    High-low-temperature circulation device is the use of mechanical refrigeration to obtain low-temperature heating tube heating to obtain high temperature, the use of no leakage-free shielding pump as a circulating pump, with double-glazed reaction bath, stainless steel laminated reactor and other equipment used equipment.
    the preparation 1 before the use of the high and low temperature circulation device, the first use, open the wooden box first to the in coming and exit liquid valve installed on the inlet.
    (Note: The top of the machine marked with in and out of the fluid port, valve is the cut-off valve, valve media flow has direction, valve marked flow.
    2, the valve and reactor with hose docking, reactor import and export should be for the down, up and out, to ensure that the reactor remains full of liquid.
    3, open the high and low temperature groove plus liquid hole, add the medium to the machine to open the machine's circulation switch, so that the liquid circulates throughout the system.
    (Note: to drain the air in the system) 4, cooling media should meet the conditions of use.
    (i.e. do not freeze at low temperature, not boiling under high temperature conditions) high and low temperature circulation device set example 1, if the need for 150 degrees C temperature, the temperature control meter set to 150 degrees C to open the heating switch and cycle switch, the machine starts to work.
    2, the material in the high temperature needs to drop to room temperature, need to turn off the heating to open pre-cooling, at this time by cooling the material can be reduced to room temperature.
    3, the material needs to be lower than room temperature, the material should be lowered to room temperature, and then set to the required equipment, open refrigeration, the compressor will enter the working state, the machine began to cool down.
