Brief Introduction

DLSBThe series type low-temperature coolant circulation pump is a low-temperature liquid circulation equipment that adopts mechanical refrigeration. It has the function of providing low-temperature liquid and low-temperature water bath. Combining rotary evaporators, vacuum freeze-drying ovens, circulating water multi-purpose vacuum pumps, magnetic stirrers, and other instruments for multifunctional low-temperature chemical reaction operations and drug storage.

A large low-temperature coolant circulation pump with constant current, constant pressure, and circulating liquid can meet the needs of electron microscopes, electron probes, and ultra-high vacuum sputtering instrumentsXThe cooling needs of valuable instruments and equipment such as optical machines, lasers, accelerators, etc. For large-scale equipment such as high-purity metals, rare substance purification, environmental experiments, magnetron sputtering, and vacuum coating, we can provide cooling water that meets the dual requirements of temperature and pure water quality. This equipment is particularly suitable for chemical, biological, and physical laboratories that require maintenance at low and normal temperatures. It is used in laboratories such as medicine and health, chemical industry, food industry, metallurgical industry, colleges and universities, scientific research, genetic engineering, and polymer engineeringEquipment.

(1)Original fully enclosed compressor units and circulating water pumps from internationally renowned manufacturers, with advanced performance and reliable quality;

2)Special relays, protectors, capacitors, and refrigeration components for refrigeration units are imported high-quality original components;
3)Digital temperature display, microcomputer temperature control, easy to operate and eye-catching;
4)The circulation system adopts anti-corrosion materials, which have the functions of rust prevention, corrosion prevention, and low-temperature liquid pollution prevention;
5)It can prevent scaling and pollution of circulating water in situations where energy is saved, water sources are scarce, water quality and pressure are poor; Under adverse working conditions in high-temperature areas, it can effectively protect the normal operation of large precision instruments and equipment.
