Best Flower Chiller Temperature in UAE: Complete Guide for Different Flowers

For the majority of cut flowers, such as roses, carnations, lilies, tulips, gerberas, and chrysanthemums, set your chiller between 0°C and 4°C with humidity close to 90%. Bird of paradise, anthurium, and many orchids that bloom in warm climates like a temperature between 5°C and 15°C. Chill them like flowers and they will be destroyed within a day or two.
Every line below is fresh because I completely rewrote this tutorial. It is intended for wholesalers, hotel staff, and florists in the United Arab Emirates who desire longer-lasting bouquets and fewer bin-bound stems.

What Is the Best Flower Chiller Temperature in the UAE?

Cold storage can be compared to a pause button. A sliced stem matures slowly, loses less moisture, and slowly burns through its stored sugar when it gets close to freezing. Because of this, the majority of temperate flowers belong in the 0–4°C range.

The other side of the equation is humidity. Air that is excessively dry sucks water out of petals and leaf edges, so even a perfectly cold unit might leave flowers limp. A goal of 85-95% maintains stems solid.

Tropical flowers originated in warmth, and their cells are harmed by cold. Below their comfort zone you will witness blackened edges, glassy-looking petals or buds that stay shut. Depending on the type, keep these between 7 and 15°C.

The honest answer, then, is that the best temperature depends on what is inside the chiller. The sections below give you the number for each flower.

Why Flower Chiller Temperature Matters in the UAE Climate

If one has experienced leaving a van out during the month of July, one knows how quickly temperatures rise. Since most outdoor temperatures have reached levels above 45 degrees, a delivery without refrigeration would consume several days of the flower’s life.

There is the actual journey. As most flowers that you deal with are transported to your place via air from the Netherlands, Kenya, Ecuador, Colombia, or India, the stems are already tired upon arrival. Hence, the quality of care that the flowers receive during the first hours after arrival determines how long the flower will last.

Three things make a good chiller valuable for the flower shop owner:

•           It slows down the internal stem clock, hence the gradual bloom rather than the sudden one.

•           It neutralizes the effect of ethylene, a chemical which makes flowers age faster.

•           It fights bacteria, ensuring clean water and ability to drink.

Best Storage Temperature for Different Types of Flowers

Here is a handy cheat sheet for the wall beside your chiller.

Flower	Temperature	Humidity	Watch out for
Roses	0-2°C	85-95%	Ethylene from fruit
Carnations	0-2°C	85-95%	Ethylene sensitivity
Chrysanthemums	0-4°C	85-95%	Submerged leaves
Lilies	1-3°C	85-90%	Pollen staining
Gerbera	2-4°C	85-90%	Weak necks
Tulips	0-2°C	85-90%	Stems bending
Orchids	5-10°C	85-90%	Cold burn, drafts
Anthuriums	12-15°C	85-90%	Chilling injury
Birds of Paradise	7-10°C	85-90%	Mould, bruising

Treat these as dependable starting points. Growers sometimes refine them by variety, so check supplier notes when you can.

Best Temperature for Roses

The majority of income for florists in the UAE comes from roses, making them the first flower to pay attention to. Keep them between 0-2°C.

Once they are received, cut a couple of centimeters from each stem, remove all the foliage below water level, and place them in clean buckets with flower food. Make sure to keep them separate from fruit crates; a single ripening mango crate will cause roses to bloom prematurely and lose petals.

Best Temperature for Carnations

Carnations are the marathon runners of the cooler; at 0-2°C they can last for a very long time. The one downside that they have is ethylene; exposure to even low concentrations can make petals curl and discolor.

Best Temperature for Chrysanthemums

Chrysanthemums are forgiving. Anywhere from 0-4°C keeps them looking good. The main chore is stripping leaves below the waterline. Decaying foliage turns bucket water cloudy and shortens the life of every stem sharing it.

Best Temperature for Lilies

Lilies like 1-3°C. Once the flowers open, pinch off the pollen-covered anthers. This prevents the stubborn orange stains that can mark petals, shop counters and customers’ clothes, and it helps the bloom last a little longer.

