Water defrost can only be effectively incorporated at application temperatures above?

Water defrost systems are primarily designed to operate effectively when the application temperatures are at or above freezing, specifically 32°F. This is because ice forms on coils and surfaces at temperatures below freezing, inhibiting the efficiency of the defrost process. To effectively remove ice, the water needs to be able to flow as a liquid and not remain in a frozen state.

When operating at temperatures below this threshold, ice can build up, making it difficult for a water-based system to defrost properly. Thus, specifying that water defrost can only be effectively utilized at temperatures above a certain point is crucial, underscoring the necessity of maintaining temperatures conducive to liquid water for successful operation.

While defrost systems might still operate at lower temperatures, without adequate temperatures above 32°F, the efficiency and effectiveness of the water defrost application are severely compromised, making it a critical consideration for operators managing such systems.
