Commercial equipment is the back-of-house gear that runs restaurants, kitchens, and storefronts — ranges, fryers, refrigeration and walk-ins, dishwashers, prep tables, sinks, and display cases. Restaurateurs, caterers, food trucks, and shop owners buy and sell as concepts open, change, or close. Buying used, check that refrigeration holds temperature and the compressor sounds healthy, look for NSF marking where it matters for inspection, confirm the gas or electric hookup matches your space, and factor in cleaning. Equipment from a closed restaurant is often nearly new at a deep discount. Because you meet in person, you can plug it in, listen to the compressor, and measure the doorway before you haul it. New Jersey's restaurant turnover keeps this category well stocked year-round.