Best Temperature for Gerbera

The stem of the gerbera is very delicate and soft. It has a tendency to collapse just below the flower head. Therefore, keep the flower at 2-4°C temperature and place it vertically with just a few cm of water. Large buckets encourage bacterial multiplication in the flower stem.

Optimum Temperature for Tulips

Even when cut, tulip flowers show growth toward light sources. That’s the reason why the flower bends and twists while in a bouquet display. Keep them at 0-2°C temperature.

Optimum Temperature for Orchids

If we talk about cut orchids like Dendrobium and Cymbidium, the optimum temperature should be 5-10°C. Otherwise, the petals may get brown and buds fall off. Place the flower away from the airflow of the refrigerator fan.

Ideal Temperature for Anthuriums

Anthuriums are tropical flowers and are highly sensitive to cold temperatures. Store them at 12-15°C. Anything below around 10°C and the glossy heart shaped spathes will start to discolour, and this discoloration cannot be reversed.

Ideal Temperature for Birds of Paradise

The showy stem flowers thrive in temperatures of 7-10°C. Keep the moisture content low in the bracts to avoid any mould formation, and handle with care as even a slight touch leaves a mark which does not disappear easily.

Ideal Temperature and Humidity for Tropical Flowers

Tropical flowers are best stored in moderate conditions where the humidity is consistently at 85-90%. Should your inventory include both roses and tropical flowers such as anthuriums or birds of paradise, there are two solutions – a dual chambered chiller or separate chillers. Keeping a single chiller at a mid point temperature is always a compromise since it is too hot for roses and too cold for tropicals.

How to Choose the Right Flower Chiller for Your UAE Business

Buying a chiller is a long-term decision, so a few questions are worth asking first.

• How big does it need to be? Plan for your busiest weeks. Valentine’s Day, Mother’s Day and Ramadan can multiply your stock several times over.
• Which format fits your space? Single, double and triple-door display units suit shops that sell directly to walk-in customers. Walk-in rooms suit hotels, wholesalers and event florists.
• Can it control humidity as well as temperature? A unit that only cools is only half the job.
• Is it built for local conditions? Look for strong condensers and solid insulation, since the unit has to cope with serious summer heat.
• Do you need something bespoke? Many hotels and larger operators need non-standard sizes, shelving or temperature zones.

FlowerChiller.ae supplies single door, double door, triple door, walk-in and customized floral chillers made with UAE conditions in mind.

Common Flower Chiller Temperature Mistakes

The reasons for such losses usually can be narrowed to several mistakes that are easy to correct.

1.         Every flower – its own place. Tropical plants and plants from temperate climate zone require distinct conditions.

2.         Crowded shelves. Stagnation of air causes warm zones, where the flowers will wilt faster.

3.         Humidity ignorance. The dry cold air dehydrates the petals anyway.

4.         Keeping flowers near fruit or vegetables. The ethylene, emitted by them, will spoil the whole delivery.

5.         Keeping doors open. Every time the doors open, hot and humid air penetrates into the fridge, making compressor work more intensively.

6.         Hygiene neglect. Dirty buckets and shelves cause development of bacteria, slimy stems and unpleasant smell.

Flower Chiller Temperature Guide for Florists, Hotels and Wholesalers

Florists: A walk-in refrigerated cooler at 2-4°C is appropriate for roses and assorted bouquets. The unit can double as a shop window as well. Create a warm section to ensure that tropical flowers do not get chilled accidentally.

Hotels & venues: Big wedding ceremonies and banquets translate into large orders, which have to be delivered fresh. Walk-in coolers at 2-4°C are best for the job. If you use tropical flowers, then you need a separate warm corner in addition to the cooler.

Wholesalers: At high volumes, airflow, temperature control, and zoning become very important considerations. A walk-in or specially designed chiller taking into account how your company handles orders can pay off better than any other option.

Conclusion

For the UAE, the optimum temperature setting in the cooler will depend upon the flowers being stored. The optimum range should be set between 0-4°C for storing roses, carnations, chrysanthemums, lilies, gerbera and tulips, while for orchids, anthuriums and birds of paradise, it is between 5-15°C, along with maintaining high levels of humidity throughout.
