Nowadays, it is critical to preserve products in appropriate conditions in many areas from the food industry to the pharmaceutical industry, from the chemical industry to the logistics sector. At this point, cold rooms have become indispensable elements for protecting and maintaining the quality of products. One of the most fundamental factors determining the performance of cold room systems is the right panel selection. In this blog post, we will examine in detail the critical importance of cold room panel selection in industrial facilities and the advantages that the right choice will provide to businesses.

Basic Function and Components of Cold Room Panels

Cold room panels are basically sandwich-structured components that provide insulation between the external environment and the controlled environment inside the cold room. These panels usually consist of the following layers:

1. External and Internal Coating: Surfaces usually consisting of galvanized, painted or stainless steel sheets
2. Insulation Core: Insulation materials such as PUR (Polyurethane), PIR (Polyisocyanurate), EPS (Expanded Polystyrene) or rock wool
3. Joining Systems: Boltless, locking or concealed mounting systems

The cold room panels produced by Anadolu Panel are designed to meet different industrial needs with the optimum combination of these components.

Comparison of Different Types of Cold Room Panels

PUR/PIR Insulated Cold Room Panels

PUR/PIR filled panels are the most widely used panel type in cold room applications. These panels offered by Anadolu Panel have the following features:

Advantages:

• Superior Thermal Insulation: Low thermal conductivity coefficient (λ=0.022-0.025 W/mK)

• Light weight: Reduces load on the load-bearing system

Suitable Temperature Ranges:

• Cold Storage (0°C to +4°C): Short-term storage of fresh food
• Frozen Storage (-18°C to -25°C): Long-term storage of frozen foods
• Blast Freezing (-35°C to -40°C): Applications where products need to be frozen quickly

Ideal Usage Areas:

• Food storage facilities
• Meat and dairy processing facilities
• Frozen food production facilities
• Flower and plant storage areas

EPS Insulated Cold Room Panels

EPS filled panels that can be preferred in cost-oriented projects:

Advantages:

• Economic Solution: Low initial investment cost
• Light weight: Easy assembly and transportation
• Good Thermal Insulation: Acceptable thermal conductivity value (λ=0.035-0.040 W/mK)

Suitable Temperature Ranges:

• Cold Storage (0°C to +15°C): Applications with low cooling requirements

Ideal Usage Areas:

• Vegetable and fruit storage areas
• Short-term storage needs
• Small-scale enterprises
• Back warehouse areas of department stores

Cold Room Panel Selection by Industries

Food Industry

In the food industry, where food safety standards are critical, the following factors should be considered in panel selection:

• Hygiene Requirements: Panels with antibacterial coating
• Temperature Fluctuation Tolerance: High insulation value panels that minimize heat loss due to door opening and closing

Impact of Panels on Energy Efficiency

Energy costs account for approximately 60-70% of the operating costs of cold room systems. Therefore, panel selection directly affects the operating economy:

Thermal Transmittance Coefficient (U-value) and Energy Consumption

U-values of panels of different thicknesses and their effect on annual energy consumption:

*According to the reference value, under similar cold room conditions

Amortization Period Calculation

Impact of increasing panel insulation thickness on initial investment cost and payback period achieved through energy savings:

• Preferring 120 mm PUR/PIR panel instead of 80 mm: Approximately 15-20% cost increase in the initial investment, but payback in 2-3 years through energy savings.
• Preferring 150 mm PUR/PIR panel instead of 100 mm: Approximately 12-15% cost increase in initial investment, payback in 3-4 years

Anadolu Panel’s energy efficiency-oriented solutions provide significant savings to businesses in the long term.
