nVent Hoffman SYSPEND Sanitary HMI Enclosures
nVent Hoffman’s SYSPEND sanitary HMI system is an enclosure and suspension system designed to protect, enclose and suspend lightweight HMI devices. The modular system specifically meets the demanding needs of sanitary environments, particularly the food and beverage manufacturing industry.
nVent Hoffman stainless steel SYSPEND sanitary enclosure is made of 18 gauge Type 304 stainless steel and is designed to house process control equipment in sanitary wash down environments. The enclosure meets Type 4X and IP69K requirements for high-temperature, high-pressure wash down applications. The 20 degree sloped top allows for runoff of water and cleaning solutions and the integrated side handles allow for easy repositioning of the enclosure. The enclosure can be mounted on a pendant or pedestal and a suspension arm adaptor is included.
nVent Hoffman SYSPEND aluminum HMI enclosure is designed to accommodate touch-screen HMI devices. The single-walled aluminum reduces the overall weight of the enclosure and provides increased heat dissipation. The enclosure can be mounted on a pendant or pedestal and the integrated side handles allow for easy repositioning.
Stainless Steel Enclosures: Type 304 vs 316
304 Stainless Steel
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
316 Stainless Steel 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 have a NEMA rating of NEMA 4X because they are corrosion resistant, however it is important to remember to never use any chemicals that contain chlorine.
