| Room temperature ~150°C | 1. The working medium works in a closed environment without loss, odor, environmental protection and energy saving;
2. No need to add or replace the working medium for long-term work;
3. No mechanical stirring, no mechanical friction, safe and reliable, reducing the uniformity of temperature field caused by mechanical failure;
4. The temperature field range is wide and the adaptability is wide;
5. No oil smoke, will not cause health damage to the operator;
6. Energy saving and consumption reduction, under constant temperature conditions, the energy consumption is only a few hundred watts:
7. The temperature rise and fall speed is fast, saving time;
8. The main body is made of stainless steel to ensure long-term use without corrosion and deformation;
9. Multiple protections, with over-temperature and over-pressure electrical protection, higher safety;
10. Imported high-performance intelligent power regulator is adopted, which has the advantages of high temperature control accuracy, small temperature overshoot and small temperature fluctuation. | The water tank needs an agitator to ensure the uniformity of the temperature field; the slot is open, and the working medium will be lost after a period of use. The liquid level of the working medium must be checked during operation to ensure that the liquid level reaches a certain requirement, and the working medium must be replaced with a new working medium after a period of use; water has a large heat capacity ratio, and the temperature rises and falls slowly, resulting in high energy consumption. |
| 150°C~300°C | The oil tank needs a stirrer to ensure the uniformity of the temperature field; the slot is open, and the working medium will be lost after a period of use. The liquid level of the working medium must be checked during operation to ensure that the liquid level reaches a certain requirement, and the working medium must be replaced with a new working medium after a period of use, which has a high cost of use; when the oil is heated to above 200℃, there will be oil smoke, and exhaust facilities are required. When the temperature rises to 300℃, the oil smoke is very large, which is harmful to human health; the temperature rises and drops slowly, and the energy consumption is high. |
| 200°C~400°C | When the temperature is above 300℃, a salt furnace or salt tank is used. The tank needs a stirrer to ensure the uniformity of the temperature field. The slot is open, and the liquid level of the working medium must be checked during operation to ensure the liquid level. The working medium needs to be replaced after a period of use. When the temperature is increased, there is smoke, which is harmful to human health. Smoke exhaust facilities are required. The tank heats up very slowly, and the salt in the entire tank must be used up before it can work, which consumes a lot of energy. Sometimes when the salt furnace (salt tank) is heated, the working medium explodes, and the safety factor is low. |
