Carey DPC-9SS Smart Canner: Same Machine as the NESCO NPC-9?
We can't confirm that the Carey DPC-9SS and the NESCO NPC-9 are the same machine. Only retailers say so. What is documented is a shared owner. A guide on NESCO's site calls Carey a trademark of The Metal Ware Corp, "parent company to NESCO." The two guides read much alike, and neither says the machines are identical.

The short answer
The DPC-9SS guide calls Carey a registered trademark of The Metal Ware Corp, parent company to NESCO. That shows a shared owner. The DPC-9SS and NPC-9 guides give the same jar counts and regulators, and neither says the machines are identical, so we leave that unconfirmed. We found no expert statement naming either machine, and we don't make it a pick.
If you own a Carey, or found one at a good price, this page sorts out what the paperwork says. The full comparison of what the sources say about electric canners is on its own page.
Who is behind the Carey name?
Guides on NESCO's site hold the answer. The DPC-9SS guide says "Carey" is a registered trademark of The Metal Ware Corp, "parent company to NESCO." The NPC-9 guide says NESCO is a registered trademark of The Metal Ware Corp. So one company stands behind both names. That is all these lines show. They don't say what is inside either machine.
"Smart canner" is a product name, not a type of machine. On our guide to electric canner types, a plug-in machine that both cooks and cans counts as a cooker and canner in one. That is different from a canning-only machine such as the Presto Precise.
How do the two guides compare?
We read both guides on November 2, 2026. Everything in this table is the maker's own statement. None of it is a safety finding.

The older September 2025 DPC-9SS guide names "Carey Customer Service" with the same phone number. The 2026 revision names NESCO Customer Service.
Why do we still say "unconfirmed"?
Matching numbers on paper are a clue, not proof. Neither guide says the two machines are the same, and we didn't compare parts, controls or software. Retailers describe the machines alike, and that is where the same-machine claim comes from. We'd rather tell you it is unconfirmed than round it up. The NESCO vs. Presto comparison shows more about how this type differs from canning-only machines.
One practical point follows. Use the guide with your own model number on its cover, and ask before you swap parts between the two. On November 2, 2026, NESCO's download page labeled one link NPC-9 while the file name read DPC-9SS. So check the cover of whatever you download. Our manuals page explains how.
What do the experts say?
Who names it. We found no statement from the National Center naming NESCO or Carey. So saying it calls this machine unsafe goes further than it has. Calling it safe skips what is missing.
What reaches it by type. Penn State's wording on combination appliances is above. The DPC-9SS guide tells you to use the USDA Complete Guide for tested recipes. The National Center does not support USDA canning instructions in electric multi-cookers. It hasn't said whether that covers this machine.
Why the jar count isn't the whole story. Holding four quart jars is only one of several conditions. It doesn't prove the heating, holding and cooling match the tested instructions. The temperature decides.
What isn't evidence here. A Utah State study covered three cookers it didn't name, so it isn't a test of this machine.
Which wording in the guide should I read slowly?
The canning sections of the 2026 DPC-9SS guide read like those of the 2026 NPC-9 guide. That includes the passages we flag on our NESCO page. The section headed high pressure canning, for example, opens with the words "low pressure canning." If a passage leaves you unsure, ask NESCO customer service at 1-800-288-4545. Ask your state's university extension office (free local food-safety advice) too. Do this before you can.
What if you own one, or are still deciding?
If you already have a Carey, keep the guide close and take your recipes from a tested source. Put your questions to customer service and your extension office. We can't give you a yes or no about your machine from what we read. We know that can feel unsatisfying. It is always fine to ask.
Carey has no listing in our Amazon data, so we don't link it. The closest machine we can show is the NESCO, with its warning.
NESCO
NESCO NPC-9
A 9.5-quart pressure cooker with a canning setting and regulator weights.
- Type
- Combination cooker-canner with regulator weights
- Pressure canning
- Yes, by NESCO's statement only
- Water bath
- Pints and smaller only, per NESCO
- Steam
- NESCO's guide has a low-pressure/steam section; this is not what the Wisconsin and NCHFP steam-canner research covered
- Liquid capacity
- 9.5 quarts
- Jars per load
- 4 wide-mouth quarts, or up to 5 pints; dry-fit first
- Altitude
- Black regulator up to 1,000 feet, green regulator above; not above 7,500 feet, per NESCO
- Price class
- Mid-range
Stated in: NESCO NPC-9 Care/Use Guide (revision of October 27, 2026), read 2 November 2026
Why here: This is the machine most readers compare the Carey with. It is not a pick for low-acid canning.
