Overview
NELE DC-5020-II high and low temperature cycle integrated machine adopts international professional fluorine-free refrigeration system, the main parts are directly imported, and the performance is stable and reliable. Widely used in petroleum, chemical industry, electronic instrumentation, physics, chemical and biological engineering, life science, light industrial food, physical property testing and chemical analysis, etc., to provide users with a cold and hot controlled, uniform and constant temperature liquid environment when working, can directly start the Compressor cooling at 200 ° C without damaging the Compressor, suitable for direct heating or cooling, as an auxiliary temperature source for Reaction Kettle, automatic synthesis instrument, extraction and condensation device temperature control.
Features
1. Fully enclosed environmentally friendly Compressor refrigeration system, no CFC, can directly start Compressor refrigeration at 200 ° C without damaging the Compressor
2. Temperature range -50~ 200 ℃, medium according to Temperature range to choose pure water, ethylene glycol, alcohol, methyl silicone oil
3. Built-in integrated new generation PID automatic temperature control program, equipped with High Accuracy PT100 temperature sensor, large screen high-brightness LCD display in Chinese and English, digital display resolution 0.01 ℃, to ensure Temperature Stability
4. The capacity range can be selected from 6L, 10L, 15L, 20L, 30L, 50L, 100L, and supports non-standard customization
5. The non-heat centrifugal circulation pump is used to avoid the traditional pump's own heat generation affecting the temperature field of the tank; the domestic circulation system is designed on the principle of porous U-shaped return circulation to achieve turbulence and high uniformity in the flow field and temperature field of the tank
6. The fuselage shell is anti-aging static spray, and the liner and countertop are made of S304 brushed stainless steel
7. Fine workmanship of the front panel and countertop of the chassis, humanized R rounded corner design to avoid operators being injured by edges and corners
8. The drainage system meets the needs of various laboratories and enterprises for production fluid replacement
9. Multiple Safety protection devices: power-off protection, upper and lower limit temperature alarm, low water level protection and alarm, temperature runaway protection and alarm, low water level anti-dry burning and explosion-proof heating device, Compressor overheating and overcurrent protection
Principle
The high and low temperature circulating machine realizes temperature control through the fully enclosed environmentally friendly Compressor refrigeration system, with built-in integrated PID automatic temperature control program and High Accuracy PT100 temperature sensor to ensure accurate and stable temperature. It is designed with a non-heat centrifugal circulation pump and a porous U-shaped return circulation principle to achieve turbulence and high uniformity in the flow field and temperature field in the tank, providing a constant liquid environment.
Applications
Petroleum, chemical industry, electronic instrumentation, physics, chemical and biological engineering, life science, light industrial food, physical property testing, chemical analysis, institutions of higher learning, enterprise Quality control and production departments
Standards
CFC-free environmental standards
Steps
1. Select the appropriate medium (pure water, ethylene glycol, alcohol, methyl silicone oil) according to temperature requirements
2. Set the required Temperature range, through the large screen LCD screen for Chinese and English operation
3. Start the device and the PID automatic temperature control program starts to work
4. Automatic operation of domestic circulation system to ensure uniform temperature
5. After use, change the liquid through the water discharge system
Notice
Ensure equipment operates in a safe environment to avoid external interference
• Regularly check the water level to prevent dry burning or equipment damage due to low water levels
• Pay attention to the temperature setting range to avoid exceeding the limit of -50~ 200 ° C
• Confirm that the medium type matches the Temperature range before use
• Pay attention to the rounded corner design of the chassis R during operation to avoid accidental injuries
Maintain Compressor and circulation system regularly to ensure stable performance
• If the alarm function is triggered, check and deal with the corresponding problem immediately
