Lenox high-temperature, video camera systems are designed to be mounted either directly through the
wall or flush with the exterior wall of a furnace or other combustion chamber. The Lenox Furnace
Camera HD with stainless steel camera housing mounts in a 3.5 inch (89 mm) opening and employs a
steel triple wall laminar flow for efficient water-cooling of the camera and the latest optical lens
technology to provide clear, real time images, enabling operation in hostile environments up to 4250ºF
(2345ºC). The Lenox Hot Area Camera with an aluminum water-cooled camera housing enables
operation in environments up to 500ºF (260ºC) with fixed lens or 300ºF (149ºC) with window and are
ideal for hot area steel process monitoring.
Lenox high-temperature, furnace camera systems are widely used to monitor combustion and flame
pattern for possible burner malfunction; process flow for proper material position, alignment and
movement; melter material mix, formation patterns, melting point; assess refractory condition; and
other hot area processes found in steel, glass, cement, and paper manufacturing.
