10L Low Temperature Liquid Coolant Circulation Pump
10L Low Temperature Liquid Coolant Circulation Pump
Brief introduction
Low-temperature liquid coolant circulation pump also know as low temperature cooling water / liquid circulation pump. This device adopt mechanical refrigeration cryogenic liquid cycle equipment, the main function is provide low temperature liquid, low temperature water bath. It can also connect with rotary evaporator, vacuum freeze drying oven, cycle water vacuum pump, magnetic stirrer and so on, to achieve the chemical reaction or drug store under low temperature condition. We can also be customized large-capacity according to the needs of users.
Features
♦ Air-cooled hermetic imported compressor group, reliable quality.
♦ Exclusive and high quality of relays, protectors, and capacitors.
♦ Microprocessor controller, displays clear, simple operation.
♦ It is a good ancillary equipment of various instruments, such as rotary evaporators, glass reactors, freeze drying equipment, drugs reactors, etc.
♦ Large cooling capacity, cooling speed, and greatly improve working efficiency.
♦ Under the condition of poor water quality, water pressure, water temperatures and high temperature, our machine can effectively protect all kinds of precision equipment for normal use.
♦ Circulation pump flow can be adjusted or customized to meet the practical needs of different customers.
♦ All models of the machine temperature and cooling capacity can be customized according to the customer's actual needs, to meet the different experimental match.

Common faults and troubleshooting(See table below)
Symptom | Failure cause | Troubleshooting |
CNC table does not show | The power is disconnected | Find the power cord whether is connected or loose. |
Panel displays ”οο” | Sensor problem | Repair or replacement |
Not cooling | Check whether the thermostat is set correctly, the press is working, AC contactor is damaged, the refrigerant leak is serious. | Reset the thermostat parameters, repair or replace AC contactor, find the leak site, please refill refrigerant after repaired. |
Slow cooling | See whether the coolant is sticky. Whether condenser fan is normal, the condenser filter dust is thick, whether refrigerant leakage, check if there are any oil plug or ice jam of the system. | Replace the secondary refrigerant (the coolant freezing point should be‹-85℃, boiling point should be›50℃). Repair or replace the motor. Look for leakage and re-charging refrigerant and completely remove the dust on the condenser filter. Check the oil separator, capillary, filter dryer, expansion valve if there is problems, repaired or replace it. |
Machine is smoky | AC contactor, power transformer damage | Repair or replace |
Noisy | Inside the machine have loose parts | Reinforcement the screws of compressor, fan, condenser. |
Not cycle | Circulating pump system have problems | Dredging system, repair or replace the circulating pump. |
