A family of hermetic enclosures dedicated to secure emergency luminaires of selected manufacturers. Due to the high degree of tightness (IP65), the housings are ideally suited to work in difficult conditions, e.g. in production halls. They are offered from two types of acid-resistant stainless steel, thanks to which they meet the corrosivity requirements C3, C4 in the sense of ISO 9223 **. The housing cover is made of transparent tempered glass or transparent PMMA.
