Low temperature liquid bath is a high-precision constant temperature source with built-in refrigeration, which can be used for constant temperature freezing experiments in the water tank inside the machine, or connected to other equipment through hoses as a matching constant temperature source. Widely applicable to research departments such as petroleum, chemical, electronic instruments, physics, chemistry, biopharmaceuticals, medicine and health, life sciences, light industry and food, biotechnology, beer quality testing, artificial board manufacturing physical property testing and chemical analysis, higher education institutions, enterprise quality inspection and production departments. The refrigeration power output of each level can meet the high-precision cyclic cooling of large industrial equipment to small experimental analysis instruments. Users can provide a cold controlled temperature uniform and constant field source when working, which can be used for constant temperature testing or testing of test samples or produced products, or as a direct refrigeration source.

Product Features

1. Adopting single compressor natural cascade refrigeration technology, the result is simple and stable operation, and it has multiple protection devices for overheating and overcurrent.

2. Easy to operate: Simply connect the power supply to use

3. Efficient: It only takes about 30 minutes for the refrigerant to reach the target temperature from room temperature.

4. Temperature range of refrigerant: -35 ℃~-125 ℃ adjustable

5. Low cost of use: Simply connect the power supply, with an average of less than 5 kWh per hour, no other vulnerable parts or consumables, safe and reliable.

6. The circulation pump can draw out the constant temperature liquid in the tank and establish a second constant temperature field.

7. The cold liquid inside the tank can be introduced externally, and the experimental container outside the cooling machine can also be used for low-temperature and constant temperature experiments directly inside the tank

8. Adopting PLC automatic control system with temperature digital display.

9. The inner liner and countertop are both made of 304 stainless steel, which is clean, hygienic, beautiful, and corrosion-resistant.

Precautions for use

1. Add liquid medium into the low-temperature constant temperature bath before use. The liquid level of the medium should be about 40mm lower than the worktable, otherwise the heater will be damaged when powered on;

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

When the working temperature is between 15-7 ℃, water is generally used as the refrigerant medium;

When the working temperature is between 5-25 ℃, a 35% ethylene glycol aqueous solution can be used as the refrigerant medium;

When the working temperature is between -30 ℃ and -100 ℃, alcohols are generally used as the refrigerant medium

When the working temperature is between -100 ℃ and -125 ℃, synthetic alcohols are generally selected as the refrigerant medium

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
