NuCool technology combines the best features of current cooling systems to create a brand new technology that achieves temperatures as low as 37-degree F (based on 70-degree F ambient room temp), which was not possible with prior refrigerant-free models. NuCool has no compressor and runs whisper quiet while also achieving low power consumption. NuCool provides a technology in small refrigerators that consumers find so useful for apartments, dorms, bars and other small areas.
