CookClean CookMate
Manufacturer

The CookMate stove is made of mild steel sheets with embedded pot skirt. The combustion chamber in which the charcoal is placed has a conical shape and is relatively small compared to a traditional coal pot. The stove is equipped with adjustable sliding door. This allows food to be cooked more gradually, reducing risks of burning the food. The stove is available in 3 sizes.
