Commercial flower cold room with rolling racks and cut flowers
Commercial Flower Cold Storage

Flower Cold Rooms Built Around Your Product Load

We design modular storage, pre-cooling and multi-zone rooms for growers, wholesalers, exporters and contractors. Every proposal starts with product and operating data—not room volume alone.

Recommended Storage Conditions for Common Flowers

Proper storage extends vase life, maintains quality and reduces postharvest losses.

Flower TypeTemperature (°C)RH (Relative Humidity)Notes
Rose1–4°C85–95%Store dry. Use fresh-cut flower food after conditioning.
Carnation0–2°C80–90%Store dry. Sensitive to ethylene—keep away from ripening produce.
Chrysanthemum1–3°C85–95%Store dry. Ensure good air circulation to prevent Botrytis.
Lily2–4°C80–90%Store dry. Some varieties are ethylene sensitive.
Orchid13–15°C70–80%Store in well-ventilated conditions. Avoid temperatures below 10°C.
Tropical Flowers10–13°C75–85%Store dry. Sensitive to chilling—avoid temperatures below 10°C.
Best Practices
  • Pre-cool flowers before storage
  • Maintain consistent temperature
  • Ensure proper airflow
  • Monitor and calibrate equipment regularly

Note: Conditions may vary by variety and maturity stage. Follow specific grower recommendations when available.

What serious B2B projects must address

The thermostat tells only part of the story.

01

Holding vs. pull-down load

Holding at 2°C differs greatly from cooling 2,000 kg from 18°C to 2°C in six hours.

02

Humidity as a system

Coil temperature, fans, packaging, doors and defrost affect RH. A humidifier cannot correct poor design.

03

Airflow and rack clearance

Direct air increases moisture loss; weak circulation creates hot spots. Both need engineered airflow paths.

04

Net usable capacity

We calculate carts, boxes or pallets after allowing for aisles, doors and airflow space.

05

Performance definition

Controller accuracy does not equal room uniformity. Define sensors, alarms and commissioning checks.

06

Climate and failure risk

For up to 45°C design ambient, review condenser duty, protection, alarms and standby capacity.

Heat-load based selection

Turn operating data into an installation-ready solution.

We combine transmission, pull-down, infiltration, internal and ambient loads to define capacity, evaporator duty and controls.

Buyer questions

Flower Cold Room FAQ

1. What temperature should a flower cold room maintain?

Many non-tropical flowers use 0–2°C; cold-sensitive tropical varieties often need 8–13°C.

2. What relative humidity do flowers require?

Many temperate cut flowers use 90–95% RH; species, packaging and holding time change the target.

3. Can different flowers share one room?

Combine only crops with compatible temperature, RH, chilling and ethylene requirements.

4. Do I need holding storage or pre-cooling?

Pre-cool warm incoming flowers; use holding rooms for already-cooled products.

5. How do you calculate refrigeration capacity?

We calculate transmission, product, infiltration, internal and ambient loads—not volume alone.

6. Will airflow dehydrate the flowers?

Correct evaporator position, air throw and rack clearance limit direct drying.

7. Does every room need a humidifier?

No. Coil design, packaging, door activity and climate determine the need.

8. Can the system handle hot climates or unstable power?

High-ambient condensers, voltage protection, alarms and standby capacity address these risks.

9. What does the package include?

The final BOM identifies panels, refrigeration equipment, controls, accessories and drawings.

10. What information do you need for a quotation?

Send dimensions, flower list, packaging, kg/day, entry and target temperatures, pull-down time, door activity, location and power supply.
