High precision integrated cold and hot machine

(-120 ℃~+350 ℃) (accuracy ± 0.1 ℃)

The high and low temperature all-in-one machine does not require the replacement of thermal conductive media, and can directly heat up and cool down. It uses a fully enclosed system, high temperature without oil mist, and no odor. Low temperature does not absorb air moisture. Suitable for rapid heating, cooling, and dynamic constant temperature control of cold and heat sources in equipment such as chemical and pharmaceutical industries, microchannel reactors, coils, jacketed reactors, low-temperature distillation, and extraction. It can also be used for thermal management of automotive components TCU、 Liquid cooling testing for semiconductor equipment, electronic water pumps, power batteries, motors, and controllers, with optional multi-channel integrated design for simultaneous liquid cooling testing of multiple objects.

1、 Characteristics of the dynamic temperature control system for high and low temperature integrated refrigeration/heating:

1. Stable and efficient: The use of a single compressor self stacking system has a simple structure, stable system, and low failure rate.

2. Easy to operate: Siemens PLC programmable controller, with clear interface functions, can start fully automatic operation with one click. Real time display of equipment operation status makes maintenance and use more intuitive and convenient. Configure RS485 communication interface and Modbus RTU protocol.

3. Dynamic temperature control technology: The temperature measurement points at the inlet and outlet of the liquid and the material will transmit real-time temperature information. When the temperature difference is large, the temperature control system will immediately transmit heat release and absorption control signals to accurately control the temperature of the heat transfer medium within ± 0.1 ℃

4. Fully enclosed system: Only thermal conductivity is involved in the circulation expansion tank, and the temperature is always maintained at room temperature of 25 ℃ to avoid problems caused by air entering the circulation system. Pipeline type circulation loop. Fast temperature control response.

5. Wide temperature range: Using a thermal conductive medium for temperature control without the need for replacement, it is easy to achieve precise temperature control over a wide temperature range of -120 ℃~350 ℃.

A wide range system temperature control of -80~+200 ℃ can be achieved using a single thermal conductive medium. Single cooling medium can achieve -120 ℃, single heating medium can achieve+350 ℃.

6. Safety protection function: It has self diagnostic function, multiple alarm protection, circulation pump failure, compressor overheating, overload, phase sequence, pressure and other protection functions.

7. High temperature cooling technology: High temperature direct cooling can directly perform refrigeration and cooling operations during high-temperature exothermic reactions. For example, at a high temperature of 350 ℃, the compressor can be directly started for cooling without changing the medium, achieving rapid cooling

8. Easy installation: The entire machine has been assembled and adjusted, and upon arrival at the user's site, simply connect the power supply, cooling water, heat exchange pipes, and add heat exchange medium to start up and operate.

9. Our company can provide exclusive temperature control solutions according to user needs (low temperature -150 ℃, high temperature+350 ℃, constant temperature ± 0.1 ℃). In addition to temperature customization according to needs, explosion-proof electrical devices can also be installed for the whole machine. The unit's heat dissipation method can choose single air cooling, water cooling, air cooling+water cooling auxiliary. There is also a PLC control system that can independently control the upper and lower limits of temperature, and set the temperature difference between the control jacket and the material separately. It can display a menu navigation bar that allows for easy emptying and liquid addition, manual activation of intelligent compressors, and automatic activation of self powered compressors. Customers can choose and customize models based on their own needs.
