INCORPORATING COLD CHAIN
• The size of the facility / rooms you need and the dependence on space needs and traffic .
• The type of product or process that will be stored or completed
• Volume of product entering and leaving
• Processing versus storage needs
• Temperature at which product is expected to enter or leave the process line
• The required storage temperatures ( pull down , chill , freeze )
• Door sizes that will affect heat transfer
• Geographic location of the installation ( not a universal solution )
Answering some of these questions will lead you to be able to consider some product specific elements , some of which have become more important today than ever , such as :
• Environmental impact
• Product stability ( R-value range )
• Moisture resistance
• Service temperature range of the product ( ie -40 to + 120 )
• Structural stability
• Performance tests in various scenarios
• Grade and density ( eg 15kg / m 3 to 80kg / m 3 )
• Complete product lifecycle and recyclability
• Local content and industry support
• Price
The conditions required around any facility will determine the product configurations .
Precool Manufacturing
An installation of insulated panels showing their use for walls , ceilings and doors . All manufactured locally .
So , a company that for example extracts citrus oil from orange peels would require polyurethane insulated panels because this material type doesn ' t disintegrate when exposed to the particular acid found in citrus oil . Also , as a closed cell material this means that the structure of the core doesn ' t allow substances to easily penetrate it . The same conditions apply to the skins . Here if corrosion was likely such as the circumstances with working in an abattoir , the faces would need to be
