Achieving and maintaining ISO Class 5 air cleanliness in 12 operation theatres while reducing energy consumption by 28%.
A major pharmaceutical manufacturer in Goa required ISO Class 7 cleanrooms for a new API manufacturing block. The challenge was achieving ATEX Zone 2 certification while handling 100% outside air during purge cycles.
Existing HVAC equipment was generating 62 dB(A) in adjacent areas and failing to maintain positive pressure during peak production loads. Particle counts were exceeding ISO Class 5 limits during shift changes.
Aerotech CD-200 DIDW fans were selected for their low noise characteristics (82 dB(A) at source, attenuated to 38 dB(A) at room level with acoustic treatment) and HEPA-compatible housing design.
The installation achieved ISO Class 5 certification on the first audit. Energy consumption was reduced by 28% through VFD control and heat recovery from exhaust air.
The facility has maintained continuous ISO Class 5 compliance for 18 months with zero batch rejections attributable to contamination. The NABH accreditation audit specifically commended the HVAC infrastructure.
