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.

Small-scale research

Pilot plants

Mega / Giga-factory

Single-zone facilities for testing the chemicals and processes during battery R&D.

Multi-zoned facilities for scaling up production to manufacture at volume.

Large-scale battery production facilities for high-volume battery production.

Solid state battery dry room

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.

Lithium ion battery dry room

Lithium battery dry rooms

Lithium Battery Dry Rooms requires specialist desiccant dehumidifiers capable of producing ultra low dewpoint air as low as minus 70. Working with our industry-partner DRY-AIR, our systems can efficiently achieve these requirements.


As a cleanroom specialist, our dry rooms can also achieve ISO classification. Not only that, but they can also meet any applicable international engineering and building standards and regulations.

We've developed proven envelope solutions and reliable cleanroom HVAC designs for many applications. As part of the Angstrom Technology group of companies, we pride ourselves on our in-house expertise and capability to deliver over 100 cleanrooms annually across the UK, Europe, and America.
