High-precision cryogenic circulating pump, cryogenic circulating pump bath, ultra-low temperature circulating bath introduction:

Cryogenic coolant circulation pump, high-precision low-temperature constant temperature tank, is a mechanical, single-compressor self-cascading refrigeration technology of low-temperature liquid circulation equipment. It can meet the needs of -40°C.-60°C.-80°C.-100°C.-120°C.-140°C low temperature zone

The product is diversified and can be adapted according to customer needs (temperature, cooling capacity. Equipment size, function) tailor-made: cryogenic coolant circulation pump; Large cooling capacity and fast cooling speed, which greatly improves work efficiency; The flow rate of the circulating pump of this machine can be adjusted or customized, which greatly meets the actual needs of different users; All models of this machine can be reasonably matched between low temperature and refrigeration capacity, low temperature and container capacity according to user requirements

The cryogenic liquid bath is a high-precision constant temperature source with its own refrigeration, which can be used as a constant temperature source for constant temperature freezing experiments in the tank in the machine, or connected to other equipment through a hose. Widely used in petroleum, chemical, electronic instrumentation, physics, chemistry, biopharmaceutical, medicine and health, life sciences, light industry food, biotechnology, beer quality test, wood-based panel manufacturing physical property testing and chemical analysis and other research departments, colleges and universities, enterprise quality inspection and production departments, each gear of refrigeration power output can meet from large industrial equipment to small experimental analysis instruments of high-precision circulation cooling, users work to provide a cold controlled temperature uniform and constant field source, Constant temperature tests or tests on test samples or produced products can also be used as direct refrigeration cooling sources.

Precautions for use

1. Add liquid medium to the tank before using the low-temperature constant temperature tank, the liquid level of the medium should be about 40mm lower than the workbench, otherwise the heater will be damaged when the power is applied;

2. The selection of refrigerant medium in the low-temperature constant temperature tank should comply with the following principles:

When the working temperature is 15~7 °C, the refrigerant medium is generally water;

When the working temperature is 5~-25 °C, the refrigerant medium can choose 35% ethylene glycol aqueous solution;

When the working temperature is -30 °C ~ -100 °C, the refrigerant medium is generally selected alcohol

When the working temperature is -100 °C ~ -125 °C, the refrigerant medium is generally selected as synthetic alcohol

3. Power supply: 220V-380v ?50Hz, the power supply power should be greater than the total power of the equipment, and the power supply must have a good "grounding" device

4. Avoid acid and alkali substances entering the tank to corrode the coil and inner tank.

5. The instrument should be placed in a dry and ventilated place, and there is no obstruction within 300mm around the instrument;
