Guide Review - TEC Sterling III FR Infrared Gas Grill

Bill Best is the inventor of the gas-powered infrared burner and virtually all infrared cooking equipment being used today. For the last several years, TEC has been producing gas grills using Bill's complete infrared solution.

The TEC burner (not to be confused with the considerably lower quality Char-Broil version of the same technology) converts all of the heat produced by a gas burner by passing it through a metal screen and a plate of blue tempered glass.

Apart from the higher temperatures, the advantage of infrared technology is the low airflow.

In a conventional gas grill, air is drawn in the bottom, heated and then flows over the food. This can dry out meats quickly. With this style of infrared technology, there is very little airflow. In fact, the cooking grates of this grill sit directly on top of the glass infrared converter plate. The air between the heat source and the food is trapped inside as well as the moisture the food produces. So not only does food cook faster and at higher temperatures, but with less drying.

The TEC Sterling III FR is a standard sized 3-burner gas grill. Because of the way this infrared grill works you can heat a pot on the infrared burner as effectively as if it were on a side burner. For this reason, TEC doesn't offer a side burner. Similarly, the cooking chamber is perfect for rotisserie cooking and since flare-ups are very rare you don't have to worry about burning foods on a rotisserie.
