Portable cold compress machine
This product is a set of portable cold compress system, which is mainly composed of a refrigeration 280W Mini chiller, a portable ice bag, a power adapter / battery. By compressing the chiller system, the cold water which adapts to the temperature is entered into the circulation of the ice bag to achieve the effect of quick cooling, swelling and analgesia.
This product is used for various parts of the body that need to be used to cool the body, including medical rescue, special operations, firefighters, sports competitions, etc..
1. Features
| ①Small size and light weight: This is a evaporation-compression refrigeration system,installed HZSS micro heat exchanger, and it is the most small one and lightest one when compare with similar product. | ②High electric efficiency: The refrigeration efficiency of the small micro refrigeration system is about 2, which is 5 times of the semiconductor refrigeration efficiency, and is far higher than other refrigeration and cooling methods. |
| ③Easy operation: The liquid connection and electrical connection of the product are both plugged by the quick connector. | ④High temperature control accuracy： The temperature can be manually set on the touch screen, and the product can achieve the temperature control accuracy of 1 degrees centigrade. |
| ⑤High reliability and safety: product development through a series of reliability and safety testing. The factory production of each product must go through the corresponding type test (vibration, pressure, high and low temperature environment, weather resistance, oil return, condensation, protection, liquid pump / fan components such as reliability, performance, electrical safety etc). | ⑥Good environmental adoptability: |
| ⑦Add pressure treat: The liquid pressure can be adjusted, and it can also supplly pulsating pressure when cold compressing. |