Best for: You mainly want a cooker and have read the caution. Not a pick for canning low-acid foods (vegetables, meat, chicken, fish).
- Also pressure cooks, steams and slow cooks, says NESCO
- Lower price class than the plug-in canners made just for canning
- Two regulators for two altitude ranges, says NESCO
- Penn State Extension says it cannot recommend this kind of appliance, because the research is missing
- Four wide-mouth quart jars at most. NESCO asks you to dry-fit jars first
- No quart jars in water bath, says NESCO
- NESCO advises against use above 7,500 feet
Read this first
This is a combination cooker-canner. Penn State Extension (September 13, 2024) says combination canner/cooker appliances cannot be recommended because the research on their safety is missing. Penn State names no brand; placing the NPC-9 in that group is our reading. NESCO's guide sends users to USDA's tables, and NCHFP (February 1, 2019) says it does not support USDA canning processes in electric multi-cookers. We found no agency statement that names this machine.
If your goal is low-acid foods (vegetables, meat, chicken, fish) on the shelf, we suggest a stovetop canner in the same price range. It is the type the National Center wrote its advice for. Our electric vs. stovetop comparison shows the trade-off.
Presto
Presto 23-Quart Stovetop (01781)
A pot for your stove, the kind the USDA's canning steps were written for.
- Type
- Stovetop pressure canner with dial gauge
- Pressure canning
- Yes
- Water bath
- Yes, quarts and smaller, per Presto
- Liquid capacity
- 23 quarts
- Jars per load
- 7 quarts, or 20 regular-mouth pints stacked
- Altitude
- You raise the pressure by altitude from the USDA tables. Water bath times also change with altitude.
- Price class
- Mid-range
Stated in: Presto Canner Comparison Guide (2025), read 2 November 2026
Why here: It is in the same mid-range price class. Presto says it holds 7 quart jars, and it is the type the National Center says its advice was written for.
Best for: You want to pressure can low-acid foods (vegetables, meat, chicken, fish) and can stay near the stove.
- The National Center's advice was written for stovetop canners
- Seven quart jars, or up to 20 regular-mouth pints stacked, says Presto
- Also works as a water bath canner for quarts and smaller, says Presto
- Works on gas and on electric coil and smooth-top ranges, says Presto
- You watch the gauge and adjust the heat yourself
- The dial gauge needs an accuracy test every year, says Presto
- Presto does not list induction for this pot. The 01784 is its induction version
What people ask
Is the Carey DPC-9SS the same machine as the NESCO NPC-9?
We can't confirm it. Retailers say so, and the two guides give the same jar counts, regulators and power. But neither guide says they are identical, and we didn't take the machines apart. So the same-machine claim stays unconfirmed. The shared owner is documented, through the trademark line in the DPC-9SS guide.
Who makes Carey canners?
The DPC-9SS guide says Carey is a registered trademark of The Metal Ware Corp, parent company to NESCO. The warranty in that guide comes from The Metal Ware Corporation. It sends questions to NESCO customer service at 1-800-288-4545. We found no separate Carey maker's site in what we read.
Does the Carey hold enough quart jars?
Its guide says up to 4 wide-mouth quart jars, and asks you to dry-fit your jars first, since not all will fit. Holding four quart jars is only one of several conditions. It doesn't prove the heating, holding and cooling match the tested instructions.
Do the USDA or the National Center approve the Carey canner?
They don't approve any canner. We found no statement from the National Center for Home Food Preservation naming NESCO or Carey. The guide sends you to the USDA Complete Guide for tested recipes. The National Center does not support USDA canning instructions in electric multi-cookers. Our safety page puts these statements in order.
Can I buy a Carey DPC-9SS through this site?
No. Carey has no listing in our Amazon data, so we don't link it. We show the NESCO NPC-9 with its warning, because that is the machine most readers compare it with. We show a stovetop canner in the same price range as an alternative.
