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.
The NTW housing, made of polished stainless steel AISI 316L, can be equipped with a zinc selenide (ZnSe) window designed for thermal video cameras (with a wavelength from 7.5μm to 14μm), or a sapphire glass window for shortwave thermal video cameras (with a wavelength from 0.75μm to 4.5μm).
The NTW housing consists of a body with double chamber for the circulation of coolant or cooling air, closed by two very thick flanges. The rear flange enables cable passage using two cable glands PG13.5. Two 1/2” GAS connectors control the input/output of cooling fluids.
The housing is equipped with a flange designed to create an air barrier in front of the window, with the dual purpose of preventing dust deposits and reducing the temperature. We recommend using the filter unit with the air barrier to clean the air normally suctioned by a compressor and, therefore with the presence of oil particles.
