What is the minimum required temperature at the nozzle of Type I de-ice fluid for it to be effective?

The effectiveness of Type I de-ice fluid is highly dependent on its temperature at the nozzle during application. For Type I fluid to properly penetrate and remove ice, it must be heated to a minimum temperature of 140 degrees Fahrenheit. At this temperature, the fluid has the right viscosity and thermal properties to effectively melt any existing ice and prevent additional accumulation. Using fluid at or above this threshold ensures that it can perform its intended function in a safe and efficient manner. Lower temperatures might hinder the fluid's ability to adhere to and effectively de-ice surfaces, making 140 degrees Fahrenheit the critical minimum for optimal performance.
