Cold rooms are temperature-controlled environments essential in the food industry, as well as in the pharmaceutical industry.
One or more rooms connected together allow to obtain rooms for the preservation, refrigeration or pre-cooling of products, in which a stable and pre-set temperature must be maintained: this degree of temperature depends on the function to which the room is defined, which can vary from + 18 ° C for ripening fruits such as bananas and avocados, to -28 °C for freezing fish or vegetables, or in the case of the pharmaceutical industry, to keep samples, tissues and vaccines at ideal temperatures for their study and application as would be the vaccine against COVID-19.
A cold store requires a detailed specification according to the materials to be used, to obtain the necessary insulation, therefore reducing processing and maintenance costs. The analysis consists of identifying the performance required to maintain regularity in internal conditions, particularly temperature.
Clean rooms are recurrent in the food and pharmaceutical industries, but we can also find in the mechanical, electronic, automotive, and aerospace industries, which increasingly require some sterile processing areas to ensure the safety and hygiene of the finished product. Clean rooms are clean, controlled, and sterilized areas with controlled atmosphere. It means that the air inside them contains a minimum amount of suspended dust particles. Their construction, appropriate use and maintenance are constantly regulated by national and international standards.
Positive temperature cold rooms
They provide a suitable environment for storing "fresh" food in industrial quantities, guaranteeing constant temperatures and low humidity values, through insulating coatings with low thermal transmittance. In the case of pharmaceuticals, they are used for the preservation of some sample tissues and medicines.
Negative temperature cold rooms
Characterized by a temperature range between 0°C and -28°C, negative temperature cold rooms are used for the pre-cooling of fruits and vegetables, refrigeration, freezing and ultra-freezing. On the other hand, in the pharmaceutical industry they are used for the preservation of vaccines that require ultra-freezing environments as is the case of the recent COVID-19 vaccine. They provide a suitable environment for food storage and freezing with strict temperature control, ensuring that the humidity and internal atmosphere by means of insulating shells has very low transmittance and thermal dispersion.
Suitable materials for cold rooms
For temperature-controlled spaces such as cold rooms or clean rooms, for example, there are different types of insulating panels that help ensure the necessary temperatures for the storage of food and medicines. Insulating panels for temperature-controlled environments can be made of various materials, coated in antibacterial steel, pre-painted sheet metal or stainless steel, depending on the performance of resistance and reaction to fire and/or durability.
For temperature-controlled environments, polyurethane or polyisocyanurate insulated panels such as isoparete frigo and isobox frigo, designed by IsoCindu, are mainly used, specifically for the food and medical industry, combining insulating properties, either with hidden or exposed fixing and ideal tongue and groove to avoid thermal bridges and improve insulation.
To maximize thermal performance and guarantee up to 20% less heat loss, IsoCindu has new generation formulations with LEAF technology, which has an excellent reaction to fire without halogenated components, harmful to the environment.
IsoCindu insulating panels represent one of the most useful solutions in the field of cold chain processing and maintenance.
