Century Refrigeration’s Centinel™ Defrost Control System Significantly Reduces Refrigeration Systems’ Energy Usage

Century Refrigeration announces the release of the new Centinel™ Intelligent Defrost Control System. This control system improves refrigeration systems’ energy efficiency, eliminates icing and fogging, and reduces operating costs. A traditional defrost control system relies upon a room thermostat, defrost time clock, and defrost termination/fan delay thermostat for mechanical control of the refrigeration system. The Centinel instead consists of a microprocessor-driven controller, 4 temperature sensors, and a suction transducer. The microprocessor, paired with the advanced, sensitive temperature sensors, controls the system with a precision and accuracy unmatched by mechanical controls. The Centinel reduces the energy used by the system by precisely controlling superheat and fans, reducing compressor run time, and implementing demand defrosts. It uses a unique self-learning algorithm that allows it to automatically adjust to changing system conditions, making it customized to each individual evaporator. This industry-leading defrost control system was designed for a rapid ROI and exceptionally long service life. The Centinel can be used with both new and existing applications. As the controller is not refrigerant specific and can be easily configured for use with mechanical or electronic expansion valves, it is appropriate for use in a wide range of refrigeration applications.
