Advantages of SUNDI Dynamic Temperature Control System
- Previously unachievable performance
- Intelligent temperature control
- Maximum process stability and reproducibility
- Adop plate heat exchager, Pipeline heating, the fastest heating and cooling rates.
- Large temperature range without fluid change
- Closed system, extend thermal fluid lifetime
- Incredibly compact
- 7-inch, 10-inch color TFT touch screen display
- Comprehensive warning and safety functions
- Use magnetic drive pump, solve the circulation pump leakage
Circulation Pump
High temperature resistant low temperature magnetic drive pump or a leak-free high and low temperature shield-driven pump, reduce the risk of system leakage. At the same time the system has the advantages of low noise and big traffic flow.
Configuration Software (Optional)
- All SUNDI-series dynamic temperature control systems can be connected to a computer. You can install and record the display screen on the computer through the configuration software.
- Communication distance is less than 200m
- Easily set temperature
- real-time control screen
- Curve record temperature control process
- Program selection
- Alarm record
Customer Cases

Structure and Principle of Dynamic Temperature Control System:
Ultra high temperature cooling technology can directly cool from a high temperature of 300℃(because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of - 80℃ ~ 190℃, - 70℃ ~ 220℃, - 88℃ ~ 170℃, - 55℃ ~ 250℃ and - 30℃ ~ 300℃ can be realized without pressurization.
