1. ‌Clarify Purpose: What Will the Cold Storage Store?‌

1.1 Industrial Cold Storage‌: Ideal for bulk storage of raw materials or finished products.such as meat and seafood in food factories, or vaccines and pharmaceuticals in drug manufacturers.
1.2 Commercial Cold Storage‌: Commonly used in supermarkets and restaurants for short-term turnover goods like fruits, vegetables, and dairy products.
1.3 Key Point‌: First determine the product type, as different items have varying requirements for temperature and humidity.

2. ‌Choose the Right Temperature: Products dictate “Coldness”‌

2.1 Fruit & Vegetable Preservation‌: 0~15°C (maintain freshness, delay spoilage).
2.2 Meat Freezing‌: -18°C or lower (long-term preservation, prevent, deterioration).
2.3 Special Needs‌: Ice cream requires -25°C; some pharmaceuticals may need -60°C ultra-low temperature storage.
2.4 Recommendation‌: Incorrect temperature selection can spoil products, so ensure it matches storage needs.

3. ‌Size & Insulation: Tailor Fit to Save Money‌

3.1 Cold Storage Size‌: Estimate based on cargo volume. For example, storing 1000 boxes of fruit may require 50㎡, while large equipment needs more space.
3.2 Cold Storage Panel Thickness‌: The lower the temperature, the thicker the insulation layer.

Use 10cm thick polyurethane panels for 0°C storage, 15cm for -18°C, and 20cm for ultra-low temperature storage.

4. ‌Refrigeration Equipment: Choose Suitable, Not Expensive‌

4.1 Refrigeration Unit : Small cold storage (<50㎡) use air-cooled units (cheap, easy to install); Large cold storage (>100㎡) use parallel screw compressors (efficient, energy-saving).
4.2 Air Cooler: Select materials based on temperature. Use copper tubes + aluminum fins for fruit & vegetable storage (rust-resistant); stainless steel for freezer storage ( low-temperature resistant). Avoid iron materials, as they will rust and fail.
4.3 Defrosting Methods‌: Water defrosting suits fruit & vegetable chiller storage (low cost); electric heating suits freezer storage (high automation).
4.4 Tip‌: Incorrect equipment selection can skyrocket energy consumption—consult an onlykem engineer for matching!

5. ‌Controller: Smart but Simple‌

5.1 Basic Type‌: Manual switch + thermometer (suitable for small cold storage, lowest cost).
5.2 Advanced Type‌: Automatic temperature control (suitable for high-traffic cold storage, reduces, manual inspections).
5.3 Note‌: Avoid complex systems unless absolutely necessary.

6. ‌Cold Room Door: Ensure Easy Access for Large Items‌

6.1 Small Goods‌: Manual sliding door / Hinge door (cheap).
6.2 Large Goods/Forklift Operations‌: Electric sliding lift door (good sealing, prevents, cold air leakage).
6.3 Anti-collision Design‌: Add sealing strips to reduce heat loss when opening.
6.4 Reminder‌: Wrong door choice can cause cold air leaks and double electricity bills!

Summary: Three-step Cost-saving Method‌

Define Purpose & Temperature First‌: Avoid “over-cooling”.
Accurately Calculate Size & Equipment‌: Don’t waste space or energy.
Choose Reliable Suppliers‌: Fast after-sales response reduces downtime.

💡 ‌Cold Storage isn’t “the more expensive, the better” – it’s “the more suitable, the more economical”! Need a specific plan? Leave your requirements – I’ll help you calculate!‌ #Cold Storage Construction #Refrigeration Engineering #Cost Saving Guide

Chiller Cold Room for Nuts is a perfect cold storage room project to store nuts in Middle-East Area. It won a good reputation from our customer. Thus, our customer gave us a good feedback.

1. Chiller cold room for nuts in Saudi Arabia has a customized design.

Panels System of Chiller Cold Room for Nuts in Saudi Arabia
According to our experience, the storage temperature for nuts will be -5~+5℃. Normally the panel we used is 100mm PU panel if the temperature is -5~+5℃. Because of hot weather and dry environment in Saudi Arabia, we confirmed finally the thickness is 120mm after we talked about with technician department. So that we can promise the temperature well and store the nuts well. And the surface material, what we used for this project is 0.5mm color steel. It can protect the chiller cold room for nuts avoiding the damage from weather. Thus, the cold room can be used more times.

Refrigeration Unit System of Chiller Cold Room for Nuts in Saudi Arabia
As we all know, the nut has a high requirement on the store temperature. We must control the temperature strictly. So we need to design a refrigeration system which can brings large cooling capacity for the chiller cold room for nuts in Saudi Arabia.
According to our experience, the compressor we used for this project is Bitzer compressor. Bitzer, a famous brand from Germany. This compressor has a large cooling capacity and it can suit bad weather environment. After our deep discussion, finally we designed Bitzer compressor for this chiller cold room for nuts in Saudi Arabia. And,according to our market survey, Bitzer compressor is very popular in Saudi Arabia and its around area.

What’s more, the condenser has a double area based on normal condenser. Because the weather in Saudi Arabia is very hot. In order to let the heat spread out more efficiently, our engineer suggests that add extra area for condenser. Enough area can help the wind bring the heat out more efficiently though the weather is very hot.
So, please do not worry about the cooling efficiency, our engineer who has more than 15 years experience can make a perfect proposal for you.

2.Chiller cold room for nuts in Saudi Arabia has a low cost of installation

There are many customers worry about this problem, how can they install the cold room? Is the installation very difficult?
As a professional cold room supplier, we have put these problems into our consideration. Our aim is provide the most convenient proposal for our customer. Try our best to let our customer save the cost of installation.
Panels Connection of Chiller Cold Room for Nuts in Saudi Arabia
The panel connection is Cam – Lock. When we make the panels, we put cam – locks into the panel. According to the workers experience, every cam – locks will be on their position exactly. After we put the panels together, we use the handle to lock the cam – lock. Very easy to do this. Then the panels connection is finished.
Installation Drawing of Chiller Cold Room for Nuts in Saudi Arabia
When we arrange the production, we always make a CAD drawing.In order to let our customer beconvenient when they install the chiller cold room, we also send this drawing to customer. Every panels has their position so that we can install the chiller cold room more clearly.

3. Chiller cold room for nuts in Saudi Arabia has all certifications.

As we all know, we must make a certification for the goods if we want to export our goods to Saudi Arabia. According to SASO, we need to make a COC certification on the goods. No certification, no export.
It means our goods must have a high quality. Fortunately, with our high attention on goods and production, our goods can meet the standard of Saudi Arabia Government. So surely we can get the certification from SASO.
Not only SASO, but some customers also need CCPIT certification. So it means there is a higher standard on our goods. And we also need to pay more money on it. But do not worry. We can do it! What’s more, we always do it for our customer freely.
With our many years experience, we know what documents the Custom need and we also can get those documents with a low price. So please do not worry about the documents of Custom. OnlyKem will give a perfect solution.

The chiller cold room for nuts in Saudi Arabia has been finished for a couple weeks. From the feedback of customer, everything goes well. And, it is our pleasure to build the chiller cold room for nuts for customer in Saudi Arabia.
