Vener 7 · Oil-cooled
Oil-Cooled AVR Range
For three-phase installations where efficiency, heat dissipation and continuous duty matter. Transformer-grade mineral oil carries heat away from the windings, letting the unit run cooler under sustained full load than an equivalent air-cooled design. Available from 10 kVA up to 3000 kVA, indoor or outdoor-cabinet.
Key features
Transformer-grade mineral oil cooling (class ONAN)
Higher efficiency under continuous full load
Better heat dissipation in hot ambient conditions
Outdoor cabinet versions available (IP-23)
Three-phase only, 10 to 3000 kVA
Lower noise than forced-air designs
