Dry Rooms

Dry rooms for semiconductor, battery cell and advanced manufacturing require far more than low humidity. These are highly controlled production environments where airborne particulate levels, electrostatic discharge, temperature, pressure, moisture and contamination can directly affect product quality, equipment performance and production yield. CleanSpace designs and delivers ISO 5 and ISO 4 environments engineered around the process, equipment, material flow and exact environmental conditions required for reliable manufacturing.

Our teams bring specialized experience in lithium ion battery production, including electrode manufacturing, cell assembly and the safe segregation of cathode and anode powders. We account for cross contamination risk, powder migration, combustible dust, hazardous material handling, personnel and material flows, cleanability and maintainability from the earliest stages of design. Antistatic materials, conductive flooring, grounding and bonding, ESD controls and carefully selected architectural finishes are integrated into the facility design to protect sensitive products, processes and equipment.

The mechanical systems behind a dry room determine whether it can consistently perform. CleanSpace engineers desiccant dehumidification, high performance air handling, HEPA and ULPA filtration, temperature and humidity control, pressure cascades, process exhaust, heat recovery and environmental monitoring as one coordinated system. Airflow modeling, load analysis and equipment integration help us establish the correct room conditions while balancing energy use, maintainability, redundancy and future production demands.

As a vertically integrated modern design builder, CleanSpace provides one accountable source from initial planning, Basis of Design and digital modeling through engineering, preconstruction, manufacturing, construction, installation, commissioning and qualification. Our teams coordinate the architecture, mechanical systems, controls, utilities and process equipment before work reaches the field, reducing interface risk and creating greater certainty around cost, schedule and performance.

The goal is not simply to construct a classified space. It is to deliver a manufacturing environment that is ready to operate, capable of maintaining its specified conditions and designed to support production from day one. CleanSpace brings design, engineering, construction and compliance together to move advanced manufacturing facilities from concept to operational readiness with greater control and certainty.

What ISO Classification Does Not Define

ISO classification establishes allowable airborne particle concentrations. It does not independently determine:

• Air changes per hour
• Temperature or relative humidity
• Dew point
• Room pressure
• HEPA or ULPA coverage
• ESD and antistatic requirements
• Chemical contamination limits
• Process exhaust requirements
• Personnel gowning protocols

For battery dry rooms, semiconductor facilities and other advanced manufacturing environments, these conditions must be engineered around the product and process. A room may require ISO 5 particulate control while also maintaining an extremely low dew point, anti-static construction, conductive flooring, grounding and bonding, pressure cascades, segregated cathode and anode operations, specialized exhaust and continuous environmental monitoring. CleanSpace’s internal in-house teams have the expertise to ensure the design and engineering are in alignment with manufacturing and operations requires.
