Profile: Refricenter Of Miami, Inc. is a distributor of air conditioning, refrigeration and ventilation equipment, parts and supplies. Our product line includes Classic DC InverterTGM inverter, TGM inverter high wall systems, pre insulated copper coils. Our brands include Atco Flex®, Bristol® and Classic®. Our air-conditioners bearing the inverter tag use a variable-frequency drive to control the speed of the compressor motor. The variable-frequency drive uses a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency. The AC current is used to drive a hermetic brush less motor in the compressor. Our pre insulated coils are available in various sizes.
