The refrigeration and heating equipment is commonly referred to as the TCU system in the chemical industry. This mainly utilizes existing energy sources (steam, circulating water, and chilled water), integrating primary energy into a single flow system or secondary circuit for accurate temperature control of process equipment. The medium of the integrated cold and hot temperature control machine continuously conducts heat to the jacket of the reaction kettle, instead of directly controlling the temperature of the reaction kettle through steam, cooling water, and ultra-low temperature medium. The refrigeration and heating equipment automatically adjusts the temperature required for the overall reaction through big data calculation.

In terms of reliability testing for automotive grade chips, Shanghai Putaike High and Low Temperature Testing Machine has unique advantages that are different from traditional high and low temperature impact testing chambers: fast temperature change rate, fast temperature rise/fall of 18 ℃ per second, real-time monitoring of the actual temperature of the tested component, and the temperature of the impact airflow can be adjusted at any time. It can perform high and low temperature impact on a single IC among many components on the PCB circuit board separately, without affecting other peripheral components

It mainly consists of heating circulation system, cooling system, control system, box, etc. The heating cycle system consists of a circulation pump, an electric heater, an expansion vessel, an exhaust valve, a one-way valve, a thermal resistor, and a circulation pipeline. The cooling system consists of oil-water heat exchangers, oil-oil heat exchangers (some equipment), cooling water solenoid valves, high-temperature solenoid valves, etc. The control system adopts PID control technology, high-definition touch screen display, and is equipped with multiple protection functions to ensure the safe operation of the equipment. By heating and cooling the unit itself, the heat carrying fluid is transported to the outside world to meet the requirements of the process conditions.

The reaction kettle temperature control system can be used to control the temperature of chemical synthesis reactions. By precise temperature control, the reaction rate, selectivity, and product purity can be adjusted to improve the efficiency and yield of the synthesis reaction. Putek's reaction kettle temperature control system is suitable for dynamic constant temperature control of cold and heat sources such as jacket reaction kettles, microchannel reactors, reaction devices, combined chemistry, as well as low-temperature distillation, distillation, extraction and other equipment in the pharmaceutical industry.
