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

Turn Key Cold Room Construction in Myanmar

coldroomplus — Tue, 04 Dec 2018 14:16:49 +0000

Turn Key Cold Room is for all of your cold storage requirements including cold room design, cold room manufacture and cold room installation. Kindly let us know your detailed requirements, such as the usage, temperature, or your special request on budget or energy saving. We can design a high – efficient and economic solution according to all of your requirements! Turn key cold room construction in Myanmar was just finished by OnlyKem team. There are some details about this cold room project, we hope that next cold room project is for you!

Turn Key Cold room specifications in Myanmar

Cold room usage: For frozen spinach storage

Cold room external dimension: 37200mm*23460mm*6450mm

Cold room layout: total six cold rooms and one corridor

Cold room insulation panels: 150mm thickness PU sandwich panels with good insulation effect, there is no cold losing, it will save power for customer.

Floor of cold room: XPS panel + cement. Customer need to drive forklift into cold room for loading and unloading goods, so we designed this floor system, it is strong enough to bear it.

Cold room temperature: -25 degrees celsius, keep spinach be frozen.

Ambient temperature in Myanmar: +45 degrees celsius.

Our solution as follows:

Condensation method: Evaporating cooled condenser.

Ambient temperature in Myanmar is very high in summer, it can reach 45 degrees celsius even more higher temperature, air cooled condenser is not workable, because air cooled condenser uses hot air as medium for the heat exchange, it is not efficient with so high temperature.

Finally our engineer chose evaporating cooled condenser, in this solution, it uses water and air as cooling medium exchanges the heat with high-heat gaseous refrigerant medium and hence the refrigerant medium becomes liquid. Inside, there is water distribution system, heat exchange coil, Outside, there is water circulating pump, electronic water curing device and propeller fans on the top of heat exchange coil. Evaporating cooled condenser will be more and more popular in the tropical area.

Advantages of evaporating condenser:

Excellent heat exchange performance with water

Convenient and realizable on-line maintenance

Small floor space and low investment

Convenient transportation and installation

Low operating cost and energy saving

Low fault rate

Slope collecting basin with convenient clean out

2. Compressor unit type: Origianl new German Bitzer brand, screw compressor, parallel system.

Electricity is very expensive in Myanmar, so customer wants the energy saving solution; Besides, sometimes they don’t put full frozen spinach in the Turn Key cold room, so all compressors don’t need to work all the times. Considering these points, our engineer suggested that parallel system for customers.

Advantages of parallel system:

Integrated PLC control system.
Automatic control system: it can adjust the number of working compressors automatically according to the cooling capacity required in cold room. It means that not all compressors keep working always, so it is energy saving than the single unit.
Remote monitoring system: we can help customers debug machine in China, so it can realize online-service in the future, it is very convenient and in-time after – sales service.
Backup function: If one compressor has problems, other compressors can replace it for working. It can keep cold room temperature continuously. Spinach won’t be affected because of the sudden problems.
Long lifespan: Because it can adjust the compressor working time automatically according to the cooling capacity required, so the compressors have time of rest, their lifespan is about 30% longer than the single unit.

OnlyKem installation team for Myanmar Turn Key cold room project!

Our experienced refrigeration engineers worked for designing and installation guiding for customer. There ware three stages for the whole installation.

Firstly our engineer inspected customer’s site, in order to check if it is suitable or advantageous for good running and installing of machines, our engineers gave some useful suggestions in this stage, such as we suggested customer utilizing high quality water, because evaporating cooled condenser need water as heat exchange medium, low quality water will have water rust or impurity, after long time, it will reduce heat exchange rate.
Secondly, our engineer designed professional drawing according to actual site, it is helpful for the fast installation. With the drawings, installation team understood some details very easily and clearly.
Thirdly, our engineer helped debugging machine until they worked well!

From ordering to installation implementation of Turn Key cold room, our Myanmar customer felt OnlyKem team’s enthusiasm and profession. We had provided many types of effective and states of the art cold rooms to over 45 countries. Our customers are from Swiss, Sweden, Australia, USA, Canada, New Zealand, Japan, Pakistan, Spain, India, Malaysia, Singapore, Myanmar, Philippines, South Africa, Argentina, Indonesia, Kenya, Algeria, Ghana, Guyana, Mongolia, Chile, Peru, Dubai, Poland, Mexico, Brazil, Lebanon, Thailand, Kazakhstan, Turkmenistan, Bangladesh, Colombia, Bahrain, etc. If you have requirements on cold room in future, OnlyKem is a good choice for you!
