TEC's original ceramic infrared technology, introduced in the 1980's, was a great improvement over traditional convection style grilling. Convective grills cook food with 100% hot air, and hot air dries outr food. But TEC's ceramic infrared burners cooked with 35% infrared heat and 65% hot air so food retained more of its natural juices. All other infrared grills today use these ceramic burners but TEC's new patented grilling system cooks with 100% infrared energy. These grills totally eliminate the hot air associated with gas grilling, so food retains the maximum amount of moisture. As a result, moisture loss and food shrinkage are reduced by up to 30% - even well done meats remain tender and juicy.
