Small businesses are invited to quote on a firm-fixed-price purchase order to supply and deliver two complete direct-space humidification systems for CDC laboratory spaces. The systems must include all required materials and components, with Smart Fog equipment as the design basis; technically acceptable equal products will be considered. Installation, air compressors, control wiring, and utility connections are excluded from the requirement. Delivery is required within 10 business days after award, with partial deliveries permitted, to the CDC Distribution Center at 3719 North Peachtree Road, Chamblee, GA 30341-2221. Award will be made using a best-value tradeoff approach, with technical capability significantly more important than price.
