An example of the dollar savings expected for refurbishing a tower vs. replacement is when Bond Water Technologies completely refurbished four (4) 200 ton cooling towers (800 tons total) at a cost of approx.$80,000.00 vs. the cost of new towers quoted at $100,000.00, plus installation costs.ooling Tower Replacement can be a costly proposition and the average life expectancy of a commercial cooling tower, according to most manufacturers, is 15 â 20 years, before they need to be rebuilt or replaced.
The cooled water is collected at the bottom of the tower and pumped back into the plant or building for reuse. Cooling towers provide large scale air-conditioning where land and (or) water are expensive, or regulations prohibit the return of once-through cooling waters (1) .ooling towers are primarily used for heating, ventilation, and air conditioning (HVAC) and industrial purposes. Cooling towers provide a cost-effective and energy efficient operation of systems in need of cooling. More than 1,500 industrial facilities use large quantities of water to cool their plants (2) .
