Clinics, restaurants, data closets, cold storage, multi-tenant retail and small industrial. Representative manufacturer image of the range. Enclosure finish, color and dimensions vary by model and configuration — see the specifications below for this unit. 150 kW Natural Gas / LP Vapor Liquid-cooled Aluminum The RS150 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 - 143 x 40 x 72 inches and 3915 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. Pricing Quoted per project Units at this size are specified against your electrical service, switchgear and fuel arrangement, so they are quoted per project rather than listed at a shelf price. The RS150 is sold by UTS ElectricPros, an [authorized Cummins dealer](https://utselectricpros.com/about) in Dallas–Fort Worth. Buying through an authorized dealer is what keeps the [manufacturer warranty](https://utselectricpros.com/warranty) valid — equipment bought from an unauthorized reseller frequently is not covered, and owners tend to find that out at the worst possible moment.

Built in ## What the RS150 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.

The RS150 is quoted per project rather than listed at a shelf price. Units at this size are specified against your electrical service, switchgear and fuel arrangement, so a shelf number would be meaningless. Tell us the application and we will put equipment and installation in writing together. ### What will the RS150 actually run? Commercial standby power for facilities with substantial motor and HVAC load. 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 RS150? 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 RS150 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 150kW 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 125kW — less headroom, lower install cost. ### [Cummins RS125](https://utselectricpros.com/generators/rs125) Liquid-cooled · Natural Gas / LP Vapor Pricing Quoted per project Units at this size are specified against your electrical service, switchgear and fuel arrangement, so they are quoted per project rather than listed at a shelf price.

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. The RS150 is installed across the Dallas–Fort Worth Metroplex by our own licensed crews — [the cities we serve](https://utselectricpros.com/service-areas), [what installation involves](https://utselectricpros.com/installation), and [a free on-site survey](https://utselectricpros.com/quote) before any number is put in writing. ## Before you buy the RS150 The questions that decide whether this is the right machine, answered properly rather than in a sentence on a product page. - [Is 150kW the right size for the load?](https://utselectricpros.com/sizing-calculator) Size against the connected load and the starting surge, not the floor area. - [Natural gas or propane?](https://utselectricpros.com/guides/natural-gas-vs-propane-vs-diesel) Fuel decides runtime, refueling and what the gas side of the install costs. - [How loud is it, really?](https://utselectricpros.com/guides/how-loud-is-a-standby-generator) Published dB by model, and what that sounds like from a neighbor’s window. - [Will my gas line carry it?](https://utselectricpros.com/guides/gas-line-sizing-for-a-generator) The most common reason a quote moves after the survey. Real BTU demand and the pressure it needs under load. - [What can my city require?](https://utselectricpros.com/guides/city-generator-permit-rules-texas) Less than it used to, and a third party can now do the inspection.
