China cold storage solution provider
Keeping flowers fresh for longer periods is essential for florists, flower farms, and distributors. A well-designed flower cold storage system not only helps maintain freshness and appearance but also reduces product loss and improves profitability. Below, Haocool engineers answer some of the most common questions about flower cold storage design, temperature control, and investment returns.
💬 Q1: Which is better for flower cold storage — pipe cooling or fan cooling?
A: Haocool recommends pipe (coil) cooling systems.
This method provides gentler cooling with smaller temperature fluctuations, reducing the risk of “cold injury” and excessive moisture loss.
Fan cooling systems, on the other hand, can blow cold air directly onto flowers and cause dehydration or damage to delicate petals.
Although pipe cooling systems provide slightly lower cooling capacity, they are much better suited for fragile blooms such as roses, lilies, and tulips.
💬 Q2: When should flower cold storage be used?
A: Flower cold rooms are used when flowers need to be stored or delayed before sale, especially when supply and demand are not synchronized.
For example:
- When flowers bloom earlier than expected, cold storage helps delay blooming and extend shelf life.
- When market demand is high, pre-cooled flowers can be stored to ensure continuous supply.
In short, cold rooms help maintain stable market availability and improve logistics efficiency for both growers and wholesalers.
💬 Q3: How long can flowers stay fresh in a cold room?
A:
- General flowers: 1–3°C storage can extend freshness by up to 30 days.
- Tropical flowers: 10–12°C is ideal.
Humidity should stay between 60%–85%.
With these conditions, flowers maintain vibrant colors, firm stems, and healthy appearance — ideal for export and high-end floral retail.
💬 Q4: What is the best storage temperature for flowers?
A:
- Ordinary flowers: around 5°C
- Tropical flowers: 10–12°C
- Roses: 2–5°C
If humidity and gas composition are also optimized, shelf life and freshness can be extended even further.
💬 Q5: How much does it cost to build a flower cold storage room?
A:
The price depends on size, temperature requirements, cooling method, and compressor type.
For example, a 1000 cubic meter flower cold room using Haocool equipment costs approximately $45,000–$55,000 USD, including installation and commissioning.
Our engineers provide on-site measurement, professional design, and a detailed quotation to ensure the most energy-efficient setup.
💬 Q6: What’s the ideal cold storage temperature for roses?
A:
For roses, keep the temperature between 2°C and 5°C, which extends freshness by around 3 weeks.
For best results, pre-cool the flowers before storage to quickly remove field heat and improve overall preservation quality.
💰 Investment Return Example
Let’s take a practical example:
- Project: Flower cold storage in Malaysia
- Storage capacity: 1,000 m³ (≈150 tons of flowers)
- Construction cost: ≈ $50,000 USD
- Power consumption: ≈ 2,800 kWh/month
- Average ROI period: 2.5–3 years
By investing in a flower cold storage system, the client reduced flower waste by over 35%, extended product life during transport, and secured better market pricing during high-demand seasons.
