LDJ-6F Heating Refrigeration Temperature Control system

  • LDJ-6F
Product Description
Only need to connect the equipment with the liquid inlet and outlet of reactor device, from the top of the equipment liquid inlet add in the heat transfer medium, turn on add liquid button can easily remove the air in the system, set the temperature requirements, the system can run automatically. The heat transfer medium in a closed system, with expansion container, the liquid in the expansion container not participate in the circulation, either high or low temperature, expansion tank temperature is from room temperature to 50 ℃, can reduce the risk of heat absorption of moisture and volatile in the operation. In case of no changing the heat transfer medium, can be covered -90℃ to 200/300℃ temperature control range.

Product Advantages & Feature

◎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 fall

◎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 callback

◎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.

◎5.3 inch color touching screen display and input; control system provide: USB interface, RS232 interface, PT100 input interface, fault alarm output interface

◎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.

◎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;

◎Refrigeration unit using France TECUMSEH compressor, high temperature magnetic drive circulation pump, stable performance, reliable quality;

◎It has the function of self-diagnosis; Refrigerator overload protection; high pressure switch, overload relay and thermalprotection device etc. multiple security functions

◎High lift design to meet long distance transmission medium

◎Using a variety of environmentally friendly refrigerants to meet environmental requirements.

Product Applications

The heating refrigerated circulators are widely used in chemical industries , pharmaceutical plants , biological engineering , kilo labs , pilot plant and other related areas . They can control the temperature of mixing tank , jacketed glass ( metal ) reactors, thermal test platform and etc .
