One key component to an efficient walk-in cooler is its insulation. A standard walk-in cooler will have between 2 and 4 inches of Styrofoam insulation within its walls and a rubber sealing gasket around its door to help ensure that it is both airtight and well-insulated against the temperature of the air outside.
CoolBot Systems Take Longer to Lower the Temperature in the Cooler. The CoolBot can get most walk-in coolers down from ambient temperature to 45Â°F (7Â°C) in about 20 minutes. However, it can take longer (about another 30 minutes) to hit 40Â°F (4.4Â°C) and will take increasingly longer the farther you go down in temperature.
