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.
