Application and configuration
Use only for materials whose storage requirements fall within the stated temperature range. Confirm the required usable capacity, container layout, ambient conditions and installation clearances before ordering. Energy consumption, uniformity and holdover figures apply to the stated test conditions. Confirm rack, cryobox and tube compatibility for the selected configuration. Where fitted, the controller backup battery does not power the cooling system.
