EC Modular Hi-Rise Fan Coil Units
As innovators of the Modular High-Rise fan
coil, IEC is known worldwide. All models feature removable return-air panels for easy
access to the coil, fan, electric heating and valve section, as well as for filter changes
and routine cleaning and maintenance. Standard and high-performance coils are available.
Integral risers make the units easy to install, saving many hours of labor at the
job-site. Units arrive at the job-site clearly tagged for delivery to specific zones in
the building, eliminating guesswork and delays.
