Floral Cooler Doors for Walk-In Cold Storage

Floral coolers are typically maintained between 34°F and 38°F (1°C to 3°C) — cold enough to slow flower deterioration without freezing petals. The exact setpoint depends on flower variety; tropical flowers prefer slightly warmer temps around 50–55°F. ELT's cooler doors are rated for standard cooler-duty applications in this temperature range.

Most cut flowers last 5 to 14 days in a properly maintained floral cooler, compared to 2 to 4 days at room temperature. Roses, lilies, and carnations can last up to 2 weeks. A well-sealed, energy-efficient cooler door is critical — air leaks raise temperature, accelerate respiration, and shorten flower life significantly.

Standard floral cooler doors range from 30"x78" to 60"x84" for swing-style walk-in applications. ELT Custom Coolers stocks 65 prehung replacement door sizes and offers custom sizing at no upcharge. For wide-opening floral distribution rooms, sliding doors from 36"x78" up to 12'x12' are also available. Measure your rough opening width and height before ordering.

Yes. ELT's prehung replacement doors with plug or jamb frames are designed for drop-in installation over existing walk-in cooler wall panels — no panel replacement required. Most standard-size swing door swaps take approximately one hour, minimizing cooler downtime. Custom sizes are available for non-standard openings with same-business-day quotes.

Yes. ELT prehung cooler doors ship with NSF-approved chrome hardware including a lockable latch with interior safety release, door closer, cam-rise hinges, magnetic door gasket, and aluminum kick plates. Additional hardware accessories — including Kason hydraulic door closers, handles, and safety glow inside release handles — are also available separately.

Absolutely. PVC strip curtains like the Kason 402 Easimount act as a secondary barrier when the main cooler door is open during deliveries or high-traffic periods. They reduce cold-air loss, cut compressor run-time by 20–40%, and help maintain the stable temperature and humidity levels that fresh flowers require. They are easy to install and replace without tools.
