ACO-PAT series —Spindle Oil Chiller

TOBEL self-developed oil chiller utilizes forced air-conditioning cooling to control the oil temperature of mechanical equipment at constant temperature(such as hydraulic oil and lubricating oil).

Low temperature and low pressure liquid refrigerant exchanges heat with the oil in the evaporator, and evaporates into low temperature and low pressure gas. The temperature of refrigerant remains unchanged during the evaporation process.Then gas refrigerant is compressed by the compressor and compressed into high temperature and high pressure gas. When gas refrigerant enters the condenser, it exchanges heat with the indoor air. The refrigerant releases heat and comes into high temperature and high pressure liquid, and goes into the expansion valve.Throttling is a rapid cooling process, the refrigerant returns to low temperature and low pressure liquid. This cycle is continuous, so the oil can be continuously cooled.

    Scope Of Application

    • Mechanical spindle and low-speed electric spindle of CNC machine tools
    • Lubrication stations of CNC machine tool
    • Processing liquid cooling of electrical discharge machining equipment
    • Lubricating and cooling system of gearbox

    Characteristics

    • Cooling the oil temperature of spindle to ensure machining accuracy
    • Prevent thermal deformation of CNC machine tools to extend machine life
    • Prevent oil deterioration caused by high oil temperature
    • Maintain oil viscosity and avoid oil vibration
    • Simple operation, the control system adopts switchable LCD computer controller
    • Varied control methods of "fixed temperature" and "synchronized room temperature" , users can choose according to actual needs
    • With "fixed temperature" and "room temperature homology" two control modes, users can choose according to actual needs;
    • Multiple protection functions with passive alarm terminals, the fault signals can feedback to the CNC system timely
