Set Free Variable Refrigerant Flow (VRF) systems by Hitachi are an extremely powerful cooling solution for all kinds of residential, industrial and official establishment units.
These systems are designed to thoroughly save on energy usage while being reliable, flexible and easy-to-install. They are capable of impressively low noise levels with noise reduction preference mode (option). The intermediate pressure performance is drastically improved by using a release valve and optimizing orbiting scroll lifting force in the improved new compression mechanism. Performance is greatly improved by the high efficiency DC inverter compressor and 100% load compressor, and loss-less energy saving operation is achieved (depending on the building). Since the current is self-detected and demand control performed automatically, no signal wiring work is required. Conventional demand control using demand signals is also available, and you can select various operations as required.
