Certified Precision Humidity Control for the Most Demanding Environments on Earth


The Industry Challenge

Nuclear facilities, defence research establishments, advanced scientific institutes, and government ordnance facilities operate under the most exacting environmental standards in any industry. Humidity infiltration in such environments does not merely cause material damage it can compromise nuclear material integrity, accelerate corrosion of critical components, contaminate sensitive experiments, and pose direct safety risks. Drystar India Pvt. Ltd. delivers ultra-precision desiccant dehumidification systems engineered for these extraordinary requirements.

Key Challenges & Why Change Is Necessary


Understanding the challenges that make a smarter, more reliable solution essential.

Corrosion of Critical Components

Nuclear reactor components, fuel handling equipment, and control systems are fabricated from specialised alloys that are highly susceptible to corrosion at elevated humidity. Even minor moisture ingress can cause catastrophic structural failure over time.

Instrument Calibration Drift

High-precision measurement instruments in research institutes drift significantly in humid environments. Uncontrolled humidity introduces systematic errors in experiments, invalidating years of research data.

Material Degradation in Ordnance

Propellants, explosive compositions, and precision mechanical components in ordnance facilities are highly moisture-sensitive. Humidity-induced degradation poses direct safety and operational reliability risks.

Contamination of Clean Environments

Research facilities handling radioactive materials, isotopes, and sensitive biological or chemical samples require absolute environmental stability. Moisture is a vector for contamination that cannot be tolerated.

Documentation and Audit Requirements

Nuclear and defence facilities operate under DAE, DRDO, and international safety authority oversight. All environmental control systems must be validated, documented, and maintained to an exacting standard.

The Industry Challenge

Humidity fluctuations corrupt sample integrity, damage precision instruments, and compromise experimental results. In nuclear facilities, moisture accelerates corrosion in containment structures and affects radiological material behaviour. Clean room environments demand simultaneous particulate and humidity control for critical research and safety.

Standalone Desiccant Dehumidifier (SDU Series)


Product Overview

For research laboratory rooms, instrument calibration chambers, sample storage vaults, and small enclosed spaces within nuclear or research facilities, the Drystar SDU Series provides precision dehumidification in a compact, self-contained, and easily validated format.

Key Features

  • Process air: 150 to 2,000 CFM for targeted, room-level control
  • Ideal for instrument rooms, sample preparation labs, and archive storage
  • Compact footprint deployable within existing room configurations
  • Nontoxic desiccant wheel safe for sensitive research environments
  • Easy validation and documentation for audit purposes
  • Robust SS body for long service life in regulated environments
  • Available in single phase for laboratory power configurations

How It Suits This Industry

Not every space within a nuclear or research facility requires facility-scale dehumidification. The SDU Series allows targeted, validated humidity control at critical sub-environments- calibration labs, archive rooms, sample storage without requiring centralised infrastructure.

Why This Is the Best Choice

The SDU Series' simple, validated design and minimal maintenance requirements make it an ideal fit for research environments where operational complexity must be minimised. Its compact format and flexible placement allow deployment in virtually any room configuration.
