Product Details

The NTW housing, constructed from AISI 316 electropolished stainless steel, can be equipped with a Zinc-Selenium glass window designed for thermal cameras, wavelength 7.5 - 14μm, or with Sapphire glass window for shortwave thermal cameras, wavelength 0.75 – 4.5 μm. The N TW consists of a body with a double chamber for the circulation of a cooling liquid or air. The N TW is enclosed by two thick flanges at either end and allows cables to pass through by means of two cable glands on the back flange. Two 1/2” GAS connectors allow for the cooling liquid inflow/outflow. The N TW is equipped with a flange designed to create an air barrier in front of the glass. This prevents the formation of dust deposits and attenuates the heat of the glass itself. With the supplied air barrier, the filter group is recommended, which purifies the air drawn from a compressor.

The solid construction of this housing makes it suitable for heavy duty applications, such as the surveillance of ovens, foundries, and other high temperature environments.
