Hoffman Stainless Steel HMI Enclosures

HMI enclosures are designed specifically for the wide range of Human Machine Interface applications found in industrial settings. It is important to have customization options like removable front plates that allow for easy installation of HMI components, optional door panels that can be mounted anywhere and cutout options where needed. Some enclosures are designed to enclose, protect and suspend lightweight HMI devices. HMI enclosures should always be rated to protect sensitive systems from the sometimes harsh environments found in industrial settings. This would include protection against moisture, chemicals and dirt, as well as, temperature variations.
Hoffman stainless steel HMI enclosures are ideal for use in the pharmaceutical and food industries. The Type 304 stainless steel enclosures are corrosion resistant for easy cleaning and wash down. A pre-drilled hole allows for mounting to various support arm systems from a top or bottom position. Hoffman stainless steel HMI enclosures can be used with the CS480 and Compact Series 2 pendant arm systems, Syspend 180-Max and Syspend 281-Max suspension systems.
Hoffman CS480 stainless steel pendant arm system is used to suspend process and control equipment for easy cleaning and wash down. The system’s load rating at 3.3 feet is 89.6 pounds. The CS480 system has a high degree of design flexibility and is recommended for use with the stainless steel HMI enclosures with CS480 pendant cutout.
Products
304 Stainless Steel contains 18% chromium and 8% nickel. It is the most widely used stainless steel within industrial applications. 304 stainless steel resists corrosion and oxidizing agents, which can cause rusting. However, it can tarnish. 304 stainless steel is very strong and can be bent without decreasing the strength, but it can be difficult to manipulate.
Because of its corrosive resistance, 304 stainless steel enclosures are commonly used in dairy plants, mills, bakeries, and many other food processing industries.
316 Stainless Steel. This is a much higher grade of stainless steel containing 16% chromium, 10% nickel and 2% molybdenum, which significantly increases its resistance to pitting and cracking. It has increased corrosive resistance to chloride pollutants, such as salt. 316 stainless steel enclosures are ideal for areas there may have a high salt content, such as coastal areas and areas that use de-icing salts. This type of stainless steel is much more resistant to chemical environments that include sulphuric acid, phosphoric acid or many other chemicals. These types of stainless steel enclosures can be found in areas with high levels of corrosive agents, such as water, wastewater, chemical plants and fertilizer plants. Both 304 and 316 stainless steel enclosures are NEMA 4X rated due to their corrosion resistance, however it is important to remember to never use any chemicals that contain chlorine.
