This powerful new dual-element CD-Series fixture provide concentrated heat for larger scale applications in high visual impact locations. Extend the lifespan of your Infratech heater in climates with exposure to saltwater and other extreme elements with our new Marine UpGrade. It combines the designer-friendly profiles of our products with our most durable, high-grade anti-corrosive 316 stainless steel construction. While all Infratech heaters feature corrosion-resistant 304 stainless steel, 316 is a highly metallic element that offers enhanced protection and enduring style in coastal, alpine, windy, humid and other demanding conditions. The flush mount frame is also offered in this option to support our most popular installation choice.
