Form / Attachment / Pricing Sheet

This document provides the specifications for a Controlled Atmosphere Storage System required by the USDA, Agricultural Research Service (ARS), Appalachian Fruit Research Station (AFRS). The system is intended for a horticultural laboratory setting to conduct research and analysis on postharvest storage of pome fruits.

• System Functionality: Create, maintain, and monitor controlled atmospheric environments for fruit samples.
• Modular Design: Must consist of multiple, independent chambers (pods) with individually controllable atmospheric conditions.
• Automated Control: Closed-loop system to automatically measure and maintain user-defined gas concentrations (O2, CO2) by injecting necessary gases.
• Sensing & Logging: Integrated sensors for O2 and CO2 with capability for data logging over time and export (e.g., CSV, Excel).
• Sealed Environment: Hermetically sealed chambers to prevent gas leakage.
• Compatibility: Must be compatible for placement in existing climate-controlled facilities (0-4 degrees C).
• Construction: Durable, clear material (e.g., acrylic, polycarbonate) for visual observation. Compact, stackable design.
• Access Ports: Sealed ports for sample introduction/removal, gas lines, and sensor connections.
• Gaskets & Seals: High-quality, airtight gaskets for doors, lids, and ports.
• Performance: Control ranges for O2 (0.1%-30%) and CO2 (0%-30%) with accuracy of ±0.2% or better.
• Interface: Central controller with an intuitive user interface (e.g., touchscreen).
• Flow Control: Precision gas flow control for nitrogen, CO2, and air.
• Safety: Audible and visual alarms for deviations, gas supply issues, or system errors.

This document outlines the technical specifications and performance requirements for the Controlled Atmosphere Storage System. Bidders must ensure their proposed systems meet all listed requirements to be considered compliant. It details the essential features, materials, and operational capabilities needed for the research objectives.
