FEATURES
HARDWARE FEATURES : Maximum modularity and scalability of the system from
economical compositions “single exciter” to redundant custom compositions
“double exciter”.
POWER & QUALITY: With the family of RVR’s liquid transmitters based on
the U-KLC series, is possible to realize compact equipments up to 20kW, with
high energy savings thanks to the use of high efficiency pumps and no forcing
ventilation. The Cooling system is with low pressure circuit and double pump
in automatic switching and diagnostics.
RELIABILITY & REDUNDANCY (business continuity): Extremely safe operation:
by pressing the emergency button is cutting the power supply line to the
various relay switches while remaining exciters operational.
USER-FRIENDLY FEATURES : user-friendly software and a simple, intuitive
HM interface let you easily set up and control all machine operating
parameters. user-friendly software and a simple, intuitive HM interface let
you easily set up and control all machine operating parameters.
EASE OF MAINTENANCE: accessibility and ease of maintenance are ensured by
advanced modular engineering concepts incorporated in the transmitter and by
its lightweight components. Better cleaner work environment and low
environmental noise.
REMOTE CONTROL: the device comes with a powerful, complete telemetry
system.
