Yes, we can provide estimated prices, but it's important to note that each project is custom-designed to meet your specific needs. Factors such as door size, capacity requirements, floor area, and the height of the cold room all play a crucial role. Given the many variables involved, we at Celtic Cooling prefer to work closely with you, addressing each step of the project to develop a tailored, cost-efficient solution that effectively resolves your challenges. While we can offer global estimates, please remember that these are general and subject to refinement based on the specifics of your project.

Unfortunately, in 90% of cases, payments for materials need to be made in euros or dollars. However, local materials, such as refrigerants and installation services, can be paid for in the local currency of our regional offices.

Implementing solar panels is a great way to reduce your energy bill. However, it is important to connect the equipment to the grid to ensure stable temperatures and prevent any negative impact on products or processes.

When building a freezer, it is crucial to consider the risk of the concrete floor freezing and cracking due to the below-zero temperatures. To prevent this, you have two main options: Install underfloor heating, which can be either electrical or a glycol-based system that uses recovered heat from the refrigeration unit. Construct a higher deck on ventilation beams to prevent frost formation. However, this solution is only feasible for small freezers.

At higher altitudes, the air is less dense, reducing the condenser's ability to reject heat effectively. This necessitates larger or more efficient condensers to maintain the same cooling capacity. Here's a simplified table showing the approximate capacity loss at different altitudes: Altitude (meters) Approx. Capacity Loss (%) Remaining Capacity (%) Sea level (0 m) 0% 100% 1,000 m 10% 90% 2,000 m 20% 80% 3,000 m 30% 70%

Selecting a condenser with a lower delta T (temperature difference) typically results in significant energy savings. Delta T in this context refers to the temperature difference between the condensing temperature of the refrigerant and the ambient air temperature. A lower delta T means the condenser is more efficient at rejecting heat, which translates to lower energy consumption by the compressor. Lower Condensing Temperature: When you select a condenser with a delta T of 10°C instead of 15°C, the condensing temperature of the refrigerant will be closer to the ambient temperature. For example, if the ambient temperature is 30°C: - With a delta T of 15°C, the condensing temperature will be 45°C. - With a delta T of 10°C, the condensing temperature will be 40°C. Compressor Efficiency: Compressors consume less energy when they work at lower condensing temperatures. The power required by a compressor is directly related to the difference between the suction and discharge pressures. Lower condensing temperatures reduce the discharge pressure, thereby reducing the compressor's work and energy consumption. Energy Savings Calculation: The exact amount of energy saved depends on the specific system characteristics, including the type of refrigerant, the efficiency of the compressor, and the load conditions. Generally, a rule of thumb is that for every 1°C reduction in condensing temperature, there is a 2-3% reduction in compressor energy consumption. Calculation Example: - Initial delta T: 15°C (Condensing Temperature: 45°C) - New delta T: 10°C (Condensing Temperature: 40°C) - Reduction in condensing temperature: 5°C Estimated energy savings: - Energy savings percentage per °C reduction: 2.5% (average of 2-3%) - Total reduction: 5°C × 2.5% = 12.5% Summary: By selecting a condenser with a delta T of 10°C instead of 15°C, you can achieve significant energy savings, potentially reducing compressor energy consumption by around 12.5%. This improvement in efficiency not only lowers operational costs but also enhances the overall performance and lifespan of the refrigeration system.

Comparison: Many cold room suppliers using local or imported Expanded Polystyrene (EPS) sandwich panels to construct their structures. Celtic is using sandwich panels with a high-density polyurethane (PUR) insulated core, we would like to highlight the differences and benefits of our choice. Thermal insulation properties: Celtic offers high-density PUR panels. The heat transmission coefficient for 80 mm thick PUR insulated panels is 0.276 W/m²K, where EPS with similar thickness would be roughly 0.45 W/m²K. To get the same thermal insulating qualities as our panels, a minimum thickness of 150 mm EPS is needed, which will increase the shipment volume substantially. Our selected panels making them highly efficient preventing cold losses from inside and impact of external heat transmission. Energy efficiency: Because of the high thermal insulation of the InspiraFarms sandwich panels, less energy will be used on a daily-monthly basis than locally manufactures polystyrene panels. This will have an impact on OPEX costs over time. As an example, for your facility, with a total surface area of 1,375 m² of external facing sandwich panels, and a temperature difference of 30°C between inside and outside of the cold rooms, the difference between 80 mm PUR and EPS will be: 1,375 * 30 * (0.45-0.276) * 24 hr = 172.3 kWh thermal per day. Assuming that the Coefficient of Performance of the whole cooling system is approximately 2, there would have an additional electric energy use per day of over 86 kWh Health and Safety and Certifications: There are increasing concerns about the use of polystyrene panels by International certification bodies, environmental groups and retailers. This is both from a health and safety (our PUR insulated sandwich panels have a Fire Resistance class) and environmental perspective. The high density PUR panels are EU certified and have no such concerns.

Ceiling panels have a certain span. Proper support ensures they don't sag or collapse under their own weight or additional loads like machinery, light fixtures, or evaporators. 60mm Panel Thickness: Typical Span: 2.5 to 3.0 meters 80mm Panel Thickness: Typical Span: 3.0 to 3.5 meters 100mm Panel Thickness: Typical Span: 3.5 to 4.0 meters 120mm Panel Thickness: Typical Span: 4.0 to 4.5 meters 140mm Panel Thickness: Typical Span: 4.5 to 5.0 meters 160mm Panel Thickness: Typical Span: 5.0 to 5.5 meters Live Loads: The presence of live loads such as personnel walking on the ceiling for maintenance, equipment, or stored goods can affect the span. Deflection Criteria: The allowable deflection (typically L/200 to L/300 of the span length) is a critical factor in determining the span.
