AIRSMART™ CONTROL SYSTEM
L11VS – L18VS compressors are easy to use,L11VS – L18VS compressors are easy to use
thanks to the new and advanced AirSmart™h k t th d d d Ai S t
controller. You don’t need to be an expert on
variable speed drives to operate the CompAir
L_VS compressors. The controller takes care
of the details. It auto matically adjusts the
compressor performance to meet your
changing air system demands and saves
your energy costs.
AirSmart™ control system also includesAirSmart™ control system also includes
• Smart energy cost calculationS t t l l ti
• Pressures from 3 to 13 bar
• Integrated sequencing option
• Clear text indicator display
• Multiple languages
• Prevention of reverse rotation
INTEGRATED REFRIGERANT DRYER OPTION
COMMUNICATION AND SEQUENCING
The optional communication module allows the AirSmart™
units to talk to each other. This isn’t just an hour-balancing,
on/off sequencing function. Our controller allows the
system to truly optimize the efficiency because it knows s
the capabilities of the other machines and controls their th
operation. The communication module also allows
remote monitoring of the L_VS and fixed speed units,
providing better energy efficiency in part load operation.p
MAXIMUM FLEXIBILITY
Thanks to the new highly functional AirSmart™ control T
system, the new L11VS – L18VS series allows you to
choose any delivery pressure from 3 to 10 bar orc
from 10 to 13 bar depending on model. Options includefr
the i ntegrated refrigerant dryer, condensate handling
equipment and a wide selection of compressed air filters.e
These options are available to enable you to build aT
complete compressor station for your needs.c
LOW NOISE LEVELL
The sound-engineered enclosure of L11VS – L18VS
absorbs noise effectively. The package is so quiet, that ita
can be installed exactly where it is needed without any
special consideration for noise. This series is simply as
smart design with high quality parts. Quiet fan, segregated s
cooling air flow, plus motor and air end are isolated to
prevent noise transmission.p
SUPERB REGULATION RANGES
Flexibility comes as standard with the L_VS series.
With a 15 – 100% capacity range, the L_VS series features
quick and wide response to air demand changes.
EASY MAINTENANCE
This series has an advanced automatic belt-tensioning
system, which gives the optimal belt-tension in all
conditions. Due to its compact enclosure, the series
requires limited floor space and the installation of the
package is quick and efficient.
The use of high quality compoonents guarantees a long
service life. CompAir has a nettwork
of trained service providers
available whenever required too
ensure your compressor achieeves
the highest level of reliability.
