through the column in counter flow to the water, extracting the heat. Electronic sensors measure the air and water flow, humidity, pressures and temperatures at key points, shown on clear, multi-line displays. This gives all measurements needed to understand the evaporative cooling tower operation. Controls for the fan and water circuits allow the students to adjust the flow rates for a full range of experiments. A clear tube above the heated water tank allows the user to measure the water lost to evaporation.
The Cooling Towers apparatus comes with one tower as standard, for base experimentation. For comparison and additional experiments, TecQuipment offer four optional cooling columns. Each column is of high-grade clear acrylic material, allowing the user to see the complete process including the water distribution and packing arrangement. The equipment does not need a computer, as the displays show all the measurements. When connected to a suitable computer, VDAS® Onboard collects and displays accurate, real-time data quickly and easily, and also displays live psychrometric charts.
Features
- Includes TecQuipment’s Versatile Data Acquisition System (VDAS® Onboard) for live displays of air temperatures and relative humidity using a psychrometric chart
- Measures evaporated water loss for a complete understanding of the cooling process
- Includes one column with packing for immediate experimentation potential
- Three extra interchangeable columns containing different packing densities and arrangements further extend experimental capabilities
- An optional interchangeable column with no packing demonstrates free-fall cooling
- All columns have clear sides for a full view of the heat transfer process
- Variable water and air flow controls to maximise heat transfer experiments
