DAC series high efficiency after cooler can effectively eliminate the moisture in the compressed air after cooler connected at the back of the screw and piston compressor, the compressor can be produced by high temperature of compressed air cooled to 42 ℃ below, and can make the most of the water vapor condensation in the air the back closed, to improve the working conditions of the downstream dry cleaning equipment, avoid the problem of suspension and condensation of water.DAC series high efficiency post-cooler has two cooling methods: air - cooled and water - cooled.
