Does a microheat adsorption dryer fall under the category of special equipment?
Thread Content
There are several micro-heat adsorption dryers at the construction site. These dryers consist of an adsorption cylinder, a separation tank, and a cooler; all of these components fall under the category of pressure vessels. Of course, in addition to these parts, the dryer also includes a heater, electrical control components, and a frame. So the question is: as the installation contractor, do we need to inform the local quality and technical supervision agency before installing the dryers?
Are there any pictures? If it is classified as a pressure vessel, it needs to be inspected by the local quality supervision bureau, with inspections carried out annually
