A countertop food warmer keeps cooked food hot in steam table pans so you can serve it without firing up a full steam table. The choice comes down to three heat types (wet, dry and induction), the pan sizes you already own, and the outlet you plan to plug into.
What a countertop food warmer does (and does not do)
A warmer is a holding tool. Nemco’s operations manual for its 6055A countertop warmers says the unit “is intended to hold containers of previously cooked, hot food at the proper temperature,” and its troubleshooting table adds that food “must be heated to safe temperatures prior to putting in warmer.” Cook or reheat first, then move the pan to the warmer.
The FDA Food Code 2022 sets the numbers. Section 3-501.16 says hot held food must stay at 135 F or above (certain roasts may be held at 130 F). Section 3-403.11 says food that was cooked, cooled and then reheated for hot holding must reach at least 165 F for 15 seconds, and the time it spends between 41 F and that target may not exceed 2 hours. Your local health department adopts its own version of the code, so confirm the rule that applies to you, and check food with a probe thermometer rather than trusting the dial.
Wet vs dry food warmer vs induction
| Type | How it heats | Good for | Watch out for |
|---|---|---|---|
| Wet (water bath) | Element heats a shallow layer of water under the pan | Sauces, rice, vegetables, casseroles, anything that dries out | Refilling water, scale buildup, preheat time |
| Dry | Element heats the well or a flat shelf directly | Fried or crisp items, plated or boxed food, quick setup | Moist foods can dry or scorch at the edges |
| Induction | Magnetic field heats an induction ready pan | Buffets and lines that want no water and no drains | Needs compatible pans and, on our listings, a drop in cutout |
Wet warmers: the classic steam table setup
Nemco’s manual for the 6055A family tells operators to fill the well with about 1/2 inch of water, preheat with a pan or cover on top (about 15 minutes with hot water, 20 with cold), and never run the unit dry. It states wet operation “is necessary to maintain safe food temperatures” for even heat. Expect to top up hot water during service.
On our store, the Nemco 6055A full size pan food warmer is listed at 1,200 watts on 120 V with a NEMA 5-15P plug and accepts one 12 x 20 in full size pan or fractional pans. If you want four separate items, the Nemco 6055A-43 countertop warmer holds four 1/3 size pans and is listed at 1,500 watts, 12.5 amps, 120 V. Nemco’s countertop warmers page lists the same wattages and a footprint of 14 5/8 x 30 5/8 in for the 4/3 model.
For soups, cheese sauce and chili, a round well works better than a rectangular pan. The Nemco 6110A-ICL is a 4 quart single well listed at 350 watts, and the Nemco 6120A-ICL twin well has two independently controlled wells at 700 watts total. Both listings say they ship with inset, cover and ladle.
Dry warmers: no water, faster setup
A dry warmer heats the surface under the pan. The Cadco WTRT-10-HD warming shelf has a 19 x 11 in stainless surface, a rolltop lid and a thermostat range of 155 to 205 F, at 300 watts on 120 V. Cadco’s own product page says it fits one full size steam pan. We list it at $428.19.
Some units let you switch between dry and moist holding. The Nemco 6070-TF hot hold dry/moist warmer uses reversible humidity control inserts, takes two 2 1/2 in deep and two 4 in deep pans (pans not included), and is listed at 900 watts, 7.5 amps, 120 V.
Induction food warmer: waterless holding
CookTek describes its SinAqua induction warmers as a waterless design with “no water or drains needed,” automatic pan detection, and four preset temperatures. Rectangular versions come in 2.5, 4 and 6 in depths, and the sensor count decides whether the well can take two halves, three thirds or six sixths.
The CookTek warmers we carry are drop in units, not countertop. The CookTek 638101 is a 6 in deep rectangular well for one full or three 1/3 pans, listed at 1,800 watts with a NEMA 5-15P plug, and the CookTek 663601 is an 11 1/4 in round well. Our 663601 listing does not state wattage, so call 866-777-2590 to confirm before you size a circuit.
Steam table pan sizes and depths
Almost every warmer here is built around the 12 x 20 in full size pan, which Nemco names as the 6055A’s opening. Fractional pans divide that footprint. Our Cadco pan listings give real numbers you can plan with:
- Full size: 12 x 20 in footprint, one per full size well.
- Half size: the Cadco SPL-2P measures 12 7/8 x 10 1/2 in, 2 1/2 in deep, 4.3 quarts, with a clear lid.
- Third size: the Cadco SPL-3P measures 12 7/8 x 7 in, 2 1/2 in deep, 2.6 quarts, with a clear lid.
- Depths: 2 1/2, 4 and 6 in are the depths that show up across these listings and CookTek’s well options.
Shallow 2 1/2 in pans suit sides you refill often; deeper pans hold more but heat through more slowly. Match pan depth to well depth.
Countertop vs drop in
A countertop unit plugs in and moves wherever you need it: catering, a pop up line, or extra capacity on a busy night. A drop in well goes into a counter cutout and usually has a remote control panel, which the CookTek listings describe. Drop in frees counter space but needs an installer and a fixed outlet. If you also hold cold items on the same line, our drop in cold food well guide covers that side. For plated food at the pass rather than pans, see our food heat lamp guide.
Wattage, voltage and lids
Most countertop warmers here run on 120 V with a NEMA 5-15P plug, but check amps. Our estimate: two 6055A-43 units at 12.5 amps each add up to 25 amps, well beyond one standard 15 amp circuit, so spread units across circuits and ask an electrician if you are unsure. Some models come in 208 to 240 V versions with a different plug, such as the CookTek 665101 on a NEMA 6-20P.
Use lids. Nemco’s manual says insets “must be covered to maintain temperatures when food is not being served.” Clear lids, like those on the Cadco SPL pans, let guests see the food.

Frequently asked questions
What temperature should a countertop food warmer hold?
The FDA Food Code 2022 requires hot held food at 135 F or above, with a 130 F exception for certain roasts. Check the food itself with a thermometer and follow your local health department’s adopted code.
Can I reheat cold food in a food pan warmer?
Nemco says its warmers are for holding previously cooked hot food, and food must be heated to safe temperatures first. The Food Code requires reheated food to reach 165 F for 15 seconds within 2 hours, so reheat on a cooking appliance.
Wet vs dry food warmer: which is better?
Wet warmers give gentler, more even heat for moist foods and sauces. Dry warmers set up faster and suit crisp items. Nemco’s 6055A models are designed for wet operation only, so do not run them dry.
Do induction food warmers need special pans?
Yes. Induction only heats compatible pans, and the CookTek units on our store detect the pan before they energize. Confirm your pans are induction ready.
Which steam table pan sizes fit a full size warmer?
A full size well takes one 12 x 20 in pan, two halves or three thirds, as the Cadco PS-TBS-HD pan holder listing describes. Questions on a specific model? Call 866-777-2590, Monday to Friday, 9AM to 6PM PST.
