Restricted Breathing is a method of construction for an enclosure such that the possibility of entry of a surrounding explosive gas or vapor atmosphere is reduced to a low level. The design includes a very high level of sealing which limits the possible entry of flammable gas or vapors. This protection technique may be used in a Zone 2 classified location where explosive atmospheres are present in abnormal conditions only for short periods (typically less than 10 hours per year).

These enclosures are custom designed and engineered for your specific application or project.
