This thermographic image demonstrates the uniform temperature distribution of an Delta T Dish system. Notice that the dish temperature is so uniform that its location, in infrared, is indistinguishable from the stage. This demonstrates the effectiveness of the dish as well as the safety of surrounding instrumentation. Delta Breez ventilation fans are ENERGY STAR® qualified and some have been designated ENERGY STAR Most Efficient 2023, which recognizes the top products for the ENERGY STAR label. Except for BreezRadiance series with Heater, which have a powerful 1300W/1600W heating element for warmth and comfort.
