-45℃ to +250℃ Refrigerated Heating Circulator

Refrigerated heating circulator is a laboratory instrument with dual functions of heating and cooling. The refrigerated heating circulator adopts a number of proprietary technologies and has high temperature control accuracy. It is mainly used in biological, chemical and other fields (such as rotary evaporators, reaction kettles, fermentation tanks, calorimeters and other instruments and equipment). This instrument is highly automated and can automatically heat or cool according to set needs. The refrigerated heating circulator can realize temperature control, has universal heating and cooling functions, and can meet the needs of various biochemical experiments. It has beautiful appearance, compact size, reasonable structure, and reasonable configuration of various internal components and external accessories. Therefore, this equipment is easy to operate, has good heat dissipation, efficient cooling, and quiet operation.

Features of refrigerated heating circulator

1. The ergonomically designed heating and refrigeration circulator operating panel is extremely comfortable, convenient and durable to operate;

2. High temperature control accuracy and wide temperature range;

3. Selected high-quality accessories, carefully crafted, stable in performance, safe and reliable;

4. The insulation and insulation structure are reasonably designed to achieve high-temperature refrigeration;

5. Use a fully closed circulation system to ensure that no oil mist is generated at high temperatures;

6. High-precision intelligent control system: The intelligent control system adopts self-tuning PID algorithm, which can be applied to various environments and equipment, and has high temperature control accuracy. The device has a temperature correction function, which makes temperature measurement more accurate than ordinary thermostats;

7. Rich interfaces, you can connect to PC through RS232, RS485 interface or aviation plug, modify and control the parameters of the equipment through the computer, and also transmit various parameters of the equipment operation to the computer in a timely manner. The equipment can be configured with an aviation socket to provide water level, water flow and alarm signals through the socket. These signals are all standard relay node types, which can easily exchange information with online supporting equipment. Through online signals, user equipment is protected and the safety of equipment operation is effectively improved.
