GREE MACHINE WATER COOLER GPRS monitoring module facilitates centralized management of units, greatly reducing management costs, labor costs and labor intensity. EASY MAINTENANCE ( Optional stainless steel filter ) Nylon screen for official match, with optional stainless steel filter. Easily cope with the harsh environment of the machine tools, also not afraid of all kinds of cooling media and chip waste with strong anti-corrosion ability. The integral water tray allows the unit to prevent condensate from splashing around during the process, eliminating the installation process and facilitating after-sale maintenance.
LOW NOISE Adopt noise reduction motor and optimize the compressor suction pipe to control noise and sound quality. CFD simulated and designed a new type of high efficiency axial fan to optimize wind blade shape; while the blade edge curvature is more reasonable, more efficient, and less noise. Flexible pipe Optimize compressor suction pipe and control low frequency noise to achieve good sound effect. Noise reduction motor Adopt the new noise reduction motor,with stable control speed and good mute effect.
