High/Low Temperature Circulating Unit CNGD-0300-30 - Intelligent Temperature Control, Fast CoolingThe temperature adjustment speed is typically quite fast, mainly due to its highly integrated active temperature control design. The device's powerful compression refrigeration unit and high-power electric heater can quickly generate cold and heat, which are then exchanged with the heat-conductive medium through an efficient heat exchanger. At the same time, the forced circulation pump rapidly pumps the temperature-adjusted medium into the external jacket or reactor of the user's equipment, achieving active and efficient heating or cooling, thus far exceeding the temperature change rate of traditional static equipment like ovens and water baths.

However, the specific adjustment speed is not fixed and is constrained by multiple key factors. This includes the cooling and heating power of the equipment itself, the thermal capacity of the entire system to be temperature-controlled (such as the size of the reactor and the amount of material), the set temperature difference range (e.g., rising from -80℃ to 100℃ is significantly slower than from 20℃ to 30℃), and the type and capacity of the heat-conducting medium used by the equipment. Therefore, in practical applications, the cooling or heating rate can vary significantly based on different process requirements.

CNGD-0300-30 High and Low Temperature Cycle Unit, Smart Temperature Control and Quick CoolingKey Features:

Self-developed temperature control technology with high-standard PT100 and all imported electronic components.

2. High-efficiency fully enclosed refrigeration with fast cooling speed, featuring multiple protections such as overheating and overcurrent.

3. Smart software temperature control with PID, which can automatically tune parameters according to different mediums.

4. Extra-large LCD screen with bilingual (Chinese-English) display, clear data, attractive appearance, capable of showing the difference between displayed and actual temperature, with a temperature resolution up to 0.01℃.

5. The body shell is coated with a mirror-like anti-aging static spray paint technology, and the inner lining countertop is made of 304 stainless steel, ensuring cleanliness, hygiene, beauty, and resistance to corrosion.

6. Features over-temperature protection and alarm with a customizable over-temperature alarm temperature; the load can be automatically disconnected when over-temperature occurs.

7. The equipment features an internal and external circulation system. The internal circulation ensures even and stable temperature, while the external circulation pump outputs a constant-temperature fluid to establish a second constant-temperature field outside the machine. It can also serve as a cooling source to cool external experimental containers.

8. Pressing the "Power" button will disable all functions of the instrument, yet it still displays the natural rise and fall process of the槽内 temperature.
