EV Battery Facilities The Ardmac Way

ARDMAC

Dry rooms are hermetically sealed rooms that can maintain very low humidity levels while also guaranteeing low particulate concentrations making them an ideal environment for lithium-ion battery production. Specific requirements for such facilities can vary but would typically be ISO Class 6 - 8 cleanroom, with Relative Humidity level of <1% and a Dew Point of -35° to -40° Celsi- us. Regardless of whether it is a small-scale R&D facility or a large scale gi- ga-plant the same design principles will be applied. DRY ROOM DESIGN SOLUTIONS The design solutions specifically required to achieve dry room conditions are made up of 2 critical elements including the architectural envelope and the HVAC system. The architectural envelope is responsible for meeting the requirements in re- lation to the provision of a hermetically sealing room and the HVAC system is responsible for ensuring that the required temperature, humidity levels and particulate concentrations are maintained. While the design principles for dry rooms remain consistent, the project specific design solutions can vary depending on a number of key design variables which include the following:
