Fully enclosed high and low temperature circulation device

High and low temperature circulation device
1、 Product Overview

1. The liquid circulation of the entire system of the high and low temperature series device is sealed, and the system is equipped with an expansion container. The expansion container and the liquid circulation system are insulated and do not participate in the liquid circulation, only mechanically connected. Regardless of the temperature of the circulating liquid, the medium in the expansion container always maintains room temperature.
2. As the entire liquid circulation is a closed system, there is no absorption of water vapor at low temperatures and no generation of oil mist at high temperatures. The company can provide thermal oil with a wide range of working temperatures, so the same machine and the same thermal medium can achieve temperature control from -80 ℃ to+200 ℃.

When purchasing instruments, please identify "Gongyi Yuhua Instrument Co., Ltd." as the only company without a branch.

2、 Advantages

1. The temperature control accuracy is generally ± 1 ℃, and external sensors can be connected (the temperature difference accuracy of installing external sensors is generally ± 0.5 ℃).

2. It has a PLC computer module that can be connected to a computer for remote control. It can achieve multi-point continuous temperature control, segmented temperature control, and constant temperature control, and can control multiple high and low temperature devices with one computer. (More convenient to use, greatly improving work efficiency)

3. Equipped with USB interface and data download function. (Data download function, which enables customers to download and store relevant data of tested or reacted materials, providing reference data for experiments)

4. High temperature limit to prevent equipment from losing control. If the set high temperature of the equipment is exceeded, the equipment will automatically power off (to prevent damage caused by high equipment temperature)

5. Power protection [① Power supply has missing items ② Live wire error items ③ Voltage too high or too low (error code E-01 displayed)]

6. Compressor overheat protection (when the compressor reaches its limit, it will stop working and display error code E-02).

7. Water cooling has water flow and low water pressure protection (error code E-03 displayed).

8. Sensor protection (displaying error code E-04).

9. All compressors are imported from France and Denmark.

Note: (1)High and low temperature circulation deviceConnect the oil pipe to the reaction vessel, which should not exceed 4 meters (2 meters each for the inlet and outlet oil pipes). If the oil pipe exceeds 4 meters, it is advisable to cause the glass of the reaction vessel to break.

(2) The rate of temperature rise and fall is influenced by the surrounding environment. (Generally, the high temperature range of the environment is 30 ℃)

(3) In areas with relatively humid environments in the south (humidity>50%), explosion-proof type should be used.

（4）High and low temperature circulation deviceThe oil connections of the reactor and the oil circuit are both made using a "low inlet, high outlet" approach.
