Cold Rooms and General Purpose Freezers
(printable version)
Over the past thirty years, Environmental Specialties (ES) has served the Biomedical and Pharmaceutical environmental chamber market with the cold room series product line designed for uniform and dependable temperature control below an ambient condition. Overall range capability of standard cold room series models is -50°C to +25°C, and chambers can be designed for single point temperature control or variable set points. Sizes vary from "mini" twelve square foot lab step-in units to high bay warehouse storage chambers.
