The Hoshizaki 4A3277-01 Hot Gas Solenoid Coil 120V with Wire Leads regulates the flow of hot gas in refrigeration systems, resulting in effective defrost operation and consistent cooling performance. When activated, this coil generates a magnetic field that activates the solenoid valve, regulating refrigerant movement. Its 120V architecture ensures consistent compatibility with typical electrical systems, and the attached wire leads make installation and connecting easier.
