Overview
NELE DC-4015-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. Widely used in petroleum, chemical industry, electronic instrumentation, physics, chemical and biological engineering, life science, light industrial food, physical property testing and chemical analysis research departments, colleges and universities, enterprise Quality control and production departments, to provide users with a controlled hot and cold, uniform and constant temperature liquid environment, can directly start Compressor cooling at 200 ° C without damaging the Compressor, suitable for direct heating or cooling, as an auxiliary temperature source for temperature control of Reaction Kettle, automatic synthesis instruments, extraction and condensation devices.
Features
1. Fully enclosed environmentally friendly Compressor refrigeration system, no CFC, can directly start Compressor refrigeration at 200 ° C without damaging the Compressor
2. Temperature range -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. The capacity range can be selected from 6L, 10L, 15L, 20L, 30L, 50L, 100L, and supports non-standard customization
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 the humanized R rounded corner design structure is adopted to avoid operators 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 loss protection and alarm, low water level anti-dry burning and explosion-proof heating device, Compressor overheating and overcurrent multiple protection functions
Principle
The integrated PID automatic temperature control program and High Accuracy PT100 temperature sensor are built into the high and low temperature circulation machine to achieve accurate temperature regulation. The non-heat centrifugal circulation pump and the porous U-shaped return circulation principle are used to ensure uniform liquid flow and highly uniform temperature field in the tank, providing a stable hot and cold controlled environment.
