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.
Therefore: 1 Refrigeration Ton = 2000 Pounds x 144 BTU per Pound / 24 hours = 12,000 BTU's per Hour The idea of Refrigeration Ton made it easier to sell equipment. The machine's capability could be compared to a quantity of ice.elting ice at 32 degrees Fahrenheit requires 144 BTU's per pound to become liquid at 32 degrees Fahrenheit. The Refrigeration Ton was defined as the heat absorbed by one ton of ice (2000 pounds) causing it to melt completely by the end of one day (24 hours).
