Undercounter refrigerators typically operate between 33°F to 41°F, while undercounter freezers maintain temperatures between -10°F to 0°F.

Blast Chillers

Blast chillers are specialized units designed to rapidly cool hot food to safe storage temperatures. This helps preserve food quality and reduces the risk of bacterial growth. Blast chillers can cool food from 160°F to 40°F in just a few hours, making them an invaluable tool for busy kitchens.

Refrigerated Prep Tables

Refrigerated prep tables are a multitasking marvel, combining refrigeration with a work surface. They’re perfect for keeping ingredients like sandwich toppings or pizza ingredients cold and within easy reach. Refrigerated prep tables typically maintain temperatures between 33°F to 41°F.

Bar Refrigeration

For those managing bars or beverage services, specialized bar refrigeration units are a must. These include back bar coolers, underbar refrigerators, and glass frosters. They ensure that beverages are kept at optimal serving temperatures, enhancing the overall customer experience.

Think about it—everything from your craft beer to your signature cocktails relies on precise temperature control. Let’s face it, who wants a lukewarm beer on a hot Nashville night?

Choosing the Right Commercial Refrigeration System

Selecting the right commercial refrigeration system for your kitchen depends on several factors. Here are some key considerations to keep in mind:

Size and Capacity

The size and capacity of your refrigeration system should be tailored to your kitchen’s needs. Consider the volume of food you need to store, as well as the physical space available in your kitchen. Is this the best approach? Let’s consider the following:
