Found within the cold chain are cold storage facilities such as cold rooms. These facilities store or process both refrigerated and frozen products. They can be at the actual process facility or part of the distribution chain.
Compliance with hygiene and food safety regulations, but also energy regulations, is critical. Whether for a new installation or renovation, other parameters that must be considered when purchasing a cold room include ease of selection, refrigerant choice, installation options, reliability, maintenance, and operating costs.
Revacco offers the widest portfolio of solutions for cold rooms to suit the diverse capacities, temperatures, and processes in small and larger sizes.
We offer contractor-friendly products & cold room solutions built with market leading expertise and enable you to comply easily with regulations and save on installation and maintenance of walk-in refrigerators. Make the right choice for optimum protection of perishables, efficient operation and long lifespan.
Our solutions for reliable walk-in cold rooms are specially developed to cover the extensive range of commercial refrigeration applications within; food service (restaurants, catering), specialty retail (butchers, bakeries etc.), process cooling (lab, medical, fruit ripening etc.), convenience stores, discount stores, and pharmacies.
Painted Galvanized Sheet
Painted galvanized steel sheets are hot dip galvanized by continuous process in accordance with EN 10143:2006 standards, with 100-275 gr/m2 zinc-coated. Galvanized coating improves corrosion resistance of the sheet. Due to its hardness, galvanized sheet is resistant to impacts and abrasion. On load bearing layers, galvanized sheet thickness should be minimum 0,50mm.
Stainless Steel
Stainless steel is especially preferred in the interior and exterior surfaces of the Cold Storage panel for hygiene because of its acidic environmental durability and corrosion resistance. It is produced in different qualities. Products should be selected by taking only the mechanical and chemical values into consideration. 316,304 and 430 grade stainless steel values in the following table are stated
Polyester
Polyester is the most simple and widely used topcoat paint among the paint types. It is widely used in interior and exterior surfaces. It is economical and it can be shaped easily. Since it has most appropriate cost, it can be supplied in all RAL codes.
Foodgrade/Foodsafe
Foodgrade or foodsafe paints are food compatible topcoat paints used in cold stores of food sector. They are especially resistant to oils, acids, alkalies and chemicals. They are suitable for vapor resistant and cold storage areas. They are free of solvents and toxic substances. They are resistant to radiation, humidity and moisture; easy to clean and have a good corrosion resistance.
PIR/PUR Insulation
Polyurethane (PUR)
Polyurethane is rigid polyurethane foam formed by the mixture of two main components named as polyol and isocyanurate under special production conditions, with catalyst materials and under high pressure. It has a closed cell structure. Thereby, it can provide excellent thermal insulation. Polyurethane density must be between the range of 40 (± 2) kg/m3 so that the thermal insulation coefficient is at the desired value and for the carrier characteristics of the panel. It has high dimensional stability. Water absorption is not available, it floats on water. No bacteria grows inside. Its usage performance is good since it has high compressive strength. Usage temperature should be 70-80°C maximum. Maximum resistance temperature is 100-110°C. Above this temperature it loses its characteristics.
Polyisocyanurate (PIR)
Polyisocyanurate (PIR) is formed as a result of the chemical reaction between the PMDI (polymeric methyl diphenyl isocyanate) or MDI and polyol. The amount of the mixture of MDI and polyol components differs polyisocyanurate from polyurethane. The amount of MDI used in PIR production and the amount of the flame retardant catalyst are higher. PIR is composed of isocyanurates chains which have higher chemical stability at high temperatures. PIR's flammability and smoke generation is very low compared to polyurethane. It creates excellent thermal insulation due to its closed cell structure. PIR should be used at maximum 80-90°C. Its maximum resistance temperature is 100-110°C. After this temperatures, it loses its function.
