Overview
NELE DC-4010-II high and low temperature cycle integrated machine adopts the international advanced 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 and other research departments, colleges and universities, enterprises Quality control and production departments, to provide users with a controlled hot and cold, uniform and constant temperature liquid environment when working. It is characterized by direct start of Compressor refrigeration at 200 degrees (without damaging the Compressor), which can be used for direct heating or cooling, as an auxiliary heating or cooling temperature source, such as temperature control for Reaction Kettle, automatic synthesis instrument, extraction and condensation device.
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 can be selected pure water, ethylene glycol, alcohol, methyl silicone oil.
3. Built-in integrated new generation PID automatic temperature control program, 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 non-standard products can be customized.
5. The non-heat centrifugal circulation pump is used to avoid the traditional water pump from affecting the temperature field of the tank due to its own heat generation; the domestic circulation system is designed with the principle of porous U-shaped return circulation to achieve turbulence and high uniformity of the flow field and temperature field in the tank.
6. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel.
7. The front panel and countertop of the chassis are finely crafted, with a unique and user-friendly R-rounded design structure 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 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 functions.
Principle
The high and low temperature circulation integrated machine realizes accurate temperature regulation 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 reflux circulation to ensure that the liquid temperature in the tank is uniform and constant, avoiding the traditional water pump heat generation affecting the temperature field.
Applications
Petroleum, chemical, electronic instrumentation, physics, chemistry, biological engineering, life science, light industry food, physical property testing, chemical analysis and other research departments, colleges and universities, enterprise Quality control and production departments
