Diamond BM-15 Electric Bain Marie Tank, 4 x 1/1 GN

As a bain marie tank, this one is built around an AISI 304 structure sized for gastronorm trays up to 150mm deep (fitting an intermediate shelf isn't recommended). It draws 3000W, weighs 180 kg, and runs from +70°C to +85°C. It is from Diamond and is backed by a 1-year parts only warranty. It's specified to be worked, not just photographed. That combination of real spec and honest build is what earns it a place on a working line. Getting the size and spec right for the job in hand, rather than just going by price, tends to pay off long-term.
