Battery Dry Rooms
Humidity control is critical in battery dry rooms as various materials and processes used in battery production are susceptible to moisture damage. Connect 2 Cleanrooms can create a stable low dewpoint production environment to meet your requirements.
Battery dry room construction
Battery dry rooms require a constant supply of ultra-dry air to create and maintain low-humidity conditions for the R&D and production of solid-state and lithium-ion batteries.
We can develop an energy-efficient dry room to protect your critical process by combining airtight envelope systems, dehumidification systems, and HVAC design.

Battery dry room manufacturers
As battery dry room facility manufacturers, we deliver complete dry room systems. We provide bespoke solutions that include industry-leading energy-efficient HVAC systems.
A typical clean room environment operates at 20.0°Cdb, 50% Relative Humidity, which equates to a dewpoint of 9.3°Cdp. Due to material sensitivity, solid-state battery dry rooms can require control to minus 40.0°Cdp at the room's exit point. With a dewpoint control of minus 50.0°Cdp now required for Lithium-ion battery dry rooms, the next generation may have even tighter requirements. The battery chemistry may need the environment to reach minus 80.0°Cdp at the point of supply into critical areas, such as Electrolyte Fill.
