Blue Air BBB90-4SG-HC 90" Three-Section Glass Door Back Bar Cooler, 31.6 cu. ft.
Blue Air BBB90-4SG-HC — 90" Three-Section Glass Door Back Bar Cooler
The Blue Air Commercial Refrigeration BBB90-4SG-HC is the largest cabinet Blue Air builds in its glass door back bar line — 90-3/8" of stainless steel carrying 31.6 cu. ft. behind three locking double-pane glass doors. Six adjustable shelves split that volume across three independent sections, so beer, mixers and wine each get their own lit bay instead of competing for one crowded box. A single side-mounted 3/8 HP R-290 system holds the whole run at 33°F to 39°F on one 115V, 3.5-amp circuit.
Key Features of the BBB90-4SG-HC
Going from a two- or three-foot back bar box to a full 90" run changes what you should be looking at — loading pattern, how one compressor covers three sections, and what the extra length costs you in floor space and power.
The Widest Box in the BBB Range
At 90-3/8" long the BBB90-4SG-HC replaces roughly four 23" single-section coolers or a 59" plus a 23" pair, and it does it on one plug and one compressor instead of two or three. Depth is 27-1/8" and height is 37", the same slim profile the 59" and 69" cabinets use, so a full-length run still tucks into a standard back bar well without pushing out into the bartender's aisle.
Three Locking Double-Pane Glass Doors
Each of the three hinged doors is glazed with double-pane glass and locks, so a 90" wall of product stays visible to guests during service and secured after close. Blue Air's hot gas frame heating system routes warm refrigerant through the door frames to control condensation rather than drawing power for an electric heater, and each gasket is a durable, easy-replacement part on a cabinet that sees three doors' worth of pull rate.
31.6 cu. ft. on Six Adjustable Shelves
Two adjustable shelves per section give you six in total, and the interior height is specified to stack three "tall boy" beers upright — so 16 oz cans load three-high in every bay instead of lying flat. Because the sections are shelved independently you can run cans in one, longnecks in the second and 750 ml wine standing in the third, then re-split the layout when your list changes.
Front-Breathing Side-Mounted Condensing Unit
The 3/8 HP self-contained system sits at the side of the cabinet and breathes from the front, which is what lets a 90" unit slot into a tight back bar and still be serviced without pulling it away from the wall. The condensing unit slides out for maintenance, defrost is automatic, and the evaporator is epoxy coated to resist the corrosion that citrus, beer and nightly spillage cause behind a bar.
R-290 on a Single 3.5-Amp Circuit
One 3/8 HP R-290 hydrocarbon system cools all three sections and draws only 3.5 amps at 115V/60Hz single phase through a NEMA 5-15P plug — the same electrical load the 59" and 69" cabinets carry, spread over far more product. Blue Air states R-290 raises energy efficiency by up to 25% versus HFC refrigerants with no ozone-depletion potential, and high-density foamed-in-place polyurethane insulation keeps the long box stable through a busy night of door openings.
Lit, Wipe-Clean Stainless Merchandising Wall
Interior LED lighting runs the length of the cabinet so labels read through the glass in a dim room without adding the heat load a fluorescent tube puts back in the box. The top and exterior are stainless steel and the interior is galvanized steel with a stainless steel floor, and the unit is ETL-Sanitation listed and NSF/ANSI Standard 7 compliant for front-of-house service.
Measuring a 90" run into your back bar: plan the opening around 90-3/8" W x 27-1/8" D x 37" H and add clearance for three door swings across the front — this is a long cabinet, and a corner or a post that clips the end door will cost you a whole section. The unit ships at 364 lbs and weighs 331 lbs empty, so confirm your floor path and door widths before delivery; 6" legs are the available leg option on this model, and casters are standard only on the 23" BBB23 cabinet.
Ideal Applications
A 90" three-section cooler is a whole back bar wall in one piece, which suits high-volume rooms that would otherwise be chaining smaller boxes together.

Frequently Asked Questions
How many doors and shelves does the Blue Air BBB90-4SG-HC have?
The BBB90-4SG-HC is a three-section cabinet with three hinged double-pane glass doors, all of them locking, and six adjustable shelves — two per section. Despite the "4" in the model number, Blue Air's own specification table and the product listing both rate this 90-3/8" cabinet at three doors and six shelves.
How much product will 31.6 cu. ft. actually hold?
Blue Air rates the cabinet at 31.6 cu. ft., the largest in its glass door back bar range and roughly four times the 7.9 cu. ft. of the 23" BBB23 single-section model. Interior height is specified to stack three "tall boy" beers, so 16 oz cans go in upright three-high across all six shelves rather than lying flat.
What space and clearances does a 90" back bar cooler need?
The cabinet measures 90-3/8" wide, 27-1/8" deep and 37" high, so you need a continuous 90-3/8" opening plus room for three doors to swing at the front. Because the condensing unit is side mounted and front breathing, it does not need rear air clearance and can be serviced in place without pulling the unit out of the back bar.
Does one compressor cool all three sections?
Yes — a single side-mounted 3/8 HP self-contained system running R-290 hydrocarbon refrigerant maintains 33°F to 39°F across the full 90-3/8" cabinet, with automatic defrost and an epoxy coated evaporator. That is the same 3/8 HP rating used on the 59" and 69" models, so you gain capacity without adding a second refrigeration system to maintain.
What electrical connection does the BBB90-4SG-HC require?
It runs on a standard 115V/60Hz single-phase circuit and draws just 3.5 amps, terminating in a NEMA 5-15P plug on a 9.8 ft (3 m) flexible three-wire cord. One ordinary bar-side receptacle powers the entire three-section run, which is a real advantage where back bar circuits are limited.
Is the BBB90-4SG-HC suitable for front-of-house service?
It is built for it: stainless steel top and exterior, a galvanized steel interior with a stainless steel floor, interior LED lighting behind double-pane glass, and ETL-Sanitation listing with NSF/ANSI Standard 7 compliance. Locking doors let you secure 31.6 cu. ft. of inventory at close, and the 37" height finishes neatly against typical back bar millwork.
