YSBLG series screw brine unit is a low-temperature brine unit with imported semi-closed screw refrigeration compressor as the main machine, which is characterized by high single-machine power. By combining multiple units, it can obtain more energy than piston compressor, and it occupies a small area, runs smoothly, reliably and has low noise. Its advantages are: because of its unique structure, there is no danger of liquid collision during gas compression, which provides a prerequisite for safe and reliable operation of the unit. The brine unit has a variety of specifications for users to choose from. Its refrigerating capacity ranges from 65 kW to 1600 kW, and it can provide low-temperature brine at 0 ~ 30℃. It is mainly used for rapid cooling and temperature control of reaction vessels and materials in chemical, pharmaceutical, wine-making and ice-making fields. The refrigerating capacity of the unit can be stored by a large capacity of coolant, which can make up for the temperature instability caused by the large and small consumption and uneven use.
