Overview
NELE DC-0515-II high and low temperature circulating integrated machine adopts international professional fluorine-free refrigeration system, the main parts are directly imported, and the performance is stable and reliable. The equipment provides users with a liquid environment with uniform and constant temperature when working. It can directly start the Compressor refrigeration at 200 ° C without damaging the Compressor. It is suitable for constant temperature testing or testing of specimens or products. It can also be used as a temperature source for auxiliary heating or cooling, such as temperature control for Reaction Kettle, fully 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 from 6L to 100L, can be designed and produced 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
Through the built-in fluorine-free refrigeration system and heating device, combined with the PID automatic temperature control program, the high and low temperature circulation machine realizes accurate temperature control of the liquid medium. The use of heat-free centrifugal circulation pump and porous U-shaped return circulation design ensures that the temperature field and flow field in the tank are uniform and stable, providing users with 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
