The fusionchef Diamond is a commercial grade sous vide circulator. Julabo, the manufacturer of the Diamond, is one of the global leaders in precision temperature control equipment, similar to PolyScience. They have used this experience and expertise to create a premium line of kitchen durable immersion circulators. The circulators are German designed with an exacting level of precision and durability necessary in today's culinary business.
On the face of the circulator there is a small tag which reads, "Crafted in Germany" - that says it all! When you pick this thing up, all 11 pounds (5kg), it feels like a tank. It is clear this sous vide circulator has been designed for the rigors of a restaurant or caterer kitchen. Although some of the performance parameters are quite similar to circulators designed for the home cook, there are others that clearly set this apart for commercial use.
The entire unit is built from stainless steel and the protection grid is easily removed for cleaning and maintenance of the pump and heating coil. The high-capacity pump moves the water at 3.7 gal/minute (14 l/min), which will allow container volumes up to 15.32 gal (58 l). This comes in handy if you would like to sous vide more than 60 pounds (27kg) of beef tenderloin at one time!
The Diamond is also relatively smart with 15 customizable presets and 3 timers. There are also two connections in the rear of the unit. An RS232 to a PC for control and HACCP data logging. The second connects to a core temperature sensor. Finally, the unit has ample heating power with 1200 W @115 V and 2000 W @230 V.
The unit is quite large, limiting it to use with the larger sous vide containers found in most commercial kitchens.
Their "Easy fusionchef" software provides the ability to control, visualize, and log data for up to 24 units simultaneously. It uses RS232 connections to accomplish this.
It's clear that when designing a sous vide immersion circulator for the demanding environment found in a restaurant kitchen, it would have to be more powerful and reliable than the typical home circulator, and consequently, more expensive.
If you are a chef with a restaurant or catering business that uses sous vide cooking extensively, this would be an excellent immersion circulator for your use. The machine has the power and capacity for reliably cooking large amounts of product at one time.
We would be remiss if we did not mention that we do not recommend the fusionchef Diamond circulator for the typical home cook, unless you regularly are cooking very large quantities of food.
