This document outlines the Commercial Item Description (CID) for Tumbler-Dryer machines designed for Naval shipboard use, specifying the requirements for 50-pound and 100-pound capacity steam and electric dryers. Key features include a corrosion-resistant housing, manual temperature controls, safety mechanisms such as thermal limit sensors, and a cooling cycle post-drying. The dryer units must be compact enough to fit through specific ship access points and should maintain operational integrity under shipboard conditions, including vibration and motion. The performance specifications require the dryers to effectively remove moisture from heavily soaked clothing, demonstrating high drying efficiency. Electrical components must comply with standard safety regulations, ensuring minimal leakage current and robust insulation. The document emphasizes the importance of using durable materials, including stainless steel, malleable iron, and heat-insulated components, to enhance reliability and safety. Overall, the CID serves as a guideline for manufacturers responding to government Requests for Proposals (RFPs) and grants, ensuring that produced dryers meet strict military standards and can withstand the demanding environment of naval operations.
