Walk-In Coolers for Florists: Temperature, Humidity and Airflow
A walk-in cooler for flowers has to control temperature without blasting petals or trapping moisture. Most cut flowers share a cool holding range, while tropicals and orchids may need a warmer zone. Titan designs floral walk-ins around the product mix, bucket workflow, humidity, air distribution and the room available in the shop.
Use product groups to set the temperature plan
FloraLife recommends 1°C to 3°C and 75% to 85% relative humidity for most cut flowers. It lists a warmer range for tropical flowers. A shop carrying both groups should not force every stem into one condition. Separate zones, a smaller dedicated room or a deliberate inventory plan can protect sensitive product.
Airflow must reach the room without striking blooms
Cold air has to circulate back to the evaporator, but direct discharge can dry or chill flowers at the front of the rack. Leave breathing room between buckets, keep tall arrangements out of the discharge path and avoid blocking the return. FloraLife specifically advises good airflow while keeping flowers and boxes away from the direct fan stream.
Humidity helps only when surfaces stay clean
Higher humidity reduces water loss, yet condensation and dirty containers increase disease risk. Stable temperature, sanitation and drainage belong in the same design. Choose food-safe interior finishes, provide space to clean around shelving and keep standing water out of the walking path.
Plan for receiving, rotation and peak days
The door, aisle and shelving must support the way staff move boxes and buckets. Map receiving space, processing benches and the first-in, first-out route. A holiday peak can double handling without changing the cooler footprint, so clearances should work when inventory is dense without choking airflow.
Measure flower operations before sizing refrigeration
Door traffic, incoming product temperature, lights, people and the surrounding shop all affect load. Share the product mix and peak inventory with the refrigeration designer. Titan builds walk-in coolers for florists and coordinates the commercial refrigeration installation. Compare enclosure options under custom walk-in coolers, then plan a floral cooler with Titan.
A floral room also needs a receiving routine. Remove field heat promptly, keep packaging from blocking airflow and separate damaged material before it affects the working stock. Record peak delivery days rather than average bucket counts. That number drives useful aisle width and temporary staging space when the cooler is busiest.

Floral cooler questions
What temperature should a florist walk-in cooler use?
FloraLife recommends 1°C to 3°C for most cut flowers, while tropical flowers need warmer storage. Follow the needs of the actual product mix.
What humidity is recommended for cut flowers?
FloraLife gives a general range of 75% to 85% relative humidity for most cut flowers.
Should flowers sit directly in front of the evaporator?
No. Maintain circulation but keep flowers and boxes away from the direct discharge air stream.
Can tropicals share the same cooler as roses?
Often not at one setting. Tropicals may need a warmer condition, so plan separation based on the varieties carried.
What layout information should a florist provide?
Provide bucket sizes, rack layout, peak inventory, receiving path, door traffic, processing workflow and product groups.
List the flower groups, bucket counts, delivery peaks and workroom route before choosing the room size. Titan can turn that operating picture into a custom floral cooler layout.
