Overview
The high and low temperature circulating machine adopts the international advanced environmentally friendly fluorine-free refrigeration system, the main parts are directly imported, and the performance is stable and reliable. The equipment can provide users with a liquid environment with cold and heat control, uniform and constant temperature when working. It can directly start the Compressor refrigeration without damaging the Compressor at 200 ° C. 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. It is widely used in temperature control of 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 or methyl silicone oil.
3. Built-in integrated new generation PID automatic temperature control program, equipped with High Accuracy PT100 temperature sensor and large screen high-brightness LCD screen, digital display resolution 0.01 ℃, to ensure temperature Stability.
4. Capacity range from 6L to 100L is optional, and non-standard customized production is supported.
5. Adopt non-heat centrifugal circulation pump and domestic circulation system to achieve highly uniform 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. Humanized R fillet design structure to avoid operators being injured by edges and corners.
8. Equipped with a drainage system to meet the needs of various laboratories and enterprises for production fluid replacement.
9. Multiple Safety protection devices include power-off protection, upper and lower limit temperature alarm, low water level protection, temperature runaway protection, heating device anti-dry burning and explosion-proof, Compressor overheating and overcurrent protection.
Principle
The equipment realizes temperature control through a fully enclosed environmentally friendly Compressor refrigeration system and heating device, with an integrated PID automatic temperature control program and a High Accuracy PT100 temperature sensor to precisely adjust the temperature. Using a heat-free centrifugal circulation pump and a domestic circulation system, through the porous U-shaped return circulation principle, the flow field and temperature field in the tank are guaranteed to achieve turbulence and a highly uniform state, providing users with a stable thermostatic liquid environment.
