Since the late 1960's, Harris Environmental has specialized in providing close tolerance control temperature and humidity environmental rooms supplied to our clients as a turnkey system. Complete “single source responsibility” of all aspects of each room including the room structure, mechanical systems, and controls are provided for every project. Life Science research, Drug Discovery, Pharmaceutical R & D, pilot plant production, or full biopharmaceutical manufacturing all require specific environmental rooms for product development, stability testing, and production. At Harris, we provide many walk-in cold rooms, freezers and incubators, but we also specialize in modular dry rooms, D/H series custom dehumidification systems, clean rooms, cycling chambers, and archival storage vaults.
