Brief Introduction: Low-temperature circulating pump also know as Low temperature cooling water/ liquid circulation pump. This device adopt mechanical refrigeration, the main function is providing 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.
Product Features:1. Air-cooled and hermetically sealed compressor units (import) with dependable quality; 2. The dedicated and high-quality relays, protective devices and capacitors of the refrigerating units; 3. Digital Read Out of temperature and microprocessor controller for temperature, simple and easier to see; 4. Bigger cooling capacity and faster cooling speed, which have greatly improved the working efficiency;
Technical ParametersAccording to the volume of cryogenic cooling bath circulation pump divided into : 5L,10L,20L,30L,40L,50L,60L,80L,100L.Each volume according to the lowest temperature can divide into : -10?,-20?,-25? ,-30?,-40?,-60?, -80?,-120?.

Instructions for use1. The machine's power standard is 220 v, should be equipped with reasonable grounding system and the safety of the standard three pole socket.2. Before use, please put into the liquid medium (water, alcohol, antifreeze can also be), medium level should not lower than cold tube and 20 mm below the workbench is advisable. Don't let sand , acid-base class material or debris into the cooling system or the circulation pump, to prevent clogging or corrosion pan>and coil.3. Recurring observe the slot liquid level height, when the liquid level is too low, should be timely to add liquid medium. 4. When pump working temperature is lower, should pay attention not to open the cover. Never put your hand into the groove, to prevent frostbite.
