The Centinel™ Intelligent Defrost Control is an option with each of the company’s system arrangements. It is an electronically operated evaporator controller designed to save energy throughout the refrigeration cycle, help protect the equipment, and help protect the system owner’s valuable product. The controller also simplifies the monitoring and control of the room temperature while optimizing equipment performance. The defrost control system consists of a microprocessor-driven controller and up to four separate temperature sensors. The sensors provide necessary feedback from the refrigeration system to allow the controller’s logic to work. The defrost control utilizes a series of algorithms to ensure the evaporator is providing maximum efficiency. Among these is a self-learning algorithm that allows the controller to adjust to changing conditions, said the company. Because it is adaptable, the defrost control customizes itself to each individual evaporator. The Centinel utilizes a communication system known as the Centinel™ Network; it uses Ethernet communication, which replaces the need for a serial network. The Centinel™ Network gives users the ability to connect the controller to any computer with an Internet browser and see the current state of the controller.
