Diesel Generators for Sale

Diesel generators for sale in Alberta, priced on the unit, not the model.

Industrial diesel generators rated from 60 kW to 500 kW, offered for purchase from our Red Deer yard. The specification is on each listing. The price is not, because it is worked out for the set you choose and sent to you in writing.

What you are buying

The listing says what condition it is in, or you ask before the quote.

A kilowatt figure says nothing about how much life is left in the engine behind it. When we list an industrial diesel generator for sale, one of the three terms below describes it. If a listing does not use any of them, ask which applies before a price is put on it.

Used

The engine has done paid work on someone's site. The hour-meter reading and any rebuild history matter more than the build year, because together they tell you how far into its life the set is. Ask for both, and for what was done at each rebuild.

New vs. used buying guide →

New surplus

Bought for a project or for stock and never commissioned, so it has no working history, but it is not fresh either. Its age comes from sitting rather than running. Ask how and where it was stored, and what has been checked since: batteries, hoses, coolant and fuel.

New

No service life at all beyond the manufacturer's own testing. Do not read it into a listing that does not say it. If a new set is a requirement for your project or your client, tell us at the start and we will say whether anything listed qualifies.

Before you commit

Settle these four, then talk price.

01

Hours and condition, in writing

Get the hour-meter reading and the condition term onto the quote itself. A figure mentioned on the phone is not part of what you bought; a figure on paper is.

02

Standby or prime: which rating the kW is

A diesel set's standby rating is higher than its prime rating, because standby assumes short, occasional runs. If you want a prime power generator for sale, ask which of the two the listed kW is before you size a load against it.

03

The engine's emissions label

If a permit, the site owner or your client names an emissions Tier, the engine has to meet it. Ask us to confirm the label on that exact unit before you buy, rather than going by the model name.

04

An hour at real load

An engine that has been parked will usually start. What you need to know is how it behaves with a heavy load on it for an hour: oil pressure, coolant temperature, and whether the output stays steady. Load banks are in the same fleet, so ask for that run before you commit.

Unsure how long you will need it? Rent before you buy.

Owning a diesel set pays off once the load is known to be staying and you know its size. When either of those is still in doubt, a rental term is a cheaper mistake than a purchase sized for the wrong job. A unit's listing shows whether it is also offered for rent, with a For Rent badge beside the For Sale one. If the set will spend most of its life waiting for an outage, emergency standby generators explains how that duty is specified before you choose between renting and owning.

Buying diesel

Questions to ask before you ask for a price.

What is the price of a diesel generator in Alberta?

There is no single figure, and we do not publish one. Two diesel sets with the same kilowatt rating can differ in hours, condition, enclosure, fuel tank and control panel, and each of those changes what the set is worth. Pick a unit from the listings, or describe the load, and we will quote a set in writing. Call (403) 887-4567 to start.

Are these diesel generators new, surplus or used?

Where the condition is known, the listing states it. Used means the engine has worked, new surplus means it was never commissioned, and new means no service history at all. Where a listing is silent on condition, ask, and get the answer confirmed before a price is discussed.

What emissions Tier are the engines?

The listings do not state a Tier rating, so we do not claim one. If a permit, a site owner or a client requires a particular Tier, say so when you enquire and ask for the emissions label on that specific engine to be confirmed before you commit to it.

Can I buy a diesel generator for prime power, or only standby?

Either can be bought; the question is which rating the kW figure on the listing refers to. A set's prime rating is lower than its standby rating, because prime assumes it is the main source of power, running long hours with a load that varies. If you are looking for a prime power generator for sale, ask which rating the listing shows, then size against the prime figure.

Can I see it run under load before I buy?

Ask for it when you enquire. We rent load banks as well as generators, so the set can be worked near the load you plan to put on it rather than simply started. Over the run, watch oil pressure, coolant temperature and output voltage; on a used engine those readings are the most honest part of the inspection.

Can I rent the unit first?

Check the listing. Where it shows a For Rent badge as well as For Sale, the set can go out on a rental term before you decide. Rent-to-own is a separate arrangement and applies only to units whose listing carries the Rent to Own badge.

Point to a listing, or describe the load.

If a set on this page looks right, tell us which one and we will send a written price for it. If none stands out, give us the running load, the voltage, whether the duty is standby or prime, and any emissions requirement on the site. We will match that against what is listed, and if nothing fits, we will tell you so.
