Overview
NELE DC-3020-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, chemistry, 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 and environmentally friendly Compressor refrigeration system, no CFC, can directly start Compressor refrigeration at 200 ° C (without damaging the Compressor).
Temperature range can be -50~ 200 ℃, medium according to Temperature range to choose pure water, ethylene glycol, alcohol, methyl silicone oil.
3. Integrate a new generation of PID automatic temperature control program, built-in 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. Capacity range from 6L to 100L, non-standard products can be designed according to user requirements.
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 with the principle of porous U-shaped return circulation to achieve turbulence and high uniformity in the flow field and temperature field in 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, and user-friendly 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. Safety protection device includes 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 multiple protection.
Principle
The high and low temperature circulation integrated machine realizes accurate temperature adjustment through the fully enclosed environmentally friendly Compressor refrigeration system and PID automatic temperature control program. The domestic circulation system adopts the principle of no-heat centrifugal circulation pump and porous U-shaped return circulation to ensure the uniform and stable liquid temperature in the tank and avoid the traditional water pump heat generation affecting the temperature field.
Applications
Petroleum, chemical industry, electronic instrumentation, physics, chemistry, bioengineering, life sciences, light industrial food, physical property testing, chemical analysis
