Dry-aging cabinet specs: humidity, capacity, temperature and voltage

The catalog files every product under one of 4 types: large cabinets (13), home cabinets (12), dry-aging bags (10) and countertop cabinets (1). Countertop cabinets sit on a counter and hold a primal or two. Home cabinets are fridge-sized, freestanding or under a counter. Large cabinets have a stated load over 100 lb or over 300 litres, and most stand full height.

Bags are not an appliance at all: a membrane permeable to water vapor that wraps a cut so it can age in an ordinary refrigerator. Cabinet, bags or a spare fridge.

Much of the dry-aging market is European and commercial equipment built for 220–240 V. Importers resell it to US buyers, and a 230 V cabinet cannot run from a standard US outlet without a transformer. Those cabinets are not listed here at all.

Of the 26 cabinets that are listed, 12 have a maker-stated voltage in the 110–120 V range (3 of them are sold in both a US and an EU version, and the US one is what is listed). The other 14 are sold on US stores without a voltage figure on the maker’s page; their pages say “not published” rather than assume 120 V.

A 2016 review of the research (Dashdorj et al.) reports that dry aging is done at 0.5–4 °C, about 33–39 °F. A cabinet’s top setting often goes far higher, because makers also list modes such as cheese or charcuterie fermenting. That warmer end is not a setting for beef.

Of the 23 cabinets here that publish a range, 23 can be set to 39 °F or colder. The median lowest setting is 34 °F; the coldest is 32 °F on the DRY AGER UX 750 PRO S and 4 others.

Humidity is what separates a dry-aging cabinet from a refrigerator with a fan, and it is the claim listings stretch most. Too humid and the surface stays wet; too dry and the meat loses more weight and grows a thicker crust to trim. The review reports 61–85% relative humidity. Each cabinet here is filed at one of four levels, by what its maker describes:

• Active (17 cabinets): a humidifier and/or dehumidifier holds a set-point you choose. 14 publish the adjustable range, for example 40–90% on the DRY AGER UX 750 PRO S.
• Fixed (6): a built-in humidifier holds one level the maker sets, and you cannot change it. The SteakAger PRO 20: built-in humidifier, fixed at 75%.
• Passive (2): a salt block, a water tray or airflow alone, with no set-point. The Steak Locker Studio is one.
• None (0): the maker claims nothing about humidity.

A hygrometer readout does not make a cabinet active; it only tells you the number. For 1 cabinet, the maker’s page does not say which it is, and the listing says so.

The litre figure on a spec sheet is the inside of the box. How much meat it ages is smaller, because air has to move all the way around each piece. So the figure compared here is the maker’s own stated maximum meat load, converted to pounds where it is given in kilograms. 20 of 26 cabinets state one; the rest show “not published”.

Among the 19 cabinets that publish both, the stated load runs from 0.29 to 1.52 lb per litre, which is why a volume figure cannot stand in for a load figure.

Stated loads here run from 20 lb to 350 lb (the Steak Locker Professional Edition G5). Divided into list price, that is a median $26 per pound of capacity, lowest on the VEVOR 232 LBS Dry Aging Fridge at about $5. How much of that load you eat.

A cabinet built into a cut-out still has to shed its heat. Some vent from the front and are rated for zero clearance; others, DRY AGER’s among them, need ventilation shafts beside or behind the unit, and a rear-venting cabinet pushed into a tight cut-out traps its own heat. 18 cabinets here are sold for built-in installation and 2 are countertop units. Before buying for a cut-out, check the maker’s install sheet for the gaps it needs, not just the cabinet’s outside size.

21 cabinets have a UV lamp inside, which their makers fit as a sanitizing measure; what it achieves is the maker’s claim, not something this site has measured. A UV-protected glass door is a different thing: it blocks light coming in rather than adding any.

6 cabinets have an activated-carbon filter on the air path. Makers fit it for odor: aging beef smells, and a filter keeps that smell in the box and out of the room.

1 cabinet comes with a Himalayan salt block and 5 offer one as an extra. Makers attribute various effects to it. A salt block does not hold a humidity set-point, which is why a cabinet whose only humidity measure is a salt block is filed as passive.

10 cabinets have a maker app. Apps differ more than the word suggests: some only send an alert, others change the set-point remotely or keep a log. For the Steak Locker Home Edition G5, its maker describes: “G5 Smart App over home Wi-Fi (iOS live; Android listed as coming soon on the homepage): live status, inventory tracking, and remote adjustment of temperature, humidity, airflow and UV; predictive-maintenance features listed for September 2026”.

10 bag packs are listed. Bags are single-use, so the comparable figure is the price per bag: from about $5.32 (the UMAi Dry Bulk Small Dry Aging Bags) to $11.63 (the DryAgeBags Dry Aging Bags Large 12x24 in Kit). Each maker also sizes its bags for a largest cut, shown on the page.

Sealing matters for how the membrane contacts the meat. 0 packs here call for a vacuum sealer, 9 recommend one, and 1 says none is needed.

24 products here have a published standard US warranty, longest 3 years on the DRY AGER UX 750 PRO S and 4 others. Each page quotes the warranty in the maker’s words, including any split between parts and the compressor. 8 cabinets state a US safety or food-equipment listing (UL, ETL, NSF or CSA).
