Rental Dehumidification Solution for Pharma Clean Room Application

Problem Faced by the Customer

The customer operates pharmaceutical manufacturing and clean room facilities in a high-humidity region, where ambient Relative Humidity (RH) frequently exceeds acceptable limits, particularly during monsoon and seasonal weather changes.

The key challenges faced were:

• Inability of existing HVAC systems to consistently maintain validated RH limits (40–55% RH) in clean room areas

• Risk of product quality deviation, especially for hygroscopic materials and moisture-sensitive processes

• Increased chances of condensation, microbial growth, and corrosion

• Potential audit non-compliance under cGMP / WHO-GMP guidelines

• Immediate requirement to stabilize RH without shutting down production or modifying existing HVAC systems

• Given the criticality of operations, the customer required a quick, compliant, and non-capex solution to ensure uninterrupted manufacturing.
