    All HVAC manufacturers must adhere to design and safety standards to ensure the safe operation of their equipment. Tagging HVAC equipment and components with durable nameplates provides essential safety and operating information and allows for unique identification of components for more efficient and accurate preventive maintenance tracking when paired with a preventive maintenance software solution.

    Commercial HVAC applications are harsh environments, however, meaning HVAC equipment requires a highly durable nameplate capable of withstanding abrasion, heat, sunlight, and other environmental conditions to remain readable throughout the lifespan of the asset. That’s why MPC’s Metalphoto® photosensitive anodized aluminum has been the material of choice for HVAC applications for more than 50 years, featuring an image sealed beneath a sapphire-hard anodized layer to resist exposure to chemicals, corrosion, abrasion, sunlight degradation, and extreme temperatures. Because Metalphoto® can meet energy-specific specifications such as OSHA 1910.145, ANSI Z535.4, ISO 3864, National Electric Code (NEC) Article 690, and OSHA 1910.145, commercial HVAC manufacturers have confidence that their equipment nameplates meet all applicable industry standards and best practices.
