Infratech SL4024BL 63.50" Slim Line Black Shadow 4,000 Watt 240 Volt 16.7 Amps

High-Performance Infrared Warmth with an Ultra-Low Profile Silhouette

The Infratech SL4024BL Slim Line "Shadow" heater is the ultimate fusion of raw power and minimalist architectural design. Measuring 63.50 inches in length, this 4000-watt, 240-volt single-element heater (16.7 amps) is engineered to provide expansive radiant heat for large-scale outdoor living areas, high-end patios, and commercial dining zones. The Slim Line series is renowned for its sleek, narrow housing, making it the premier choice for designers who require significant heat output without the bulky visual footprint of traditional heaters. By utilizing medium-wave infrared technology, the SL4024BL warms people and surfaces directly—bypassing the cold air—to deliver consistent, sun-like comfort even in exposed or breezy environments.

Shadow Series Aesthetic: The Art of Disappearing Design

Finished in a premium Matte Black "Shadow" coating, the SL4024BL is designed to vanish into modern architectural details. This sophisticated dark finish is the perfect match for black powder-coated pergolas, dark-stained wood ceilings, and industrial-chic steel structures. Beyond its aesthetic appeal, the high-temperature finish is exceptionally durable, providing a corrosion-resistant layer that protects the 304 stainless steel housing from the elements. This model doesn't just heat your space; it preserves the clean, unobstructed lines of your vision, providing "invisible" warmth that lets your architecture take center stage.

Versatile Engineering for Seamless Professional Installation

The SL4024BL is designed for maximum installation versatility, performing at its peak when mounted at heights between 8 and 11 feet. Its unique T-slot mounting system allows the brackets to be positioned anywhere along the back of the heater, providing a clean, "bracketless" appearance from the front. This 4000-watt powerhouse is fully compatible with Infratech’s sophisticated control array, ranging from simple on/off switches to high-amp timers and advanced solid-state dimmers for precise heat intensity management. Operating completely silently with zero emissions or odors, it offers a sustainable and highly efficient alternative to bulky gas-fired heaters, requiring no fuel tanks or complex ventilation.
