Overview
Low-temperature circulating pump also know as Low temperature cooling water / liquid circulation pump. This device adopt mechanical refrigeration, 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.
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)It can be matched with a variety of instruments (rotary evaporators, fermentation tanks, chemical reactors, freeze-drying equipments, pharmaceutical reactors, etc.);
(5)Bigger cooling capacity and faster cooling speed, which have greatly improved the working efficiency;
(6)It can effectively ensure the normal use of all kinds of precision instruments under the working conditions such as lacking water, the poor quality、pressure and temperature of water, and high temperature;
(7)The flow of circulating pump can be either adjusted or customized, which has greatly met the actual needs of different customers;
(8) All models of this machine can be matched reasonably between the low temperature and the cooling capacity or capacity basing on the requirements of customers.
