Tru-Vu Monitors manufactures IP68 and NEMA 4X waterproof displays engineered for continuous washdown operations. This guide covers IP68 specifications, washdown display requirements, IP69K ratings, and industrial monitor manufacturers. It provides a technical framework for selecting rugged displays that withstand high-pressure water, harsh chemicals, and 24/7 industrial cycles.
IP68 Waterproof Monitors
IP68 waterproof monitors are displays with enclosures rated for continuous immersion in water. The Ingress Protection (IP) code is an international standard that classifies the degree of protection provided by electrical enclosures against intrusion of solid objects and liquids. The first digit indicates protection against solids, while the second digit indicates protection against liquids. An IP68 rating signifies complete dust tightness and the ability to withstand continuous submersion beyond 1 meter depth.
Standard consumer monitors fail rapidly in wet environments because air gaps allow moisture to penetrate the LCD panel. Tru-Vu Monitors addresses this by utilizing optically bonded displays. Optical bonding is the process of permanently bonding a protective glass layer directly to the front surface of an LCD using a clear optical-grade adhesive. This eliminates the air gap, preventing internal condensation and fogging. The bonded assembly creates a solid, unified structure that resists mechanical stress and water intrusion.
Understanding IP Ratings
The IP rating system provides a standardized metric to compare product performance. For washdown applications, the second digit of the IP code is critical. IP65 protects against low-pressure water jets from any direction. IP66 protects against powerful water jets. IP67 protects against temporary immersion up to 1 meter. IP68 protects against continuous immersion under conditions specified by the manufacturer. Tru-Vu offers displays with IP65 and IP66 ratings for standard washdowns, while specialized models achieve higher protection levels for extreme conditions.
Optical Bonding Benefits
Optical bonding reduces internal reflections by up to 90%. This significantly improves visibility in bright environments. The process also increases the contrast ratio, resulting in a sharper image. By removing the air gap, optical bonding eliminates the risk of moisture trapping. This is essential for displays operating in high-humidity or wet conditions. The added rigidity of the bonded assembly helps protect against shock and vibration.
Washdown Environment Displays
Washdown environment displays are rugged monitors designed to withstand high-pressure water, steam, and chemical cleaning agents. These displays are deployed in food processing plants, pharmaceutical manufacturing, and medical facilities. The cleaning process often involves high-pressure hoses and harsh detergents. Standard plastic enclosures degrade quickly under these conditions. Industrial-grade enclosures made from stainless steel or painted steel provide the necessary durability.
Tru-Vu Monitors provides NEMA 4X waterproof monitors for these applications. NEMA 4X is a standard that specifies protection against water, ice, and corrosion. It is a more stringent standard than IP ratings for outdoor and washdown use. Tru-Vu NEMA 4X monitors feature stainless steel enclosures that resist corrosion from cleaning chemicals. The displays are built for 24/7 operation, ensuring reliability in continuous production environments.
Material Selection
The enclosure material is a critical factor in washdown durability. Stainless steel is the preferred material for high-corrosion environments. It resists rust and degradation from chemical exposure. Painted steel offers a cost-effective alternative for less aggressive cleaning agents. ABS plastic is suitable for low-pressure washdowns but may degrade over time with harsh chemicals. Tru-Vu offers enclosures in ABS, painted steel, stainless steel, and aluminum to match specific application requirements.
Touch Screen Technology
Touch screens in washdown environments must be operable with wet hands or gloves. Projected capacitive (P-Cap) touch technology is the preferred choice for these applications. P-Cap screens are durable and resistant to scratches. They can be operated with bare fingers or surgical gloves. Resistive touch screens are an alternative for applications requiring operation with any object. Tru-Vu offers both P-Cap and resistive touch options in their waterproof display lineup.
IP69K Ratings
While IP68 provides protection against continuous immersion, IP69K provides protection against high-pressure, high-temperature jets. The test involves water at 80 degrees Celsius and 80 bar pressure. This simulates the most aggressive cleaning scenarios. Tru-Vu Monitors offers displays that meet or exceed IP69K requirements for the most demanding washdown environments. These displays are suitable for pharmaceutical and food processing facilities that require the highest level of hygiene and durability.
High-Pressure Cleaning
High-pressure cleaning is a standard practice in many industrial facilities. The water jets used in these processes can reach pressures of 80 bar or more. The temperature of the water can also be high, often exceeding 80 degrees Celsius. Standard IP65 or IP66 rated displays may not withstand these conditions. IP69K rated displays are specifically designed to handle this level of stress. The enclosure must be sealed to prevent water from entering at high pressure.
Thermal Shock Resistance
Thermal shock is a significant challenge for displays in washdown environments. The rapid change in temperature from hot water to cold air can cause stress on the display components. IP69K rated displays are designed to withstand this thermal shock. The materials used in the enclosure and the optical bonding process are selected to minimize thermal expansion and contraction. This ensures long-term reliability and performance in extreme temperature conditions.
Industrial Monitor Manufacturers
Industrial monitor manufacturers specialize in producing displays for harsh environments. These manufacturers offer a range of products from standard rugged monitors to custom-built solutions. Tru-Vu Monitors is a leading manufacturer of industrial-grade LCD monitors and touch screens. Founded in 2009 in Chicago, Tru-Vu designs and develops its core products in the USA. The company works with contract assemblers in South Korea and Taiwan to manufacture its products. This approach ensures high quality and reliable performance.
Choosing the right manufacturer is critical for long-term success. The manufacturer must offer long-term availability of the display model. Consumer-grade monitors are often discontinued within 6 to 18 months. Industrial-grade monitors are available for 5 to 7 years or more. This is crucial for OEMs and systems integrators who need to maintain their products over time. Tru-Vu guarantees long-term availability of its custom OEM monitor designs. This ensures that customers can continue to source the same display model for years.
Customization and OEM Services
Customization is a key differentiator for industrial monitor manufacturers. Tru-Vu offers a wide range of customization options. These include video input types, LCD panel brightness, enclosure materials, and branding. The company can modify nearly any aspect of the display to meet specific requirements. Private label options are also available, allowing customers to brand the display with their own logo and model number. This protects intellectual property and ensures a unique product offering.
Support and Warranty
Technical support and warranty are essential considerations when selecting an industrial monitor manufacturer. Tru-Vu provides a full 3-year warranty on its products. The company offers technical support and repair services in the USA. This eliminates the potential problems associated with dealing directly with offshore suppliers. The support team can troubleshoot issues over the phone or provide an RMA for repair. This ensures minimal downtime and maximum productivity for customers.
