Product Description

DLSB-40 series low-temperature cooling liquid CIRCULATING PUMP for biology physics chemical laboratory

Production Description

DLSB-40 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 40L, 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-40 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-40 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).

Our company's main Glass Reactor, Rotary Evaporator Rotovap, Nutsche Filter, Lab Heating Cooling Machine, Short Path Distillation, Hydrothermal synthesis reactor.

Product Characteristics

1. Air-cooled fully enclosed compressor for refrigeration, the microcomputer intelligently controls the refrigeration system to automatically start, and the refrigeration system has multiple protection devices such as delay, overheating, and overcurrent.
2. The refrigeration unit, special circuit breaker, protector and capacitor have reached the international advanced level
3.The circulating pump can output the cooling liquid in the tank to cool or thermostat the experiment container outside the machine or establish a second constant temperature field.
4.The circulation system is made of stainless steel, which has the functions of anti-corrosion, anti-rust, and anti-low temperature liquid pollution.
5. With computer software lock function, can lock the setting value of each parameter of the system, non-professionals can not change the set parameters at will.
6.All operations are completed by pressing the touch software on the microcomputer intelligent controller, and the operation is simple and intuitive.
7.The product is easy to use and can work continuously.
8.Especially suitable for equipment requiring high-power cooling capacity.
