Enclosed Diesel

Cummins C50D6

50kW liquid-cooled standby generator, Diesel. 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 Diesel Liquid-cooled no tank Sound Level 1 enclosure, sandstone

The C50D6 is a diesel standby set in a Sound Level 1 sandstone enclosure. It weighs 1538 lb and measures 93.8 x 34 x 45.5 inches.

This configuration ships without a tank. You will need either a base tank or a day-tank-and-bulk arrangement; we size that during the survey against your required runtime.

Diesel gives you the highest power density and fuel you can store on site, independent of the gas utility - the usual choice when the load is large, the runtime requirement is fixed, or code requires on-site fuel.

Built in

What the C50D6 does that the spec table does not show

Fuel you control

Diesel is stored on site, so the set is independent of the gas utility entirely. For a clinic, a restaurant, cold storage or a data closet that independence is usually the whole reason for choosing diesel.

1800 rpm

Half the engine speed of a residential air-cooled unit. Fewer revolutions per running hour is why these are specified where the set may run for days rather than minutes.

PowerCommand control

Digital governing, voltage regulation, alarm and status monitoring, with auto-shutdown on fault detection and NFPA 110 Level 1 compliance.

Fuel that needs managing

Diesel degrades, absorbs water and grows biological contamination if it sits. A set that runs rarely needs its fuel maintained, not just topped up — which is part of what a service visit covers.

Questions about the C50D6

How much does a Cummins C50D6 cost installed in Dallas-Fort Worth?

The C50D6 equipment price is $23,292.04. Installation on a 50kW diesel 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 C50D6 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 C50D6?

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 C50D6 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.
