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

Cold Room for Sale is the hot sale cold storage room of Onlykem brand which is widely used to store many kinds of products such as fruit, vegetable, beer, frozen food, etc. The function of cold room for sale is to maintain a suitable and stable temperature. Let’s take the newly completed beer cold room project as an example. The temperature requirements for brewing and storing beer are very strict, which is an important factor affecting beer quality.

Functions of Cold Room for Sale

The controlled temperature in the beer production process is very important. Depending on the type of beer you brew and how you serve it, you may want to control temperatures in the 0℃ range (for storage) or you may need something closer to 10℃ (for fermentation). For storing kegs or running tap lines to your tasting room, you probably want to maintain temperatures between about 0℃ and 5℃. If you are doing all of these things, you may even need to switch between higher and lower temperatures at different stages of the process.

The trick is that you need to be able to control the temperature precisely so that you can ensure that every batch you bottle and pint you pull will be perfect. Reliable controlled cold room is important.

PU Panel for Beer Cold Room

We upgraded raw materials for PU sandwich panels. The original FC11 took the place of HCFC-141B, HCFC-141B is more environmental friendly than FC11. In a word, current PU panels are more environmental friendly than previous panels, they are not only contributed for world environment, but also healthful for beer storage inside of cold room.

Panel: Polyurethane panel tough groove dry joint with cam lock

Thickness: 100 mm

Color: White with OnlyKem film

Width: 960 mm, 1000 mm

Length: According to customer requirement, the max length is 1190 mm

Density: 44(kg/m3)

Sliding Door for Beer Cold Room

The size can be customized;

Sliding door built-in metal frame;

The edge of the door frame is provided with a low temperature resistant sealing strip;

Stainless steel hinge and door lock;

Door frame with built-in cam-lock;

Use stainless steel rails, stainless steel screw bolt.

Refrigeration Systems

Condensing unit includes New original German brand Bitzer compressor, crankcase heater, vibration absorber, air cooled condenser with large heat exchange area, axial fan, liquid receiver tank, sight glass, dry filter, solenoid valve, dual pressure switch, dual pressure gauges, oil separator, suction accumulator, etc.

Our condensing units have more complete accessories, some suppliers do not include oil separator or vibration absorber, it is not good for whole system running in long terms. In addition, we use Danfoss brand for some important components, such as Danfoss sight glass, solenoid valve, pressure gauges, it could extend long lifespan, some suppliers use other brand components for them, there is big quality difference between them.

New generation of condensing unit with Ozone friendly refrigerants, R404a;

Designed for ambient temperature of up to 52℃;

High pressure safety cut off with manual reset;

Axial fan motor, high air flow with low noise;

Air cooled condensing unit, high performance and convenient;

Over 363 PSI dry nitrogen gas pressure test after completion of the piping circuit, no leakage;

Axial fan motor, high air flow with low.

Tips of Cold Room for Sale

In order to make the air flow in the cold room, the stacking code should not be too crowded, the stack and wall stack should be kept about 1 meter. There should be about 80 cm between the top of the stack and the ceiling or ceiling duct, the distance between the stack and the evaporator should be kept at least 2 meters. The berries close to the evaporator or roof panel is liable to freezer damage.

In the same cold room, it is best to store only one kind of beer and try to avoid mixed storage of different properties.
