-45℃~250℃
In comparison to other thermal control systems, Dynamic Temperature Control systems differ sometimes considerably in their thermodynamic characteristics. In practice, Dynamic Temperature Control systems offer definite advantages in your work: noticeably shorter heating and cooling times, better stability and reproducibility through the entire process chain, greater safety for expensive glass reactors and the contained substances, together with the simple and easy operation.

Advantages and functions of temperature control system of refrigeration

Temperature range from 120 to 350, performance superior, unique, high - precision, intelligent temperature control.

7-inch and 10-inch color TFT touch screen graphics display, use magnetic drive pump, no re-seal leakage problem.
Full airtight system, extended thermal conductivity liquid life, very wide temperature range, no need to change liquid media.
Ultra-high temperature cooling technology can be cooled directly from 300 degrees of high temperature.
The principle and the function has many advantages to using staff: because only expansion of cavity in the body heat conduction medium contact with oxygen in the air (and expansion tank temperature at room temperature to 60 degrees), can achieve lower heat conduction medium absorbed by oxidation and the risk of air moisture.
No heat conduction medium evaporates at high temperature, and it can be achieved -80 ~ 190 degrees, -70 ~ 220 degrees, -88 ~ 170 degrees, -55 ~ 250 degrees, -30 ~ 300 degree continuous temperature control without pressurization.


Adopt full closed pipe design, adopt high-efficiency plate heat exchanger, reducing the demand for heat conduction liquid, improve the heat utilization rate of the system, reach the rapid lifting temperature.Thermal conductive medium in a closed system, with a container, expand the heat-conducting medium not participate in circulation in the container, whether high or low temperatures, expansion tank temperature to room temperature to 60 degrees, can reduce the heat conduction medium in running the risk of absorbing the moisture and volatile.

Operating Principle of Industrial Air Chillers

Industrial air cooler is a heat exchanger which USES air to cool the hot fluid. The hot fluid in the tube is heated through the exchange of heat between the tube wall, the fin and the outside air, which is usually supplied by the ventilator. Our Industrial Air Chillers SUNDI -45℃ ~ 250℃ can be applied to cooling and condensation such as

condensation of the top steam of oil refining and petrochemical industry, reflux oil, cooling of tower bottom oil, the cooling of various reaction products, cooling of circulating gas and condensing of steam turbine exhaust. Its working pressure can reach 69 mpa. However, the power consumption, noise, and floor area are large, and the cooling effect is greatly affected by climate change.

In order to avoid the heat medium affect the performance of medium because of long-term overheating, and to facilitate the storage or transportation, and to condense and distillate, we need to exchange heat of the medium. Usually, heat exchange equipment should be used to achieve the purpose of exporting, exchanging and cooling. When air is used as one kind of medium, this equipment is called air cooler.

Air cooler is widely used in petroleum, chemical industry, metallurgy and other industries as well as in the process industry.

Due to the low heat transfer coefficient of air and the high heat transfer coefficient of tube heat medium, their difference reaches several number grades, so we often use high fin in air cooler, close distance of double metal finned tube as the main heat transfer element. Heat through efficient heat exchange tube of the heat transfer medium is passed to the air which after accepting the heat temperature rises, at this time, the heat medium temperature drops, the air temperature rises, the hot air is directly emitted to the atmosphere to achieve the goal of decreasing the heat medium temperature.
