Daikin Water Cooled VRV®-WIII Daikin's VRV®-WIII is a
compact water cooled condensing unit designed for use in hotel, office
or any size commercial building. It provides exceptional energy and
cost savings as well as providing a solution for geothermal applications
which also qualifies for a possible business investment tax credit.
Daikin's modular design allows access to a wide range of applications in
spaces where traditional centralized plants are not suitable or
cost-effective. At only 330 lbs. and less than 40” high per module,
the VRV-WIII can be transported in a standard elevator and allows for a
double stacked installation. Flexibility is Everything. Visit www.daikinac.com

How to make tighter pipe runs Click here to see how to be more creative and
more efficient in your pipe runs. Metraloop expansion joints let you
make pipe runs more compact and protect piping from 360º movement. You
can use the Metraloop’s compact profile to squeeze into places other
where other joints can’t. Use Metraloops for seismic applications, gas
connections, steam piping, water and chemical pipes. Click here make a more efficient pipe
