The Coolbot is an invention that makes a walk-in cooler a viable option for a farm with low cash flow. By using a Coolbot instead of a conventional walk-in cooler, farmers lower expenses while still helping enhance produce quality at the point of sale.
Since 2006, Ron and Kate Khosla have sold thousands of Coolbots, a technology they developed to convert off the shelf air conditioners into a compressor unit for a walk-in cooler. Instead of purchasing a conventional cooler for $2500 or more, with about 30 seconds of modification, one can turn an A/C unit into a cooler for about $600. Further, electricity costs will be lower and the modification does not void the warranty on the A/C unit, protecting the investment for typically five years.
