What is a HMD ?
HMD is the abbreviation of Heat Management Device. As the name suggests, this device is used to regulate heat. When smoking hookah, the ideal state is to maintain the perfect amount and concentration of smoke in the whole hookah session. As we all know, the heat of charcoal is reduced slowly in the process of combustion. Therefore, if you let the coals work in an unobstructed environment (such as directly placed on foils), Obviously not
A charcoal Holder = HMD ?
Therefore, we need a device that can hold the burning coals. Prevent the coals from burning rapidly due to contact with a large amount of oxygen. But just a charcoal holder is not enough for us to call it "HMD".
