Chiller water temperature if too low, the controller panel will show E3 alarm, the reason is generally in the northern winter time, the night ambient temperature is too low and stop using the chiller, so that the chiller cooling water temperature drop to the next day when the chiller is turned on again and the water temperature is too low alarm, only need to add hot water to improve the temperature of the water to be the water temperature of the chiller is higher, the alarm will naturally be eliminated. The alarm will be eliminated naturally.

The working principle of the chiller:
Refrigerant (i.e., refrigerant) in the evaporator to absorb the heat of the cooled material and vaporize into steam, the compressor will continue to produce steam from the evaporator and compressed, compressed high-temperature, high-pressure steam is sent to the condenser to the cooling medium (such as water, air, etc.). Medium (such as water, air, etc.) exothermic condensation into a high-pressure liquid, in the throttling mechanism to reduce the pressure into the evaporator, vaporized again, absorbing the heat of the cooled object, and so on and so forth in the cycle.
Heating, refrigerant through the four-way valve to change the direction of refrigerant flow, refrigerant flow direction and refrigeration is just the opposite, the refrigerant first through the evaporator, and then back to the condenser, and finally back to the compressor.
Chiller use:
1, the chiller can be used in supporting vacuum equipment. This type of chiller also meets the needs of high-quality vacuum equipment, such as molecular pumps, small vacuum coating machine.
2, chiller used in supporting medical laser equipment. This type of chiller unique water quality treatment characteristics, making it the ideal choice for medical laser equipment supporting supporting laboratory equipment. This series of chiller is also widely used in atomic absorption spectrometry analyzer, fermentation devices, reactors, electrophoresis instrument.
3, the chiller can be used to supporting experimental condensing equipment. Such as rotary evaporator, distiller, condenser tube, with high and low temperature control, temperature stability, condensation efficiency, can effectively improve the recovery rate. At the same time its fluid purification function, can avoid the circulation pipe clogging, growth of microorganisms.
4, chiller used in supporting semiconductor laser equipment. Semiconductor laser equipment due to its special structure, the water quality requirements are higher.
