Low temperature cooling circulator play a crucial role in the manufacturing process of chemical materials. These devices improve product quality, efficiency, and safety by providing precise and stable low-temperature environments to ensure that chemical reactions occur under optimal conditions.

The following are the specific applications and importance of low-temperature cooling cycle machines in chemical material manufacturing processes:

1. Temperature sensitive reactions control many chemical reactions that are highly sensitive to temperature, especially in the synthesis of polymer materials, pharmaceutical intermediates, and other fine chemicals. Low temperature can suppress the occurrence of side reactions, ensuring the selectivity and yield of the main reaction pathway.

For example:

Aggregation reaction: Low temperature can reduce side reactions and improve the molecular weight distribution of polymers.
Enzyme catalyzed reaction: Low temperature can maintain enzyme activity and improve catalytic efficiency.

2.Thermistor materials protect certain chemical materials from easily decomposing or deteriorating at high temperatures. Low temperature circulating cooling equipment can provide a safe working environment and prevent materials from being damaged during processing.

For example:
Bioactive substances, such as enzymes, proteins, etc., are prone to deactivation or denaturation at high temperatures.
Volatile solvents: Low temperature can reduce solvent evaporation, avoiding losses and safety hazards.

3.Optimizing the crystallization process at low temperatures helps promote the formation of crystals and improve their quality and purity.

For example:
Drug crystallization: Low temperature can improve the purity and consistency of crystals, which is beneficial for subsequent purification and formulation.
Metals and alloys: Low temperature treatment can improve the microstructure of materials and enhance their mechanical properties.

4.Reaction rate regulation: By precisely controlling the temperature, the rate of chemical reactions can be adjusted to ensure that the reaction is completed within a controllable time.

For example:
Exothermic reaction: Low temperature can slow down the reaction rate, prevent the reaction from getting out of control, and ensure safe operation.
Heat absorption reaction: Low temperature can provide the required heat absorption conditions to ensure the smooth progress of the reaction.

5.Product quality improvement: Low temperature cooling cycle machines can ensure that chemical reactions occur under constant and precise temperature conditions, thereby improving product quality and batch repeatability.

For example:
Pharmaceutical industry: Low temperature can ensure consistent reaction conditions during drug synthesis, improving the purity and stability of drugs.
Fine chemicals: Low temperature can ensure selectivity and yield in the synthesis process, improving the quality of the final product.

6.Energy saving and environmentally friendly low-temperature cooling cycle machines usually have efficient energy recovery systems that can recover waste heat during the cooling process for use in other process steps, achieving effective energy utilization.

In addition, low temperatures can reduce the emission of volatile organic compounds (VOCs) and lower environmental pollution.

7.Equipment protection and extended lifespan. High temperatures can accelerate the aging of internal components and shorten the service life of equipment.

Low temperature cooling circulator can effectively remove the heat generated by equipment, keep the equipment within a suitable working temperature range, and extend the service life of the equipment.

• Aggregation reaction: In processes such as free radical polymerization, ion polymerization, and ring opening polymerization, low temperature can reduce side reactions and improve the molecular weight distribution and purity of the polymer.
• Drug synthesis: During the synthesis of drug intermediates and active ingredients, low temperature can ensure the selectivity and yield of the reaction, improve the purity and stability of the drug.
• Materials Science: In the process of preparing nanomaterials, composite materials, etc., low temperature can improve the performance and consistency of materials, such as size, morphology, and mechanical properties.
• Biotechnology: In processes such as cell culture and protein purification, low temperature can maintain the activity and stability of biological samples, ensuring the accuracy and reproducibility of experimental results.

Main features of LNEYA low-temperature cooling chillers

• Wide temperature range: covering the needs of most chemical material manufacturing.
• High precision temperature control: Using PID controller or other advanced temperature control technology to achieve high-precision temperature control, the control accuracy is usually within ± 0.1 ° C or less.
• Rapid heating and cooling ability:
  Heating: Heating the heat transfer medium (such as water or ethylene glycol solution) through an electric heater.
  Cooling: The heat transfer medium is cooled to the desired temperature through a compressor refrigeration or cooling water circulation system.
• Circulating pump: Circulating the heat transfer medium between the cooling equipment and the reaction kettle to ensure uniform temperature distribution, with a flow rate typically ranging from a few liters per minute to several tens of liters per minute.
• Safety protection measures:
• Over temperature protection: When the temperature exceeds the set value, the power will be automatically cut off.
  Overvoltage protection: prevents excessive system pressure.
  Leak detection: Check if the system has any leaks.
  Emergency stop button: Quickly stop system operation in case of emergency.
• User interface:
