Overview
NELE DC-1010-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 and other research departments, colleges and universities, enterprise Quality control and production departments, provide users with a hot and cold controlled, uniform and constant temperature liquid environment when working, can directly start the Compressor refrigeration at 200 degrees, and conduct constant temperature tests or tests on specimens or products as an auxiliary heating or cooling temperature source.
Features
1. Fully enclosed and environmentally friendly Compressor refrigeration system, no CFC, can directly start Compressor refrigeration at 200 degrees (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. Built-in integrated new generation PID automatic temperature control program, equipped with High Accuracy PT100 temperature sensor 1/3B level, large screen high-brightness LCD screen Chinese and English display, 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 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.

7. The front panel and countertop of the chassis are finely crafted, and a humanized R-rounded design structure is adopted to avoid the operator 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 setting, 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 that the liquid temperature in the tank is uniform and constant, avoiding the influence of traditional water pump heat generation. The equipment can directly start the refrigeration in the high temperature state without damaging the Compressor, providing a stable hot and cold controlled environment.
Applications
Petroleum, chemical industry, electronic instrumentation, physics, chemical and biological engineering, life sciences, light industrial food, physical property testing, chemical analysis, research departments, colleges and universities, enterprise Quality control, production departments
Notice
• Make sure the power supply of the equipment is connected correctly before use to avoid voltage instability affecting operation.
• Regularly check the water level to prevent low water levels from causing the equipment to dry or alarm.
• Pay attention to the temperature setting during operation to avoid triggering an alarm beyond the upper and lower limits.
• Keep the equipment clean to avoid impurities entering the circulation system affecting performance.
When starting refrigeration at high temperature, ensure that there is no abnormality in the Compressor to prevent overheating or overcurrent.
• When changing the medium, select the appropriate liquid such as pure water and ethylene glycol according to the Temperature range.
• When using the external circulation function, check whether the connecting pipeline is firm to prevent leakage.
When the equipment is running, avoid touching high or low temperature parts to prevent burns or frostbite.
• Safety protection function tests are carried out regularly to ensure the normal operation of power-off protection, temperature alarm, etc.
