Centinel improves refrigeration systems’ energy efficiency, eliminates icing and fogging, and reduces operating costs, says its manufacturer. The intelligent defrost control system consists of a microprocessor-driven controller, four temperature sensors and a suction transducer. Paired with the advanced temperature sensors, the microprocessor reduces the energy used by precisely controlling superheat and fans, reducing compressor run time and implementing demand defrosts. Its self-learning algorithm allows it to automatically adjust to changing system conditions.
