Protecting India's Critical Power Assets with Industrial-Grade Humidity Control.


The Industry Challenge

Power generation plants, electrical switchyards, transformer stations, cable tunnels, and critical infrastructure facilities are in a constant battle against humidity. Moisture causes insulation breakdown, accelerates corrosion of electrical conductors and structural steel, triggers condensation in switchgear, and dramatically shortens the service life of expensive power plant equipment. Drystar India Pvt. Ltd. delivers proven industrial dehumidification solutions that protect India's power infrastructure reliably and efficiently.

Key Challenges & Why Change Is Necessary


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

Electrical Insulation Degradation

Moisture is the primary cause of dielectric strength reduction in transformer oils, cable insulation, and switchgear components. Humidity-induced insulation failure causes costly outages and poses serious electrocution risks.

Corrosion of Structural & Electrical Components

Steel structures, bus bars, cable trays, and control panels corrode rapidly in humid environments, increasing maintenance costs and reducing equipment lifespan from decades to years.

Condensation in Control Rooms

Temperature differentials between outdoor and indoor environments in control buildings cause condensation on panels, relay boards, and SCADA systems, leading to false trips, equipment damage, and operational instability.

Generator and Turbine Downtime

Moisture ingress into generator windings, turbine housings, and auxiliary systems during standby periods causes damage that requires expensive rewinding and refurbishment before restart.

Cable Vault and Tunnel Deterioration

Underground cable vaults and tunnels accumulate moisture that accelerates cable sheath degradation, joint failure, and ground fault incidents all of which cause extended supply interruptions. Power generation plants, electrical switchyards, transformer stations, cable tunnels, and critical infrastructure facilities are in a constant battle against humidity.

Moisture causes insulation breakdown, accelerates corrosion of electrical conductors and structural steel, triggers condensation in switchgear, and dramatically shortens the service life of expensive power plant equipment.

Industrial AHU Cum Desiccant Dehumidifier (DIPL Series) or Vertical AHU cum Dehumidifier (V series)


Product Overview

The Drystar DIPL Series is deployed across power plant auxiliary buildings, control rooms, switchyard equipment rooms, and electrical sub-stations to maintain controlled humidity environments that protect electrical assets from moisture-related damage.

Key Features

  • Process air: 1,000 to 6,000 CFM for mid-scale power facility zones
  • Maintains RH below 50% in electrical equipment rooms
  • Integrated temperature control for consistent conditions year-round
  • Compatible with existing HVAC in power plant buildings
  • CE, ISO 9001:2015 certified, suitable for utility-grade applications
  • Automated operation with building management system integration
  • AMC support for continuous operational reliability

How It Suits This Industry

Power generation facilities encompass multiple buildings with different dehumidification requirements. The DIPL Series' modular range allows Drystar to design tailored solutions for control rooms, cable spreader rooms, battery rooms, and auxiliary equipment areas within a single power plant.

Why This Is the Best Choice

Power plant operators require systems that run continuously without attention. Drystar's DIPL Series, backed by structured AMC contracts and 24/7 support availability, provides exactly this ensuring humidity control systems never become a source of plant downtime.

Heavy Duty Industrial AHU Cum Dehumidifier (DIPL-8000 to DIPL-15000)


Product Overview

Large coal-fired, gas, nuclear, and hydro power plants require powerful dehumidification across enormous enclosed spaces including turbine halls, generator halls, and switchyard equipment buildings. The Drystar Heavy Duty DIPL Series provides the industrial-scale air handling capacity for these environments.

Key Features

  • Process air: 8,000 to 15,000 CFM
  • Engineered for 24/7 continuous operation in harsh industrial environments
  • Handles high latent heat loads typical of large power plant halls
  • Durable, heavy-duty construction for long service life
  • Low noise operation compatible with occupied control buildings
  • Remote monitoring and alarm integration for utility operations centres
  • Full documentation for utility regulatory compliance

How It Suits This Industry

Turbine halls and generator buildings in major power plants contain billions of rupees of equipment that must be protected from moisture continuously. The Heavy Duty DIPL Series is the only Indian-manufactured system with the capacity and reliability credentials to fulfil this responsibility.

Why This Is the Best Choice

Siemens, Alstom, and other global power engineering companies have trusted Drystar systems as part of their Indian project deployments. This endorsement from global OEMs validates Drystar's engineering quality and reliability credentials for the power sector.
