HETR-4 Cooler Module - fermenting, proofing, dehydrating and hot holding at homeThe HETR-4 totally rethinks a warming oven. Its groundbreaking design creates the same precision temperature range in the cooler you already own. Don’t hotwire your oven, don’t crowd your kitchen, don’t limit your cooking.
Results in baking are determined by attention to detail. The pros don’t allow for variability, you shouldn’t either.
Fermentation can be fickle, remove chance from the equation.
Preserve ingredients for storage, concentrate flavors for an experimental dish, and eliminate another piece of equipment from your kitchen.
Whether you’re a caterer serving in the field or a backyard pitmaster resting brisket overnight, don’t risk cold food. Or, explore the new field of vegetable blackening, starting with garlic.
±0.5°F anywhere from 70°F to 150°F, a configurable moisture pan, and 30 CFM of managed air flow. Once you set your target, the HETR-4 maintains your conditions indefinitely.
No permanent footprint required. The HETR-4 is designed to fit common household storage. When a project’s done the whole system goes in a drawer and your cooler goes back to hauling ice.
The HETR-4 is designed to be compatible with many coolers. We’ve also built an entire ecosystem of accessories and add-ons so you can optimize it for how you use it.
Every review here comes from a HETR-4 owner. A few weeks after your order arrives, we’ll email to ask how it’s going.
Our cooler simulator predicts HETR-4 performance in any cooler - the temperature range you can hold, and how long it takes to get there. Drop your email and we’ll send it over.
