ACOS series — immersion type 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

    • Processing centers, modular machine tools, grinders, broaches, grinding machines
    • Wire cutting machine tools, electric machining machine tools
    • CNC gear hobbing , shaping and honing machines
    • Hydraulic pump stations

    Feature

    Feature

    • Evaporating coils are made from stainless steel or copper with coating surface, which are suitable for various fluids.
    • The design of open coil type heat exchanger eliminates the obstruction problem of liquid circulating system.
    • Immersion cooling prevents the spreading of undesirable gas and reduces the air pollution.
    • Made of anti-corrosive material
    • Directly installing on liquid tanks can avoid the impact from impurities , oil sludge , metal filings,contributing to the maintenance work

    Matters needing attention

    • Immersion depth as close to tank depth as possible
    • Refluxing high temperature liquids pass through the cooling coil first to exchange heat
    • Considering the change of liquid level before and after the operation of the equipment
    • Ensure smooth air inlet and outlet
