Performance description of recirculating chiller for bioreactor

The recirculating chiller is suitable for the high and low temperature reaction of various stainless steel, enamel, titanium alloy reactors, emulsifiers, injection molding machines, mixing vessels and various bioreactors. Other bioreactors in different industries are special recirculating chillers. , Wuxi Guanya LNEYA adopts a fully enclosed pipeline design, which can achieve higher efficiency in terms of operating effects.

1. Fully enclosed system

During the operation of the special recirculating chiller for bioreactor, only the heat transfer medium participates in the circulation, and the temperature of the expansion tank is always maintained at room temperature 60, which avoids the problems caused by the air entering the circulation system.

2. High temperature cooling

The compressor can be directly used for refrigeration at high temperatures (using the single-machine self-cascade refrigeration technology), and it can be used for high-temperature exothermic reactions, such as 200 , without changing the medium, only the compressor can control the temperature and take away excess heat. .

3. Wide temperature range

The special recirculating chiller for bioreactors can achieve system temperature control in a wide range of -120~300 with a single heat transfer medium. However, a single compressor refrigeration technology can reach a low -150°C, and is smaller in size and easier to lift.

4. Dynamic temperature control technology

The temperature measurement points at the liquid inlet and outlet and the material will transmit temperature information in real time. When the temperature difference is large, the control system will immediately issue an exothermic and endothermic reaction to control the temperature of the heat transfer medium within ±0.3°C.

5. Pipeline circulation system

Pipeline heaters and plate heat exchangers increase the power density ratio, reduce the amount of heat transfer medium used, and improve the response speed of the system's temperature control.

6. Heating protection

After the control protection of the controller body fails, if the temperature exceeds the temperature value set by the deviation protector in the system, the power supply of the solid state relay will be cut off, and the independent temperature limiter will play its role after the protector fails. With this triple protection, there will be no high temperature overshoot.

The quality of equipment manufactured by different recirculating chiller manufacturers is different, and everyone needs to be aware of this.
