WORKING PRINCIPLE

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃[because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.

Color Screen Control

1. Displays all the kind of process control temperatures.
2. Shows the liquid level of the heat conducting medium in the expansion vessel.
3. Shows indication for refrigeration system working.
4. Shows indication for heater working.
5. Shows indication for circulation pump working.
6. Displays the temp. control ( materials temp. control pattern, heat conducting medium temp. control ).
7. The temp. upper limit, lower limit control can be set.
8. The temp. difference between jacket & reactor material can be set.
9. Shows the alarm to add the liquid when it is empty.
10. The refrigeration compressor can be set to operate manuallyor automatically.

APPLICATIONS

New materials | Special gas production temperature control

New materials, as newly developed or developing structural materials with excellent performance and functional materials with special properties, have extremely high requirements for temperature control in their research and development and production processes. The production of special gases, such as oxygen, nitrogen, argon and other industrial gases, also requires precise temperature control to ensure product quality and production efficiency.

API | intermediate production temp control solution

In the production process of raw materials, many chemical reactions need to be carried out within a specific temperature range. For example, in the production of antibiotics, even a slight change in temperature may affect the growth rate of the bacteria and the activity of the product. Therefore, the use of high-precision temperature control systems, such as high and low temperature all-in-one machines or temperature control reactor oil temperature machines, has become the key to ensuring smooth production. These devices have built-in high-precision temperature control systems and use PID temperature control technology to achieve a temperature control accuracy of ±0.1°C, ensuring that each chemical reaction can be carried out at the appropriate temperature.

Distillation concentration temperature control solution

The basic principle of distillation and concentration is to utilize the difference in volatility of the components in the mixture, vaporize the volatile components under heating conditions, and then collect them through condensation to achieve the purpose of separation and concentration. In this complex and delicate process, temperature control technology is not only the key to ensure smooth operation, but also an important factor affecting product quality and efficiency.

Customer Recommendation

Sometimes it's not about us praising how good we are, but rather the feedback from real customers.

I bought a chiller from Lneya for my company's chemical project. From the information on their cooling power, the cooling speed is super fast, which means that it can cool down from a very high temperature in a short time. I really like the chiller from this company.

--Lillia

Testimonial

I have a large stainless steel reactor with very strict temperature control, pressure and power requirements. Lenya was very professional from the initial purchase to the installation. I would highly recommend this company.
