Portable cooling machine for high temperature gas liquefaction
The product is a cooling machine for high temperature gas liquefaction, applicated in environmental testing samples, micro chemical online refrigeration and ect.This product is provided with a handle and one hand portable. Products can be equipped with anti-vibration base, without special installation, It can work when flatted on the water platform or ground.
1. Product features
| ①Small size and light weight: The weight of the whole machine is only 4.9kg, and the size is only 290mm (L) x 178mm (W) x 205mm (H), which can be carried by one person. | ②High 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 refrigerant 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: |
| ⑦High refrigerating capacity: When the ambient temperature is 30 degrees and the outlet water temperature is 20 degrees centigrade, the refrigerating capacity is 400W. The specific gas liquefaction ability is related to latent heat and specific heat capacity. |
