Video Description
Product Description
The low-temperature coolant circulation pump (machine) adopts imported air-cooled fully-enclosed compressor refrigeration and microcomputer intelligent control system. Provide a low-temperature circulating cooling water (liquid) flow or a low-temperature constant-temperature water (liquid) flow to meet the needs of using cooling water and cryogenic liquids to cool or thermostat instruments(Such as rotary evaporators, fermentors, electron microscopes, cryogenic chemical reactors, electron energy spectrometers, mass spectrometers, densitometers, freeze dryers, vacuum coating equipment, biopharmaceutical reactors, etc ).
Product Advantages & Features
● Air-cooled design saves valuable water resources. ● The host and the cold liquid tank are made separately. The circulation pump can output the coolant in the tank (machine) and cool the cooling device. ● All operations are completed by pressing the touch soft key on the microcomputer intelligent controller. The operation is simple and intuitive. ● Delay, overpressure, overheating, over-current, cut-off and other protections. ● Circulatory system adopts ANSI 304, 316 stainless steel, with anti-corrosion, anti-rust, anti-low temperature liquid contamination function. ● The software lock function of the microcomputer can lock the setting value of each parameter of the system. The irrelevant personnel cannot change the parameters at will.
Product Applications 
The heating refrigerated circulators are widely used in chemical industries , pharmaceutical plants ,
biological engineering , kilo labs , pilot plant and other related areas . They can control the temperature of mixing tank ,
jacketed glass ( metal ) reactors, thermal test platform and etc .

Single-layer glass reactor can directly heating or cooling, it is similar to water or oil bath, inferior in temperature control aspect; while double-layer glass reactor has interlayer between two layers, we can inject water or oil through temperature control equipment and form circulating system, in this way, no matter cooling or heating, its temperature control property is better. 2.How to decide which glass reactor I should buy? Single-layer or double-layer? According to first question, please depend on specific heating or cooling requirements. 3.What is the glass texture? Full set of glass part is produced by G3.3 borosilicate glass, owns excellent chemical and physical properties. 4.What’s the loading capacity of double-layer glass reactor? Loading capacity of glass reactor generally is 1kg, use hot water and oil to do negative pressure heating. 5.What kind of oil does the reactor use to heat? For temperature around 130℃, use silicone oil, glycerinum or 32# machine oil. 6.Is it easy to wash the reaction bottle? Big access opening, convenient to wash. 7.What kind of payment term do you accept? Normally we accept TT , Alibaba Escrow, and L/C. The exactly term with be discussed during the deal. 8.How will you delivery these goods? It will be decided according to your quantity. Normally we will choose International Express, Air and sea.. 9.How to package the products? We package products in dedicated carton, you can order Non Fumigation wooden case if has special requirements. Our Beliefs We believe , only the most excellent quality , most leading technology , most complete solution and best service could make Ningkai Instrument more and more better in the future .
