The Sansaire is an immersion circulator: it houses the heating coils, thermometer, microcontroller and water-circulating motor that work together to maintain a precise temperature in your water bath. Unlike some other sous vide machines, which have a fixed-size water bath, or require you to use your own rice cooker or crock pot, the Sansaire circulator works with any container. Just making a few eggs for breakfast? Attach the Sansaire to a small saucepan, and you’re ready to cook! Cooking racks of ribs for a crowd? No problem – the Sansaire will heat and circulate up to 6 gallons of water in a large basin!
