A water chiller is a mechanical device used to facilitate heat exchange from water to a refrigerant in a closed loop system. Adoption of low-temperature liquid circulation equipment of compression refrigeration methods can cool the tube, the reaction bottles directly and so on to have chemical reaction under low-temperature and store chemical and biological products under low-temperature. Besides, it can also be combined with rotary evaporator, vacuum freezedrying box, muti-purpose circulating water vacuum pump.
