PTZ series adopts HMI which allows start, stop, pressure setting, running data indication, etc. It is easy for workers to set up working pressure then the CTS will automatically stabilize the fluid pressure by quick adjusting the flow according to the I.D. of tools. The sufficient cooling, cutting and lubrication achieve a better quality of products and longer lifetime of tools. Built-in buffer tank and dual filter system support faster flow change and cleaner fluid quality. The superior plunger pump equipped in this module could not only convert frequency precisely, but decrease ineffective power consumption and the rise of fluid temperature.
