Overview
NELE DC-3020 (horizontal) Low Temperature Circulating Bath is a High Accuracy temperature control equipment, using fluorine-free environmental protection refrigeration system and imported core components, with stable and reliable performance. It is used for research, teaching, Quality control and production departments in the fields of petroleum, chemical industry, electronic instrumentation, physical chemistry, bioengineering, life science, light industrial food, physical property testing and chemical analysis. It provides a liquid environment with controlled heat and cold and uniform temperature. It can be directly used for sample thermostatic testing or as an auxiliary temperature control source for Reaction Kettle, synthetic instruments, extraction and condensation devices.
Features
1. Adopt a fully enclosed environmentally friendly Compressor refrigeration system, free of CFCs.
2. Temperature control precision, digital resolution of 0.01 ℃, temperature fluctuation of +/- 0.05 ℃.
3. The domestic circulation system adopts a non-heat centrifugal circulation pump, combined with the porous U-shaped return design, to ensure that the flow field and temperature field in the tank are highly uniform.
4. The fuselage shell is anti-aging static spray, the liner and countertop are made of S304 brushed stainless steel, with fine workmanship and humanized R rounded corner design.
5. Safety protection with multiple functions, including power-off protection, temperature alarm, low water level protection and alarm, temperature runaway protection, heating device anti-dry burning and explosion-proof and Compressor overheating and overcurrent protection.
6. Provide a variety of functions, such as external temperature sensor, program temperature control, Communication interface, magnetic stirring system, built-in chill down coil, adjustable immersion loading platform, etc.
7. Optional horizontal shape, compact structure, low center of gravity, Stability.
Principle
The device monitors the liquid temperature in the tank in real time through the built-in High Accuracy PT100 temperature sensor, and transmits the signal to the integrated PID automatic temperature Control system. The system precisely controls the operation of the refrigeration system (fully enclosed and environmentally friendly Compressor) or heating system according to the deviation of the set value and the measured value to maintain the target temperature. At the same time, the device drives the liquid in the tank for domestic circulation through the heat-free centrifugal circulation pump, and adopts the porous U-shaped return principle to promote liquid turbulence, so as to achieve a high degree of uniformity and stability of the temperature field in the tank.
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
Notice
• Temperature range according to the required selection of the appropriate circulation medium (such as pure water, ethylene glycol, alcohol, etc.).
• Please ensure that the water level of the equipment is normal before use to avoid triggering protection or causing dry burning of the heating device during low water level operation.
• Safety protection function settings of the equipment, such as temperature upper and lower limit alarms, etc., and ensure that it is in normal working condition.
• When connecting external circulation or using optional functions (e.g. magnetic stirring, chill down coil), please refer to the relevant instructions for correct operation.
• Keep the equipment well ventilated to avoid the Compressor triggering protection due to overheating.
• The drainage system can be used for laboratory or production fluid change, please pay attention when operating.
