NTWLiquid-cooled housing for thermal cameras



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.


Made of AISI 316L electropolished stainless steel

Effective monitoring even in complete darkness or in extreme environmental conditions, fog, rain or smoke

For industrial installations with high-temperatures in corrosive environments

For temperatures up to 400°C (752°F)

Supplied air barrier
