Norwall PowerSystems is adding more Briggs & Stratton Standby Generator Products to give business and home owners additional options for standby power. Included are two air-cooled, three-phase standby generators, and three liquid-cooled, three-phase standby generators.

Maintenance and cold weather kits keep standby generators operating smoothly and make starting easy, even in cold weather. Stay informed wherever you are with generator status alerts via Infohub alerts on smart phones, tablets, or computers, or choose Basic Wireless Monitor.

30kW -60kW Whole House Generators

This Briggs & Stratton 30kW liquid-cooled standby generator joins the Briggs lineup of residential liquid-cooled generators at Norwall. Powered by an automotive-type liquid cooled engine, the generator supplies 25 kilowatts of power while operating on either LP or Natural Gas to supply your entire home with emergency power.

When power from the electric utility is interrupted, the generator begins to supply your entire home with power within seconds after detecting the outage. The liquid cooled generators are sold as a stand-alone generator and require an automatic transfer switch for installation.

 

Symphony II Power Management allows the generator and transfer switch to manage heavy loads like air conditioners, water heaters, and electric ranges. The Symphony Choice Control Board Kit installs in the transfer switch and works with Remote Modules to control heavy loads. Use the Symphony II 50-Amp Remote Module for 240-volt loads like electric ranges, well pumps, and electric water heaters, or one or two 120-volt loads. The Symphony II Low Voltage Remote Module and Dual Low Voltage Remote Modules control loads that use a thermostat or other type of low voltage contactor circuit.

Air-Cooled Three-Phase Commercial

The new 17 kilowatt (model 40415) and 19 kilowatt (model 40422) air-cooled generators provide three-phase (240V Delta) power during an outage. Briggs & Stratton 993cc Vanguard V-Twin engines power the generators on either LP or Natural Gas.

Eliminate your customer's lossess from power outages. Backed by one of the best commercial warranties in the industry, the three phase 19kW1 is perfect for businesses with increasing electrical demands. Designed to offer you more options, you can trust that this standby generator is a reliable choice for backup power

Less than thirty seconds after sensing an outage, the generator starts automatically and the GE Zenith automatic transfer switch isolates the building from the electric utility and begins supplying power from the generator.

While operating on Natural Gas, expect the 40415 to supply about 15.3 kilowatts and 17.1 kilowatts from the 40422.

Both three-phase generators include the Briggs & Stratton 4-year limited parts and labor warranty.

Liquid-Cooled Three-Phase Commercial

Also new to the Norwall product line are three-phase liquid-cooled standby generators in 35 kilowatts, 48 kilowattes, and 62 kilowatt models. These B&S standby generators offer three voltage configurations: single-phase 120/240V, three-phase 120/208V, or three-phase 139/240V.

Pair the Briggs & Stratton commercial standby generators with Briggs & Stratton automatic transfer switches for single phase operation, or with a GE Zenith ATS for three-phase operation.

Designed for long-term reliability, the standby generators come with the most comprehensive and longest commercial warranty in the industry—four years (1600 hours) parts & labor. The corrosion resistant enclosure eases servicing with swing-open doors that allow easy access to the engine for maintenance.

Powered by GM Vortec Engines in 8 and 4 cylinder configurations, these units are factory set to run on natural gas, but easily convert to LP gas in the field during installation. They operate at lower speeds for less wear and tear, low noise, and better fuel efficiency. Look for an approximate 10 percent reduction in available power while operating on natural gas.
