This product is an active dehumidification device, which can provide air drying, vacuum pumping, and airtightness testing for all kinds of sealed containers. Because the air in the sealed container will inevitably contain water vapor, at this time, if the sealed container is arranged in an environment with a large short-term temperature difference, especially the wading container, the external environment temperature drops, the water vapor near the container wall condenses and forms water droplets, which is easy to cause damage to the electronic devices in the container.
At present, most of the industrial dehumidification equipment that can be realized in the sealed container is complicated in operation and requires the support of many large accessories, which are complicated in operation and expensive in price.
Another relatively simple way of dehumidification is to preset the desiccant in the container box cover in the container, through the “passive” dehumidification, but this method not only occupies the precious space in the sealed container, and the desiccant utilization rate is low, the dehumidification effect is not obvious, the desiccant is not easy to replace.
This device can realize “one machine multi-purpose”, and small and portable, easy to operate, high reliability. Compared with similar products on the market, it has the advantages of low price, obvious dehumidification effect and rapid dehumidification process, high vacuum degree, and low maintenance cost of equipment.
The main body of the equipment includes a vacuum dehumidification box and a vacuum valve. The vacuum dehumidification box manufactured by the company has a high-performance vacuum pump, which can be pumped out the air in the sealed container, so that the external air enters the container after drying, so as to realize the replacement of the relatively moist air in the sealed container, thus reducing the water vapor content in the sealed container. The equipment also includes a set of self-developed vacuum valves, through this device, the theory is that the product can achieve a vacuum degree of 85% (-85KPa) in the sealed container. The shell of the equipment is PP engineering plastic, light and wear-resistant, shockproof and compression resistant, easy to carry.
