SYSTEMS 18RULX, 24RULX, 36RSLX
The universal mount 18RULX and 24RULX are ideal
for a house of worship to mount beneath stained glass
windows. Lower in height than the pews, they do not
disturb the aesthetics of the space. With long piping
lengths of 165' the outdoor units can also be placed
remotely out of sight. Another popular application for
this model is in hallways where wall space is limited.
The 36RSLX is popular where fresh air intake and
high capacity is required like a restaurant or bar. They
are also often suspended from threaded rod and used
in multiple to condition large warehouse spaces.
