GDSZ-3035 High and Low Temperature Circulation Device, Ordinary, 7.3KW, Gongyi Yuhua Instrument Co., Ltd (CAT#: STEM-GLE-0536-YJL)

GDSZ-3035 High and Low Temperature Circulation Device, Ordinary, 7.3KW, model GDSZ-3035 Ordinary is manufactured by Gongyi Yuhua Instrument Co., Ltd. The liquid circulation of the whole system of the high and low temperature series devices is closed, the system has an expansion vessel, the expansion vessel and the liquid circulation system are adiabatic, not involved in the liquid circulation, but only mechanically connected. The medium in the expansion vessel remains at room temperature regardless of the temperature of the circulating liquid. Since the entire liquid cycle is a closed system, there is no absorption of water vapor at low temperature, and no oil mist is generated at high temperature. The company can provide heat transfer oil with a wide range of operating temperatures, so the same machine and the same heat transfer medium can achieve temperature control from -90°C to 200°C.

● There is no tank for internal circulation, the volume of internal circulation is small (the volume of internal circulation in most equipment is only 6-10L), the effective power density is large (W/L), the rate of heating and cooling is fast, and the demand for heat transfer oil is also high. smaller.
● The equipment adopts wave-shaped plate heat exchanger, which has large heat exchange area and fast heat exchange speed.
● The whole closed liquid circulation: no oil mist volatilization at high temperature, heat transfer oil will not be oxidized or browned; at low temperature, it will not absorb water vapor in the air, prolong the life of heat transfer oil and low cost.
● Precise control of the temperature of chemical reactions is the first choice for safe control of exothermic reactions.
● The equipment adopts PID intelligent control, which automatically adjusts the power output according to the chemical process technology, precisely controls the temperature of the reaction process, and meets the requirements of the reaction process for temperature changes.
● The specially customized circulating pump can provide the maximum flow rate, generate the minimum pressure and heat, achieve the highest heat exchange efficiency, the minimum system resistance, the minimum pump system heat, and the minimum system energy consumption.
● The standard type adopts PLC control, with a more user-friendly display interface (man-machine interface), which is easy to operate, and can display the set temperature, outlet temperature, and temperature change curve of the kettle during the working process, and realize the programming of the rising and falling temperature sections of the program. .
● For the standard type, the maximum temperature difference between the reactor body and the interlayer can be set according to the safety requirements provided by the reactor manufacturer. If the temperature difference between inside and outside reaches the safety limit value required by the manufacturer, the equipment will automatically stop working and give an alarm to ensure that the reactor will not rupture due to excessive temperature difference.
