TECHNICAL FEATURE
an interior cooling space, bypassing unoccupied areas
and forcing undesirable particulates up to the ceiling.
The design community should consider stratified air
systems as an additional method for optimizing indoor
air quality when designing buildings in the future.

DZR Brass
Dezincification Resistant
What is DZR brass?
DZR (dezincification resistant) brass, is a type of brass
that has a lower zinc content which makes it resistant to
the dezincification process. DZR brass is also less
prone to stress corrosion cracking.
Is DZR brass recommended for use in
hydronic systems?
Yes, DZR brass is being used in hydronic
systems across the world. This is a simple way
to improve corrosion resistance and reduce
potential costly component failures.
