Precision Humidity Control for Life-Critical Manufacturing


The Industry Challenge

In pharmaceutical, healthcare, and biotech manufacturing, moisture is not merely an inconvenience it is a direct threat to product integrity, patient safety, and regulatory compliance. Excess humidity accelerates chemical degradation, triggers microbial proliferation, causes tablet capping, and renders APIs ineffective. Drystar India Pvt. Ltd. delivers engineered desiccant dehumidification systems that eliminate this risk with absolute precision.

Key Challenges & Why Change Is Necessary


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

API Degradation

Active Pharmaceutical Ingredients (APIs) are highly hygroscopic. Even marginal humidity excursions can break molecular bonds, reduce potency, and invalidate entire production batches, resulting in massive financial losses and regulatory setbacks.

GMP Non-Compliance

WHO-GMP, Schedule M, and EU-GMP guidelines mandate strict environmental control. Without validated humidity management systems, facilities risk audit failures, import bans, and license cancellations.

Tablet & Capsule Integrity

High humidity causes tablet softening, capping, lamination, and capsule swelling. These defects directly affect dissolution profiles and bioavailability, compromising therapeutic outcomes.

Cleanroom Contamination

Excess moisture promotes mould, fungal spores, and bacterial growth in cleanroom environments, endangering sterile manufacturing zones and contaminating injectable and ophthalmic products.

Lyophilisation Challenges

Freeze-drying processes demand sub-zero dew point environments. Uncontrolled ambient humidity significantly undermines lyophilised performance, cycle times, and final product stability.

The Industry Challenge

GMP regulations mandate strict humidity control at every production stage; non-compliance can trigger facility shutdowns or import alerts. High humidity causes tablet sticking, coating defects, and API degradation, reducing potency and shelf life. Consistent dehumidification is essential for batch quality, product consistency, and regulatory compliance.

  • Integrated filtration, heating, cooling, and dehumidification
  • Seamless HVAC integration with optional energy recovery
  • GMP-compliant stainless steel construction available
  • CE, ISO 9001:2015, ISO 14001:2015, and GMP certified
  • Available in models DIPL-1000 through DIPL-6000

How It Suits This Industry

Pharmaceutical manufacturing demands validated, consistent environmental conditions 24/7. The DIPL Series provides a single-point solution for all air quality parameters temperature, humidity, and filtration simplifying validation documentation and ensuring process repeatability across every shift.

Why This Is the Best Choice

Drystar's DIPL Series is the only integrated system that combines AHU functionality with desiccant dehumidification at pharmaceutical-grade precision. Its GMP-certified construction, 1% RH capability, and full lifecycle support (including AMC contracts) make it the definitive choice for any compliant pharma facility.

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


Product Overview

Designed for large-scale pharmaceutical plants, bulk API manufacturing units, and warehouse-scale storage environments, the Heavy Duty DIPL Series handles air volumes from 8,000 CFM to 15,000 CFM. It combines heavy-duty desiccant rotor technology with automatic controls for stable, continuous humidity management at industrial scale.

Key Features

  • Process air: 8,000 to 15,000 CFM
  • Advanced desiccant rotor with silica gel composition (82% high silica gel)
  • Automatic control systems for unattended, stable operation
  • Durable SS 304 panel construction with powder-coated outer skin
  • Low-noise design suitable for GMP environments
  • Reactivation heater capacities up to 272 KW
  • Approx. weight range: 1,280 to 2,000 KG — engineered for permanent installation

How It Suits This Industry

Large pharma campuses, central sterile supply departments, and bulk storage warehouses require powerful, continuous dehumidification over vast floor areas. The Heavy Duty Series delivers this at scale, maintaining uniform RH across every square metre without operational interruption.

Why This Is the Best Choice

With capacity reaching up to 55,000 CFM across the Drystar range, no pharmaceutical project is too large. The Heavy Duty Series brings the same precision as smaller models to enterprise-scale facilities, backed by Drystar's comprehensive AMC support and automated monitoring capabilities.

Standalone Desiccant Dehumidifier (SDU Series)


Product Overview

The Drystar SDU Series is a compact, portable, and self-contained dehumidification unit designed for smaller pharmaceutical labs, quality control areas, dispensing rooms, and dedicated storage vaults. Available in models from SDU-150 to SDU-2000, it delivers targeted moisture removal exactly where it is needed.

Key Features

  • Process air flow range: 150 CFM to 2,000 CFM
  • Compact and portable — suitable for room-based deployment
  • Open-access design for simple installation and rapid servicing
  • Non-toxic desiccant wheel — safe for pharmaceutical environments
  • Stainless steel body for corrosion resistance and hygiene compliance
  • Single-phase and three-phase power supply options
  • Flexible indoor and outdoor mounting configurations

How It Suits This Industry

Not every pharmaceutical application requires a facility-wide HVAC system. Dispensing booths, material airlocks, sampling rooms, and analytical labs demand precise localised humidity control. The SDU Series delivers this efficiently without the infrastructure cost of a centralised system.

Why This Is the Best Choice

The SDU Series provides pharmaceutical-grade dehumidification in a format that is fast to deploy, easy to validate, and simple to maintain. It is the ideal complement to larger central systems, ensuring no humidity-sensitive area within a facility is left unprotected.
