Estate properties and small commercial buildings that cannot afford a dark day. Representative manufacturer image of the range. Enclosure finish, color and dimensions vary by model and configuration — see the specifications below for this unit. 50 kW Natural Gas / LP Vapor Liquid-cooled Aluminum The RS50 is liquid-cooled. That matters above roughly 25kW, where an air-cooled engine can no longer shed heat during the long runs a multi-day outage demands. It is a larger machine - 118.7 x 40 x 58.3 inches and 2403 lb - and it needs a proper pad and clearance. It runs on natural gas or LP vapor. On natural gas there is no tank to fill and no runtime limit as long as the utility main holds pressure, which is why it is the default choice on almost every DFW home that already has gas service. Available in 4 factory configurations: 120/240 1Ph, 120/208 3Ph, 277/480 3Ph, 120/240 3Ph. The correct one depends on your incoming service, not on preference - ordering the wrong voltage is the single most expensive mistake on a job like this, so we confirm it against your meter and panel before anything is ordered.

Built in ## What the RS50 does that the spec table does not show ### 1800 rpm, not 3600 Liquid-cooled sets turn at half the speed of an air-cooled unit. Fewer revolutions per hour of running means less wear, and it is a large part of why these are quieter despite being far more powerful. ### Sound Level 2 enclosure From 60 dB(A) at 23 feet on the smaller sets. A 30kW liquid-cooled unit is quieter than a 20kW air-cooled one. ### PowerCommand control Electronic governing and voltage regulation, with alarm and status monitoring. Regulation is tighter than the air-cooled range at ±1.0%. ### Continuous rated output A radiator loop means it can hold rated output indefinitely rather than shedding heat into the air. That is the practical difference in a multi-day outage.

From $5,021.81 ## Questions about the RS50 ### How much does a Cummins RS50 cost installed in Dallas-Fort Worth? The RS50 equipment price is $23,364.26. Installation on a 50kW liquid-cooled unit varies too widely to band honestly - the pad, the fuel supply, the switchgear and the electrical service are all engineered to the specific site. We quote it in writing after a site survey, and we will tell you the drivers before we quote so you can see where the money goes. ### What will the RS50 actually run? Estate homes, or light commercial loads such as a small clinic, restaurant, retail suite or office. Final confirmation comes from a load calculation against your actual panel, which we do at the survey. ### Do I need a transfer switch with the RS50? Yes. A standby generator cannot be code-compliantly connected without an automatic transfer switch - it is what keeps your generator from backfeeding the utility line and endangering line crews. The switch is sized to your electrical service, not to the generator, so we confirm your service size at the survey before specifying it. ### Is the RS50 in stock? Availability changes weekly. A refundable deposit reserves a specific unit and locks the equipment price for 90 days, which is the practical way to hold one while the survey and permit work happen. If we cannot source it in a reasonable window, you get the deposit back. Step up or down ## Is 50kW the right size? The next capacity either side in the liquid-cooled range. If you are not sure which way to go, the [sizing calculator](https://utselectricpros.com/sizing-calculator) works it out against your own house rather than its square footage alone. Down to 40kW — less headroom, lower install cost. ### [Cummins RS40](https://utselectricpros.com/generators/rs40) Liquid-cooled · Natural Gas / LP Vapor 120/240V single phase $19,495.69 Equipment only.

Refrigeration thaws, the point of sale goes dark, card payments fail, doors and tills stop working and staff get sent home. For a clinic or a restaurant it is not only lost revenue, it is a food-safety and patient-care obligation. ### Why it becomes urgent The same storm and grid events that take out homes take out the block the business sits on, and a commercial outage costs money by the hour from the first minute. ### Who buys it Offices, clinics, restaurants, retail suites and small industrial buildings that cannot close for a day.
