TRAVERSE CITY, Mich. — DC Norris North America, a leader in the commercial and industrial food processing equipment industry, is proud to announce that its flagship commercial sous vide cook tank, the CT-1, has been officially approved by the International Sous Vide Association (ISVA). This prestigious approval underscores the CT-1’s exceptional performance and adherence to the highest standards in sous vide cooking. The CT-1 by DC Norris North America is the only commercial-scale sous vide cook tank to receive the ISVA’s approval.

The ISVA device approval process rigorously tested the CT-1 on four critical criteria for optimal performance in a commercial sous vide tank: temperature stability, accuracy, uniformity, and recovery time.

Temperature Stability: The ISVA praised the CT-1 for its impressive temperature stability, maintaining a variance within 0.25ºF – 0.35ºF during extensive test periods at both 131ºF and 180ºF. “The CT-1 surpassed our expectations,” commented Mike La Charite, ISVA CEO.

Temperature Accuracy: The CT-1 excelled by maintaining temperatures within an extraordinary 0.03ºF – 0.34ºF of the set temperature consistently, far surpassing the acceptable variance of 1ºF.

Uniformity and Recovery Time: The ISVA’s certification trials highlighted the CT-1’s outstanding uniformity in temperature distribution. Even during heating processes, where variability is expected, the CT-1 showed minimal variation. “We were delighted by the CT-1’s uniformity,” La Charite noted. “The temperature difference across different probes rarely exceeded 0.2ºF for lower temperatures and 0.4ºF for higher temperatures.”

In the recovery time tests, the CT-1 demonstrated the capability to efficiently heat products, significantly surpassing food safety guidelines and streamlining kitchen operations.

In addition to the ISVA approval, the CT-1 is NSF Certified and is designed, manufactured, and shipped from the United States. Among its many outstanding features, the CT-1 requires no minimum batch size and is designed to be “plug and play” for commercial operators utilizing standard electric heating and requiring no hood system. The CT-1’s data recording feature is a standout – making regulatory compliance simple and ensuring food safety.
