What is a chiller?

DLSB series refrigeration pump is also called low temperature cooling water circulating pump. This type of refrigeration pump has a water tank volume of 50L; adopts PT100 temperature sensor, which has a wide measurement range and good pressure resistance; uses difluoromethane (R22) as refrigerant, which has good cooling effect; uses compressor for mechanical refrigeration; The water circulation pump makes the cooled liquid circulate inside and outside through the pipeline, and can provide low temperature liquid and low temperature bath; it can be used with rotary evaporator, vacuum freeze drying oven, water circulation vacuum pump, magnetic stirrer and other equipment to carry out multi-functional chemical reaction.

Product Display

The large size color touch screen can clearly display the real-real temperature change during the process engineering. It is convenient and quick to maintain the equipment with the door and window type opening and closing design. The overhead design of the fan can meet more heat dissipation requirements. It is more accurate to judge the machine faults with the display of quadruple pressure gauges at high and low pressure ends of the compressor

Features of chiller

Imported air-cooled hermetic compressor unit with advanced performance and reliable quality; Special relays, protectors, capacitors, refrigeration components and imported high-quality components for refrigerant units; Digital constant temperature display, microcomputer temperature control, simple and eye-catching operation; Large cooling capacity and fast cooling speed, greatly improving work efficiency; It can effectively protect all kinds of precision equipment and instruments to be used normally under water shortage conditions; The circulation system is made of stainless steel, which has the functions of anti-corrosion, anti-rust and anti-cold liquid pollution; The coolant can be delivered to the place of use at low temperature; The original circulating pump of international famous factory is installed inside; The microcomputer intelligently controls the refrigeration system to open automatically. The refrigeration system has multiple protection devices such as time delay, overheating, and overcurrent.

Application of chiller

DLSB series refrigeration pumps are suitable for chemical, biological and physical laboratories that need to maintain low temperature and normal temperature conditions. It is an essential equipment in the fields of medical and health, chemical industry, food, metallurgy, colleges and universities, scientific research, genetic engineering, polymer engineering and other fields. (The large-capacity low-temperature coolant circulation pump can be customized according to user needs.)


Check whether the inlet and outlet valves of the refrigeration pump are normally opened and whether the pressure is within the normal range. Check whether the power of each device is in the ON position. Ethanol with a refrigerant concentration of ≥97% should be added; Check the power supply: the power of the power supply should be greater than the total power of the instrument, and the power supply must have a good “grounding” device; The equipment should be placed in a dry and ventilated place, and there are no obstacles within 500mm around the instrument; Pay attention to the position of the liquid level in the tank. When the liquid level is too low, the refrigerant medium should be added in time; When the equipment is working, the temperature of the inlet and outlet pipes is high, so be careful not to touch it to prevent frostbite; After use, cut off the power supply; Regularly remove debris from the condenser to avoid the reduction of product use efficiency due to excessive dust;
