  1. INTRODUCTION • Purpose • Understand electrical enclosure materials • Objectives • Learn about available electrical enclosure construction materials • Understand the factors used to select the proper enclosure material • Understand the tradeoffs between various materials & their performance impacts • Learning Time • 15 minutes 1

  2. PROTECT FROM THE ELEMENTS Industrial automation equipment can be used in almost any environment imaginable. Enclosures must protect these items from harmful elements to extend their life and prevent expensive operations downtime. 2

  3. INDUSTRIAL ENCLOSURE MATERIAL TYPES Different materials affect enclosure performance 3

  4. FACTORS IN DETERMINING ENCLOSURE MATERIALS Many factors to consider Environmental considerations Chemical resistance Heat absorption & dissipation Flexibility & ability to modify Impact resistance & material strength Weight considerations Aesthetics Purchase price 4

  5. IP20/IP30 TYPE 1 TYPE 12 IP54/55 TYPE 3R ENVIRONMENTAL CONSIDERATIONS TYPE 4 TYPE 4X MILD STEEL MILD STEEL MODULAR STAINLESS STEEL ALUMINUM NON-METALLIC IP66 IP69K Environmental ratings a primary factor in material selection 5

  6. CHEMICAL RESISTANCE Click here to access the Chemical Resistance chart http://www.hoffmanonline.com/stream_document.aspx?rRID=139153&pRID=139152 Hoffman has tested these materials extensively 6

  7. HEAT ABSORPTION & DISSIPATION GOOD (LOW) POOR (HIGH) HEAT ABSORPTION FROM ENVIRONMENT NON-METALLICS MILD STEEL STAINLESS STEEL ALUMINUM GOOD (HIGH) POOR (LOW) HEAT DISSIPATION FROM ENCLOSED EQUIPMENT ALUMINUM MILD STEEL STAINLESS STEEL NON-METALLICS Louvers, solar shields or active cooling equipment can be added 7

  8. SIZING FLEXIBILITY & ABILITY TO MODIFY EASY DIFFICULT SIZE ADJUSTMENTS MILD STEEL STAINLESS STEEL FIBERGLASS POLYCARBONATE ABS EASY DIFFICULT ABILITY TO MODIFY (HOLES & CUTOUTS) POLYCARBONATE ABS MILD STEEL FIBERGLASS STAINLESS STEEL Hoffman can provide modified features from the factory 8

  9. IMPACT RESISTANCE & MATERIAL STRENGTH HIGH LOW IMPACT RESISTANCE POLYESTER POLYCARBONATE ABS STAINLESS STEEL ALUMINUM FIBERGLASS MILD STEEL HIGH LOW MATERIAL STRENGTH STAINLESS STEEL ALUMINUM ABS POLYESTER POLYCARBONATE MILD STEEL FIBERGLASS Resistance to damage vs. strength to support components

  10. WEIGHT CONSIDERATIONS Must take into account weight of enclosed equipment RELATIVE WEIGHT FOR GIVEN SIZE ENCLOSURE (EMPTY) 10

  11. AESTHETICS Hoffman can provide almost any color imaginable 11

  12. PURCHASE PRICE LOWEST HIGHEST AVERAGE PURCHASE PRICE 316 STAINLESS ALUMINUM MILD STEEL POLYESTER POLYCARBONATE ABS 304 STAINLESS FIBERGLASS Price needs to align with customer requirements 12

  13. INDUSTRIAL ENCLOSURE MATERIAL TYPES Different materials affect enclosure performance 13

  14. SUMMARY THINGS AN APPLICATION SAVVY ENGINEER NEEDS TO KNOW Different industrial automation enclosure materials Different factors to help determine the enclosure material Which performance characteristics are important to the customer How different enclosure materials compare in different measures Selecting the right material is key to meeting customer needs 14
