Low temperature circulator

  • SUNDI-875
Product Description
High and low temperature cycle device is integrated with low temperature and high temperature instrument device loop device is based on market research and careful development and design of a low temperature cooling liquid circulating pump and the high temperature oil bath pot on the basis of a new series of two machine integration equipment.High and low temperature cycle device is widely used in colleges and universities, environmental protection, biological, medical, scientific research and other fields.Products reasonable structure, easy operation, stability, strong wait for a characteristic, is a kind of adapt to its national conditions, to research the compression time is the ideal product.  
Product Advantages & Features
1. The design of full closed pipeline, adopt high efficiency plate heat exchanger, reducing the demand for heat conduction fluid while providing the system's heat utilization rate, to achieve temperature rapid rise and fall2. The use of feedforward adaptive programmable controller, can accurately control the temperature of the reactor material, and the system in the control process, no overshoot, no callback3. Can store up to write a 120 set of programs, and each program can be written in 100 paragraph, fully guaranteed to meet the temperature requirement in the case of different materials. The user only need to according to the different materials call out procedures, then could achieve accurate temperature control, avoid the process of manual operation, improving the stability of product.4. 5.3 inch color touching screen display and input; control system provide: USB interface, RS232 interface, PT100 input interface, fault alarm output interface5. Temperature process control charts can be displayed in high resolution color touch screen, including oil temperature, set the target value, the reactor material control temperature value, easy to query the whole process control. Using the USB data storage interface, as long as directly insert USB flash disk, the whole process of temperature control, data could record.6. Fully closed design of heat conducting oil circulation pipeline, no oil mist and water absorption, to ensure the safety of the experiment and the life of the conductive fluid;7. Refrigeration unit using France TECUMSEH compressor, high temperature magnetic drive circulation pump, stable performance, reliable quality;8. It has the function of self-diagnosis; Refrigerator overload protection; high pressure switch, overload relay and thermal protection device etc. multiple security functions9. High lift design to meet long distance transmission medium10. Using a variety of environmentally friendly refrigerants to meet environmental requirements.
Product Applications
Applied in chemical reactor , pharmaceutical reactor or biotechnology reactor ; Control mixing tank temperature ;Metal(glass) double layer reactor ; Thermal test platform ; Constant temperature control of material and equipment.
