How to Choose an Undercounter Fridge That Fits Your Commercial Counter

Why Sizing Matters Before You Order

An undercounter fridge that is even 20 mm too wide, too tall, or too deep can mean a costly return, delayed service, and a gap in your cold-chain compliance. Before you commit, work through every dimension below — and use our Professional 220L 2 Sliding Glass Door Back Bar Cooler – Black (850mm Height) | BC02PS85 as a real-world reference throughout this guide.

1. Measuring the Opening: Width, Depth & Height

Width

Measure the clear internal width of the recess or counter gap at three points: front, middle, and rear. Use the smallest figure. Add at least 25 mm of clearance on each side for airflow if the unit will sit in a closed recess. The BC02PS85 has a body width of 850 mm, making it well suited to standard back-bar counter bays or island prep counters built to 900 mm modules.

Depth

Measure from the back wall to the front edge of the counter, then subtract the depth of any skirting, pipework, or cable trunking running behind the unit. Most undercounter fridges run 500–600 mm deep. Ensure the door (or drawer) can open fully without fouling adjacent equipment — see the door swing section below.

Height

Record the floor-to-underside-of-worktop dimension. Adjustable feet on commercial units typically add 10–25 mm, so deduct this from your available height. The BC02PS85 stands at 850 mm to the top of the cabinet — ideal for fitting beneath a standard 900 mm worktop with a 50 mm clearance for levelling.

Pro tip: Always measure in millimetres. Imperial conversions introduce rounding errors that can cause a unit to be millimetres too tall — enough to prevent installation.

2. Door Swing and Access Clearance

Sliding glass doors, like those on the BC02PS85, eliminate door-swing entirely — a significant advantage in tight bar runs or galley kitchens where a hinged door would block walkways or clash with the opposite counter. If you are comparing a hinged-door model, measure the full arc the door sweeps and confirm there is no fixed obstacle (column, adjacent fridge, shelving unit) within that radius.

For sliding-door models, check that the track and handle protrude no more than your front clearance allows, and that the door can slide its full width without the handle striking a wall or end panel.

3. Ventilation Requirements

Inadequate ventilation is the most common cause of undercounter fridge failure and inflated energy bills. Most commercial undercounter units are front-venting, meaning they draw cool air from the front kick-plate and exhaust warm air from the front grille. This design, used on the BC02PS85, allows the unit to be built fully into a closed recess — but the front grille must never be blocked by floor matting, decorative panels, or stored items.

  • Front-venting units: require at least 50 mm clear in front of the grille at all times.
  • Rear-venting units: require 100–150 mm clear behind the cabinet; cannot be built in flush.
  • Ambient temperature: confirm the unit's climate class (SN, N, ST, T). The BC02PS85 is rated for typical commercial environments — avoid positioning next to ovens, dishwashers, or any heat source that raises the local ambient above the rated maximum.

4. Electrical Supply

Verify the following before installation:

  • Voltage & frequency: confirm the unit matches your supply (230 V / 50 Hz for UK installations).
  • Dedicated circuit: commercial refrigeration should run on its own fused spur — do not share with high-draw appliances.
  • Cable routing: the power cable exit point (usually rear bottom) must align with your socket position without kinking or trapping the cable beneath the unit.
  • Energy consumption: check the annual kWh figure on the specification sheet and factor it into your running-cost calculations, especially if you are running multiple units.

5. Shelf Configuration and Bottle Clearance

Capacity in litres tells you the volume, but shelf pitch determines what actually fits. Key questions to ask:

  • How many adjustable shelves are included, and what is the maximum shelf pitch (height between shelves)?
  • Can shelves be removed entirely to accommodate tall bottles, kegs, or gastronorm trays?
  • What is the maximum bottle height the unit will hold with all shelves removed?

The BC02PS85's sliding glass doors provide full-width access across 220 litres of storage, with shelves designed to accommodate standard 330 ml and 750 ml bottles upright. The glass doors also allow staff to identify contents at a glance, reducing door-open time and helping maintain consistent internal temperature.

6. Pre-Purchase Checklist

Run through this checklist before placing your order:

  • ☐ Measured width, depth, and height of the recess at three points each
  • ☐ Confirmed door swing (or sliding door) does not obstruct walkways or adjacent equipment
  • ☐ Verified front grille will remain unobstructed for airflow
  • ☐ Checked climate class matches the installation environment
  • ☐ Confirmed a dedicated electrical spur is available at the correct voltage
  • ☐ Reviewed shelf pitch and bottle clearance against your product range
  • ☐ Checked the unit weight against your floor loading capacity
  • ☐ Confirmed the unit complies with any relevant food safety or environmental health requirements for your premises
