Not every commercial refrigerator does the same job. Reach-ins, undercounters, worktop units, and glass-door merchandisers each solve a different storage or merchandising problem, and picking the wrong type wastes floor space, energy, and money. Here’s how to match the right type of commercial refrigerator to the way your kitchen actually works.
The Main Types of Commercial Refrigerators
Reach-In Refrigerators
Upright units with one to three solid or glass doors. The workhorse of most kitchens — easy access, standard footprint, available in a wide range of capacities.
Undercounter Refrigerators
Low-profile units that fit beneath prep counters, ideal for tight kitchens that need cold storage close to the line without sacrificing counter space.
Worktop Refrigerators
Combine refrigerated storage with a usable stainless steel work surface on top — a space-saving choice for small prep areas.
Glass-Door Merchandisers
Designed for visibility and self-service, these units showcase beverages, desserts, or grab-and-go items to customers.
Blast Chillers
Rapidly bring hot food down to safe holding temperatures, critical for food safety compliance and batch cooking operations.
Specialty & Pass-Through Units
Built for specific workflows — pass-through refrigerators between kitchen and service areas, or specialty units sized for bakery sheet pans and bar bottles.
How to Choose the Right Type
| If your priority is… | Consider |
|---|---|
| Maximum general-purpose storage | Reach-in refrigerator |
| Cold storage right at the prep line | Undercounter or worktop unit |
| Customer-facing product display | Glass-door merchandiser |
| Rapid cooling for food safety compliance | Blast chiller |
| Moving food between kitchen and service | Pass-through refrigerator |
Sizing and Placement Tips
- Measure doorways and hallways, not just the final placement spot — reach-ins are heavier and bulkier than they look on a spec sheet.
- Leave manufacturer-specified clearance around the compressor for airflow; poor ventilation shortens compressor life.
- Match voltage and plug type to your kitchen’s electrical setup before you buy, especially for used or auction equipment.
- Consider door swing direction relative to your workflow to avoid traffic bottlenecks.
- For glass-door units, factor in additional heat load from lighting and glass when placing them near HVAC-sensitive areas.
New vs. Used Commercial Refrigeration
Commercial refrigerators are a proven category for buying used or at auction — compressors and cabinets from major manufacturers are built to withstand years of daily commercial use. Inspecting door gaskets, listening for compressor cycling, and checking interior temperature logs are the fastest ways to evaluate a used unit’s condition before bidding.
What’s the difference between a reach-in and an undercounter refrigerator?
Reach-ins are full-height upright units offering the most storage volume, while undercounters are low-profile units that fit beneath a counter or prep station, trading capacity for a smaller footprint.
How many doors do I need on a reach-in refrigerator?
Most small kitchens do well with a two-door reach-in, while higher-volume operations often need a three-door unit to keep proteins, produce, and dairy properly separated.
Are glass-door refrigerators less efficient than solid-door units?
Glass-door units typically run slightly less efficiently due to heat transfer through the glass, but modern insulated glass and LED lighting have narrowed that gap considerably.
Can I buy commercial refrigeration equipment used?
Yes — commercial refrigeration is one of the most reliable categories to buy used, especially from reputable brands, as long as the compressor and gaskets are inspected before purchase.
