DLSB-5 series low-temperature cooling liquid circulating pump, also known as low temperature pump, low temperature circulating pump, low temperature cooling water circulating pump, water tank volume is 5L, min no-load temperature is between -15℃~-123℃, best environment temperature is 5℃~25℃. It adopts PT100 temperature sensor, large measurement range, excellent pressure-resistant properties, use chlorodifluoromethane(R22) as refrigerant, excellent refrigeration effect. DLSB-5 series of low-temperature cooling liquid circulating pump is a low temperature liquid refrigerant equipment which takes mechanical forms to refrigerate. It has the function of providing a cryogenic liquid, low temperature water bath. It can be combined with the rotary evaporator, glass reaction kettle, vacuum freezing drying oven, circulating water vacuum pump, magnetic stirrer and other instruments to proceed multi-functional chemical reaction or store drugs under low temperature condition. DLSB-5 can be provided to meet the dual requirements of cooling water of temperature and pure water. The equipment is especially suitable for the need of keeping working under the condition of low temperature , chemical, biological, physical laboratory, medicine and health care, chemical industry, food industry, metallurgical industry, universities and colleges, scientific research, genetic engineering, polymer engineering laboratory equipment necessary(large capacity low temperature cooling liquid circulating pump can be customized according to users' need).

Product Features of DLSB-5 series low-temperature cooling liquid circulating pump:

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. Refrigerating capacity is large, cooling speed is fast, greatly improve the working efficiency.
5. In the lack of water sources, water quality, water pressure, water temperature is bad in the environment and under the high temperature working conditions, which can effectively protect the normal use of all kinds of precision equipment and instruments.
6. Circulation system adopts anticorrosion materials, which has the function of antirust and anticorrosion, cryogenic liquid pollution prevention.
7. 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;
8. The flow of circulating pump can be either adjusted or customized, which has greatly met the actual needs of different customers;
9. 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.
10. It can be matched with a variety of instruments (rotary evaporators, fermentation tanks, chemical reactors, freeze-drying equipments, pharmaceutical reactors, etc.);
11. This equipment combines circulation with cooling function as a whole, which saves much space.

This equipment can match with rotary evaporator, vaccum freezing dying oven, magnetic stirrer, diaphragm vacuum pump and other instrument to proceed chemical reaction and store drugs under low temperature.

Low temperature coolant circulation pump with constant current and voltage, circulating fluid can meet the electron microscopy, electric probe, ultra-high vacuum sputtering, X-ray machines, lasers, accelerators and other valuable equipment’s need of cooling. For the purification of high purity metals, rare elements, environment experiment and magnetron sputter, vacuum coating and other large equipment, DLSB-5 can be provided to meet the dual requirements of cooling water of temperature and pure water. The equipment is especially suitable for the need of keeping working under the condition of low temperature, chemical, biological, physical laboratory, medicine and health care, chemical industry, food industry, metallurgical industry, universities and colleges, scientific research, genetic engineering, polymer engineering laboratory equipment necessary.
