Electric defrost systems offer several advantages over hot gas defrost systems. Electric defrost systems are more energy-efficient, as they only consume power during the defrost cycle, whereas hot gas defrost systems require continuous compressor operation. Electric defrost systems are also less complex and require less maintenance, as they do not involve refrigerant flow and pressure changes. Additionally, electric defrost systems can be more effective in low-temperature applications, as they can provide a more consistent and controlled heat source.
