To substantially reduce noise to the ultmost, we divide-and-conquer noise from 3 levels： 1) The highest noise is caused by motor rotation - we use high-quality pure copper motor, and do the best matching of voltage and speed to reduce noise2) Moderate noise is caused by airflow - Poor airflow design leads to relatively large noise, which affects the cooking mood. This is the problem with similar products on the market at present. In order to solve this problem, we apply upgraded fan blades to promote better air circulation effect; the heating hood and steam hole openings fully consider the direction and angle of wind convection to achieve a good exhaust system and reduce wind resistance to reduce noise.3) Low noise is caused by the vibration of components and parts - 4 fixed support feet at the bottom to reduce the vibration of different parts of the air grill to reduce noise. Adoolla Contact Grill features a traditional Stainless Steel heating tube, as well as a Halogen heating tube that expedites heating up to 450°F. Additionally, the aerodynamic air duct allows for small temperature discrepancies along parts of the grill plate, resulting in thorough and even searing.
