Overview
NELE DC-40100-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. 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, 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 can be selected 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 can be customized for non-standard products.
5. The domestic circulation system of non-heat centrifugal circulation pump and the principle of porous U-shaped reflux circulation are used to achieve turbulence and high uniformity in the flow field and temperature field in the tank.
6. The fuselage shell is anti-aging electrostatic spray, the liner and countertop are made of S304 brushed stainless steel, and the humanized R rounded corner design avoids operator injury.
7. The drainage system meets the needs of various laboratories and enterprises for production fluid replacement.
8. Safety protection device includes power-off protection, upper and lower limit temperature alarm, 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 circulating machine realizes accurate temperature control of the liquid environment through the fully enclosed environmentally friendly Compressor refrigeration system and PID automatic temperature control program, combined with the High Accuracy PT100 temperature sensor. The use of a heat-free centrifugal circulation pump and a porous U-shaped return circulation design ensures uniform temperature distribution in the tank and provides a stable hot and cold controlled environment.
