Product features:
GR212 series machine has the following advantages:
        1. Compact structure, integrated design of reversing device, heat exchanger and pump, and 25% space can be saved due to no external circulating pipeline.

        2. Energy conservation and high efficiency, compact design of heat exchanger without loss of heat energy.
        3. Main pump motor controlled by variable frequency and stepless control of flow rate can reach synchronous dyeing effect in accordance with different technological parameters of dyeing, saving energy consumption during startup and load shedding operation.
        4. Unique and stable reversing device, no pause of liquid flow during reversing, increasing number of cycles and improving dyeing uniformity.

        5. Multifunction intelligent computer control, simplifying operations of multiple functions including water intake, drainage, internal flow and external flow, etc.

        6. Pressure dehydration, reducing water content absorbed on cheese.
        7. 1:6 low bath ratio dyeing, saving dye, chemical additive, steam and water, and reducing discharge.

        8. Quickly and easily unloading creels, alleviating labor intensity and saving work efficiency
