Sous-vide is no longer just a high-end trend — it’s become a must-have cooking method for hotels, restaurants, and caterers looking to deliver consistency, efficiency, and unforgettable flavor. But if you’re shopping for sous-vide equipment, you’ll quickly notice there are two main types of machines: immersion thermocirculators and statically heated tanks.

Each has its strengths, and the right choice depends on the size of your operation, your menu style, and the level of precision you require.

Immersion Thermocirculators: For Precision-Driven Chefs

Immersion thermocirculators are compact “sticks” that heat and circulate water in an external tank. Thanks to advanced electronics and a built-in motor, they maintain precise, uniform temperatures throughout the cooking bath.

For professional chefs who demand accuracy down to tenths of a degree, thermocirculators are the gold standard. High-end models, like Sirman’s Softcooker Wi-Food, even connect to apps, letting you monitor and control the cooking process remotely from a mobile device. Smart software also manages power interruptions — ensuring your dishes are never compromised.

⚡ Pro Tip: Look for models with at least 1200 Watts of power. That’s the level needed to handle the water volume of most professional kitchens.

Statically Heated Tanks: Reliable, Budget-Friendly Performance

Static tank sous-vide machines combine the heater and tank into one unit. While they may not match the micro-precision of thermocirculators, they still deliver reliable results — making them a popular mid-range choice.

For smaller kitchens, boutique restaurants, or catering setups, these machines strike a balance between cost and performance. Models in Sirman’s XP and Wi-Food ranges are excellent examples of how static tanks have evolved with more user-friendly features.

Don’t Forget the Essentials: Vacuum Sealers & Bags

Sous-vide doesn’t stop at the water bath — it starts with vacuum sealing. Chamber vacuum sealers are the top choice for professionals because they create a near-complete vacuum, ensuring food is safely sealed. Pair them with plain, heat-resistant bags designed for long cooking times.

If you need to seal liquids regularly, a vertical chamber model is ideal to minimize spillage.

And for smaller businesses looking to save space, there are hybrid solutions like Easysoft — a clever all-in-one unit that combines vacuum sealing and sous-vide cooking in one compact machine.

Which Machine is Right for You?

Choose Immersion Thermocirculators if you need precision, scalability, and advanced features.

Choose Statically Heated Tanks if you’re running a smaller operation and want reliability without stretching your budget.

Don’t overlook the importance of the right vacuum sealer and bags — they’re just as essential as the cooker itself.
