Overview
NELE DC-2010-II high and low temperature cycle integrated machine adopts international advanced 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, and can directly start the Compressor refrigeration at 200 degrees without damaging the Compressor. It is suitable for constant temperature testing or testing of specimens or products, and 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, supports direct start of Compressor refrigeration at 200 degrees without damaging the Compressor.
Temperature range can be -50~ 200 ℃, medium according to Temperature range to choose pure water, ethylene glycol, alcohol or 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. The capacity range is diverse, including 6L, 10L, 15L, 20L, 30L, 50L, 100L, and non-standard customization is supported.
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. Multiple Safety protection devices: 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 protection.
Principle
The high and low temperature circulation machine realizes temperature control through a fully enclosed environmentally friendly Compressor refrigeration system and a heat-free centrifugal circulation pump. Built-in integrated PID automatic temperature control program and High Accuracy PT100 Sensor, real-time monitoring and adjustment of temperature to ensure uniform and constant liquid Ambient Temperature in the tank. The domestic circulation system adopts the principle of porous U-shaped return circulation to promote turbulence in the flow field and temperature field and improve uniformity.
