What is the difference between a consumer brand refrigerator and a Commercial UL Listed refrigerator such as Marvels?
There are many differences to consider when comparing a refrigerator intended for residential use to a commercial or laboratory refrigerator. In household refrigeration models, maintaining an exact temperature is not critical and models are subject to energy consumption standards. Mechanical systems and thermostats are designed for optimum electrical efficiency, often at the expense of cooling performance under heavy use conditions. In commercial refrigeration models, cooling performance is most important. Maintaining critical temperatures for stored commodities under heavy use conditions is a requirement. For this reason, energy consumption standards do not apply to commercial models which feature larger, more powerful mechanical systems and more sensitive controls. These features are required to maintain critical storage temperatures under conditions of frequent door opening, and to quickly cool large volumes of warm commodities when they are placed in the refrigerator.
