product description

The high-low temperature cycle integrated machine adopts the latest international professional fluorine-free refrigeration system. The main components are directly imported, and the performance is stable and reliable. Widely used in petroleum, chemical industry, electronic instrumentation, physics, chemical bioengineering, medicine and health, life science, light industry food, physical property testing and chemical analysis and other research departments, colleges and universities, enterprise quality inspection and production departments, when working for users Provide a liquid environment with controlled heat and cold, uniform and constant temperature, features: the compressor can be directly started to refrigerate at 200 degrees (without damaging the compressor), and the constant temperature test can be directly carried out on the test sample or the produced product in the tank Or the test can be used for direct heating or cooling, as a temperature source for auxiliary heating or cooling, such as temperature control for reactors, fully automatic synthesis instruments, extraction and condensation devices.

technical features

Fully enclosed environmental protection compressor refrigeration system, no CFC, features: the compressor can be directly started to refrigerate under the condition of 200 degrees (without damaging the compressor).

Temperature range: optional -50～200℃ (medium is selected according to the temperature range: pure water, ethylene glycol, alcohol, methyl silicone oil).

Temperature control function: Built-in integrated new-generation PID automatic temperature control program, built-in high-precision PT100 temperature sensor 1/3B level. Equipped with a large bright LCD, Chinese and English bilingual display, digital display resolution: 0.01 ℃, to ensure temperature stability.

Capacity range: 6L, 10L, 15L, 20L, 30L, 50L, 100L, and non-standard products can also be designed and produced completely according to user requirements.

Internal circulation function: Adopt a heatless centrifugal circulation pump to avoid the influence of the traditional water pump on the temperature field of the tank due to its own heat production. The internal circulation system is designed on the principle of porous U-shaped reflux circulation, which realizes the turbulence and high uniformity of the flow field and temperature field in the tank.

The body shell adopts anti-aging electrostatic spray technology, and the liner and table are made of high-quality S304 brushed stainless steel.

The fine workmanship of the front panel and table top of the chassis, coupled with the unique humanized R rounded corner design structure, can prevent operators from being injured by edges and corners inadvertently.

The water release system can meet the needs of various laboratories and enterprises for liquid replacement.

Safety protection device:

1. With power-off protection function

2. With upper and lower limit temperature alarm setting function

3. Low water level protection and alarm function

4. Temperature runaway protection and alarm function

5. The heating device has low water level anti-dry and explosion-proof functions

6. Multiple protection functions for compressor overheating and overcurrent

Series selection

Optional function

1. An optional extended external PT100 temperature sensor can detect and control the temperature of the external system in real time during external circulation.

2. Optional built-in temperature control program of 1~30 segments can be used for automatic program temperature control and real-time display of the set temperature-time program operation status.

3. Optional RS232 or RS485 communication interface, easy to connect to the host computer, with ModbusRTU communication protocol.

4. The optional design and installation of a magnetic stirring system can directly carry out magnetic stirring on the liquid samples placed in the beakers in the working chamber of the constant temperature tank, without the need for an external vertical mixer, reducing redundant operations.

5. The built-in cooling coil in the tank can be selected to quickly cool down and control the exothermic reaction of the system.

6. An optional height-adjustable immersion loading platform can easily adjust the liquid level of the immersed sample.

7. Horizontal shape can be selected, which has the characteristics of compact structure, lower center of gravity, and strong stability.
