In the pharmaceutical industry, maintaining precise environmental conditions isn’t just important—it’s mandatory. When dealing with sensitive processes, the air must be clean, temperature-controlled, humidity-regulated, and contamination-free. That’s where Double Skin Air Handling Units (AHUs) come into play. Designed specifically for pharmaceutical and critical industry applications, these specialized AHUs from leading manufacturers like Shree Bhagwati ensure that your facility consistently complies with stringent hygiene standards, ultimately safeguarding product quality and patient safety.
What is a Double Skin Air Handling Unit (AHU)?
A Double Skin AHU is a sophisticated HVAC system with two layers or ‘skins’ of metal separated by an insulating material, typically PUF (Polyurethane Foam) or rock wool. This design significantly improves thermal efficiency, reduces noise, and prevents air leakage. Specifically tailored for pharmaceutical environments, these AHUs provide meticulously controlled airflow, filtration, temperature, and humidity. By ensuring precise air quality, they maintain the sterile conditions essential for pharmaceutical manufacturing, research labs, hospitals, and other cleanroom facilities.
Core Features of Double Skin AHUs
Double Skin Casing and Insulation
Double skin construction is central to the effectiveness of these AHUs. With a casing thickness of 25/43 mm filled with high-density PUF insulation, these units maintain energy efficiency, reduce operational noise, and limit heat transfer. This dual-layer insulation ensures stable internal temperatures, vital for sensitive pharma processes where even minor fluctuations can impact product quality.
High Airflow Capacity for Pharmaceutical Facilities
Pharma-grade AHUs are engineered to support high-capacity airflow, up to 40,000 CFM, making them ideal for large-scale pharmaceutical production facilities. High-capacity airflow ensures consistent air circulation, reducing the risk of contamination and maintaining a controlled environment even in extensive manufacturing areas.
Advanced Multi-Stage Filtration System
Air purity is non-negotiable in pharmaceutical environments. The multi-stage filtration process involves a pre-filter to remove larger particles, a fine filter to eliminate smaller contaminants, and optional HEPA filters for achieving the highest air purity standards. HEPA filtration ensures air purity up to 99.97%, removing microscopic particles down to 0.3 microns, essential for sterile and contamination-sensitive environments such as vaccine production or biotech laboratories.
Flexible Configuration Options
Double Skin AHUs are not one-size-fits-all solutions; they come in flexible configurations tailored to specific facility requirements. They can be floor-mounted for easy access, rooftop-installed to save space, or modular for expansion and flexibility. Selecting the right configuration ensures optimal efficiency, ease of maintenance, and seamless integration into your existing infrastructure, ensuring uninterrupted productivity in pharmaceutical processes.
Materials and Construction: Ensuring Hygiene and Durability
Stainless steel construction (SS 304/316) is optional for internal parts, ensuring unmatched corrosion resistance, cleanliness, and durability. SS construction provides long-term reliability in corrosive pharmaceutical environments, facilitates ease of cleaning, and prevents microbial buildup, thus meeting stringent GMP and WHO compliance standards. Its resistance to corrosion and chemical exposure is particularly crucial in API manufacturing or formulation areas, safeguarding both products and equipment longevity.
Floor Mounted Stainless Steel AHUs for Pharmaceutical & Cleanroom Operations
While Double Skin AHUs are widely used for high-efficiency HVAC control, many pharmaceutical and cleanroom facilities also require Floor Mounted Stainless Steel AHUs for specialized applications that demand maximum hygiene, structural stability, and easy accessibility. These units are engineered to deliver precise control over airflow, temperature, humidity, and contamination levels—making them a trusted solution for critical environments in pharma, biotech, hospitals, electronics, and high-purity industrial processes.
Constructed using SS 304 or SS 316 stainless steel, these units offer exceptional corrosion resistance, microbial control, and ease of cleaning. Their floor-mounted configuration ensures stable placement, effortless maintenance access, and seamless integration into cleanroom layouts where space utilization and sterility are top priorities.
Key Features of Floor Mounted SS AHUs
Robust and Hygienic Stainless-Steel Construction
Made from SS 304/316 or PPGI insulated panels, these AHUs provide long-term durability, superior cleanliness, and resistance to corrosion-ideal for environments that cannot tolerate contamination.
Advanced Multi-Stage Filtration
Equipped with pre-filters, fine filters, and optional HEPA/ULPA filters, Floor Mounted AHUs ensure micro-level filtration that complies with ISO 14644 cleanroom standards, WHO guidelines, and GMP norms. These filtration stages remove dust, microorganisms, and airborne contaminants critical to sterile environments.
Modular Floor-Mounted Design
Designed for precise alignment and easy servicing, the modular design allows quick installation in new projects or existing facility upgrades. Tool-free panels simplify maintenance processes.
Efficient Heating & Cooling Coils
Copper or aluminum coils support chilled water, hot water, DX, or steam-based conditioning to maintain precise temperature and humidity levels across pharmaceutical and industrial processes.
Custom Airflow and Sizing
Units are available in multiple standard dimensions such as 6×4, 8×4, 8×6, 8×8, 10×8, and 10×10, with fully tailor-made options depending on CFM requirements, room load, and desired ACH (Air Changes per Hour).
Smart Sensors and Control Capability
Integrated sensors for temperature, humidity, differential pressure, and airflow allow accurate control. These systems can be configured for PLC or BMS integration, enabling real-time monitoring and automated performance adjustments.
Airflow Monitoring & Pressure Control
Ensures consistent, balanced airflow across cleanroom classifications while maintaining positive or negative pressures as required for sterile manufacturing.
