Overview
NELE DC-4030-II high and low temperature cycle integrated machine adopts international professional fluorine-free refrigeration system, the main parts are imported, and the performance is stable and reliable. The equipment provides users with a cold and hot controlled, uniform and constant temperature liquid environment when working. It can directly start Compressor refrigeration at 200 ° C without damaging the Compressor. It is suitable for constant temperature testing or testing of specimens or products, and can be used as a temperature source for auxiliary heating or cooling, such as temperature control for Reaction Kettle, automatic synthesis instruments, extraction and condensation devices.
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. 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. Capacity range includes 6L, 10L, 15L, 20L, 30L, 50L, 100L, and 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 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, 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 functions.
Principle
The high and low temperature circulating machine realizes accurate temperature control of the liquid environment through the fully enclosed environmentally friendly Compressor refrigeration system and the integrated PID automatic temperature control program, combined with the High Accuracy PT100 temperature sensor. The non-heat centrifugal circulation pump and the porous U-shaped return circulation design ensure that the flow field and temperature field in the tank are uniform and stable, and provide a constant temperature environment.
Applications
Research departments of petroleum, chemical industry, electronic instrumentation, physics, chemical and biological engineering, life science, light industrial food, physical property testing, chemical analysis, etc., colleges and universities, enterprise Quality control and production departments
Steps
1. Select the appropriate medium (such as pure water, ethylene glycol, alcohol, methyl silicone oil) according to the Temperature range.
2. Turn on the power of the device and set the required temperature and control parameters through the large-screen LCD screen.
3. Start the domestic circulation system to ensure uniform circulation of liquids.
4. Put the specimen or product into the tank for constant temperature test or test.
5. After use, turn off the power of the device and perform the fluid change operation as required.
Notice
• Ensure that the equipment is used in a safe environment and avoid wet or flammable items.
• Check the water level before use to prevent dry burning or damage caused by low water level operation.
• Regularly maintain the refrigeration system and circulating pump to ensure stable performance.
• Pay attention to the rounded corner design of the chassis R during operation to avoid accidental collisions.
• Follow the Safety protection function settings, and deal with the alarm in time.
• Non-professionals should not disassemble or modify the internal structure of the equipment.
