I love Samsung refrigerators. They are very well built and perform great, at a much lower price than the sub-zero.

There are many commercial brands of fridges, I always check out AJ Madison when looking for appliances.

Commercial refrigerators are NOISY and not at all energy efficient. They are also sparse and utilitarian in the interior. None of the consumer conveniences like bins and shelves. But, you may be used to a expensive deafening noise if you have the required commercial ventilation and make up air for the asphyxiation inducing cooking thing that you have planned.
