Description
Russell Coil 103079002 Defrost Termination and Fan Delay Switch controls the sequence of defrost termination and evaporator fan operation according to temperature conditions. It terminates the defrost cycle when the preset temperature is reached and delays fan operation until the evaporator coil reaches the required temperature. Installed in compatible commercial refrigeration equipment, the switch coordinates with the refrigeration control circuit during defrost operation. Compatible refrigeration equipment can use this control arrangement to maintain proper cycling between defrost and fan operation in HVAC systems. Its operation supports controlled defrost completion, proper fan timing, stable refrigeration cycles, and consistent equipment operation.
