USED 1984 KOHLER 55RZ82

Kohler 55RZ82 Fast Response LP Generator SetEngine: 6-Cylinder In-Line | Rating: 50 kW / 62.5 kVA | Fuel: LP / Natural GasProfessional OverviewThe Kohler 55RZ82 is a mid-range industrial standby generator set featuring Kohler’s patented "Fast Response" alternator technology. This system is designed to provide exceptionally stable power and rapid voltage recovery during large block-load applications, making it a favorite for small commercial buildings, municipal pump stations, and residential estates. The 55RZ82 is typically powered by a heavy-duty, 6-cylinder in-line industrial engine, offering a simpler maintenance profile compared to larger V-style engines.Technical SpecificationsStandby Rating: 50 kW / 62.5 kVA (at 0.8 power factor).Engine: 6-Cylinder In-Line (Industrial water-cooled).Speed: 1800 RPM (60 Hz).Voltage: Commonly 120/208V, 3-Phase (Multi-tap / Reconnectable).Alternator Type: Fast Response, Brushless, Permanent Magnet (PMG).Weight: Approx. 2,300 lbs.Dimensions: Approx. 89" L x 38" W x 47" H.Key Performance FeaturesFast Response Technology: The alternator uses a permanent magnet excitation system that allows it to respond to load changes faster than standard externally regulated alternators. This ensures sensitive electronics are protected from significant voltage dips during heavy motor starting.Gaseous Fuel Versatility: This unit is primarily configured for LP (Propane) Vapor or Natural Gas, allowing for long-term standby use without the fuel degradation issues associated with diesel.Reliable In-Line Engine: The 6-cylinder in-line design is widely respected for its balance and ease of service access, with all major maintenance points (filters, plugs, belts) typically located on one side.Solid-State Voltage Regulation: Features high-precision regulation (±0.25% to ±1.0% depending on the specific controller model), crucial for maintaining consistent frequency and voltage in standby applications.
