Product Name: Honeycomb Airflow Straightener (PC3.5, PC6.0) Model NO.: PC3.5-8.0 Certification: RoHS Usage: for Refrigerate Material: PC Cooling Method: Indirect Cooling Cell Diamesion: 3.0-8.0mm Thickness: 2-80mm Tolerance: +/-0.5mm Common Dimension: 900*1250mm Max Dimension: 1250*3600mm Trademark: Polycore Transport Package: Carton Specification: max1250*3600*80mm Origin: China HS Code: 3926909090 Product Description The honeycomb airflow straightener characteristic plays a very important role on the performance of vertical and stand refrigerated display case. The transient temperature of the display case shelves was measured for studying the temperature variation and distribution in the vertical display case by changing the number and the velocity of air flow. The result shows that it is necessary to keep three airflow in a vertical open low temperature display case and the performance of the display case can be improved by selecting reasonable airflow velocities.PC honeycomb has excellent compressive strength act as airflow in refrigerated display cases. Polycore provide airflow has excellent properties:1. Core uniformality, inside smoothness, cleanness, surface level off.2. PC raw material is safe for using as air filter in showcase.3. Lower shrink rate when temperature drop to -30 degree. This is very important for durable life of airflow and provide installation safety for showcase manufacturer and supermarket operator.Avalibility:Available corecell diameter: 3.0mm---9.0mmCommon dimension: 1270x630mmBiggest dimenstion: 1250x3600mmThickness: 2mm---340mm Tolerance: +/-0.3mmCommon corecell diameter we supplying is 3.5mm, 6.0mm, 7.0mm and 8.0mm, if you need other corecell we can make it too (order quantity is reach to 40'c once time).Common length is within 1265mm, width and thickness is made according to customer requirement.
