Why Retrotec for Enclosure Integrity?

All Retrotec systems include tech support from Retrotec who originated the idea of Enclosure Integrity testing in 1984. They promoted it within NFPA and in 1986 wrote the first Enclosure Integrity standard. Retrotec has been the lead researcher for enclosure testing ever since.  Every major clean agent system manufacturer worldwide relies on Retrotec’s expertise for both hold time and peak pressure predictions.


The leakage and predicted retention time of an enclosure can be determined using the procedure in NFPA 2001, Enclosure Integrity Procedure, or by an alternative method that can be used to obtain an equivalent quantitative result. The currently preferred method is using a blower door fan unit
