NEW - Commercial Production Tanks
We are thrilled to announce the approval of our first commercial sous vide tank! With help from our committee, we came up with a stringent set of criteria to ensure food safety and efficiency as detailed below.
Temperature Accuracy
Maintains accuracy from 68ºF to 180ºF within 1ºF/0.5ºC
Temperature Stability
Maintains stability within 1ºF / 0.5ºC over 15 minute time period (tested at 131ºF and 180ºF)
Temperature Uniformity
Maintains uniformity in the bath within 1ºF/0.5ºC
Recovery Time
At full capacity and bath at 131ºF, brings cold product introduced into the bath from 41F to 130F core within 1.25 hour for 1” or 2 hours for 1.5”

The DC Norris CT-1 surpassed expectations for all of these criteria.
Temperature Stability: The CT-1 maintained a stability well within 0.25ºF – 0.35ºF during the 15-minute test periods at both 131ºF and 180ºF.
Temperature Accuracy: With the temperature offset properly calibrated, the CT-1 maintained temperatures within 0.03ºF – 0.34ºF of the set temperature at all times.
Temperature Uniformity: The temperature difference across the four probes was well within limits, rarely exceeding 0.2ºF for lower temperatures and 0.4ºF for higher temperatures.
Recovery Time: When adding 100 lbs of cold product, the water reached the set temperature in 31 minutes. Further, the 1.5" thick New York Strip steaks reached equilibrium in just 1 hour and 20 minutes.
