Low Temperature Constant Temperature Circulator CNHX-010

Low-temperature constant-temperature circulators are used in research departments, universities, and corporate quality inspection and production departments in industries such as oil, chemicals, electronic instruments, physical chemistry, bioengineering, medical hygiene, life sciences, light industry, food, physical property testing, and chemical analysis. They provide users with a controlled cold and hot environment with uniform and constant temperature during work, allowing for constant temperature tests or measurements on experimental or production samples. They can also serve as direct heating or cooling sources.

Key Features:

1. Suitable for use with rotary evaporators, fermentation tanks, Abbe refractometers, electron microscopes, low-temperature chemical reactors, transparent glass reactors, and biological Z reactors, etc., for experimental equipment accessories.

2. Internal/External circulation pump system, the internal circulation ensures uniform and constant temperature of the instrument; the external circulation pump outputs 5 liters/minute to 18 liters/minute of low-temperature constant-temperature liquid, with a head of 4.0 meters.

3. The work slot container can accommodate various containers holding biochemical reagents or test samples, allowing for direct low-temperature testing or analysis, achieving multi-functional use with one machine.

4. High-efficiency fully enclosed refrigeration system with air-cooled compressor, low noise, and rapid cooling.

5. Large screen LCD display, precise temperature setting, easy and quick operation.

6. Multiple resolution options available: 0.1℃, 0.01℃, and 0.001℃.

7. Features temperature measurement value deviation correction function.

8. Over-temperature protection, sensor abnormality protection, high-temperature alarm, adjustable temperature setting, cooling system overheating, overcurrent automatic protection.

Why is the refrigeration effect of the low-temperature constant-temperature water bath decreasing?

1. The condenser of the low-temperature恒温槽 is dirty: It's the area where the low-temperature恒温槽 can draw in air after operation, with many aluminum foil heat dissipating sheets. Check if they are dirty, and if so, clean them by blowing with nitrogen.
2. Is it too close to the wall? If so, move it a bit further away. The ventilation space is insufficient, and the air cannot circulate properly. If the heat cannot dissipate, it won't be possible to cool down.
3. Is the medium low in concentration? After a period of use, condensate from the air will enter the medium, becoming thick at low temperatures and impeding heat transfer, resulting in a decrease in temperature. If the medium is too thick at low temperatures, it cannot flow normally or may freeze, in which case a change of medium is required.
After using the low-temperature tank for over a year, the refrigeration speed seems to have slowed down, becoming more noticeable as the temperature rises?

Regular maintenance of a low-temperature恒温槽 is crucial and cannot be overlooked. Many issues that appear to be malfunctions are actually caused by a lack of regular maintenance. Both the electrical power of the water circulation and the heat carried away by the refrigerant from the load need to be dissipated through the radiator at the front ventilation cover. If the front ventilation cover is filled with dust and fluff, it hinders the dissipation of these heat, significantly reducing the refrigeration effect. Generally, a decrease in refrigeration capacity under normal operating conditions is due to poor ventilation and heat dissipation or excessively high ambient temperatures.
