Custom Air Handling Units (AHU) & Ventilation

Custom Air Handling Units (AHU) & Industrial Ventilation Systems Engineered for India’s Most Demanding Environments

Every industrial and commercial space has a unique air management challenge. Some need contamination-free 100% fresh air. Some need to exhaust toxic fumes from chemical or welding processes. Some need to cool vast, high-bay manufacturing floors. And some need to protect sensitive electrical equipment from heat and dust. Synergy Air Systems designs, fabricates, and installs custom Air Handling Units (AHUs) and heavy-duty ventilation systems that are built precisely around your environment not off a catalogue shelf.

Our AHU & Ventilation Services

1. Double Skin Air Handling Units (AHUs)

Our Double Skin AHUs are fabricated with dual-layer insulated panels that deliver:

• Superior thermal and acoustic insulation, eliminating condensation on panel surfaces
• Rigid structural integrity for installations up to 100,000 CFM (170,000 m³/hr)
• Customizable internal sections: pre-filter, bag filter, HEPA filter, cooling/heating coil, energy recovery, humidifier, fan section, and UV sterilization
• Compliance with ASHRAE, EUROVENT, and SMACNA standards
• Available in floor-standing, suspended, and modular configurations

Designed for pharmaceutical cleanrooms, hospitals, data centres, and large commercial HVAC applications.

2. 100% Fresh Air Handling Units (MAUs / PAUs)

In pharmaceutical and food processing facilities, recirculated air is not acceptable. Our Makeup Air Units (MAU) and Primary Air Units (PAU) deliver:

• 100% outdoor air treated to precise temperature, humidity, and cleanliness standards before delivery to cleanroom secondary AHUs
• Pre-cooling, dehumidification, and reheating sections to manage high-humidity outdoor air in Gujarat’s climate
• Integration with desiccant dehumidification for extreme low-humidity applications
• Designed to handle Gujarat’s peak summer conditions (45°C, 60%+ RH) without performance compromise

3. DX Coil AHU Systems

For projects where a central chilled water plant is not available or practical, our Direct Expansion (DX) AHUs integrate a refrigerant cooling coil directly within the air handler, connected to a remote condensing unit. Applications include:

• Standalone cleanrooms and controlled environment rooms
• Server rooms and telecom exchange buildings
• Remote process areas where chilled water piping is not economical

4. Industrial Exhaust & Ventilation Networks

High-heat, high-fume, or high-dust industrial environments require purpose-engineered exhaust systems. We design and install:

• MCC (Motor Control Centre) Panel Room Ventilation: Positive pressure, filtered supply air systems to protect switchgear and control panels from dust ingress, with sufficient ACH to remove equipment heat load
• Welding Bay & Metal Fabrication Shop Exhaust: High-volume local exhaust ventilation (LEV) to capture weld fumes at source before they contaminate the general space
• Chemical Process Area Ventilation: Corrosion-resistant ductwork and fan systems for areas handling acids, solvents, or other aggressive chemicals with proper dilution ventilation design to keep concentrations below OSHA exposure limits.
• Furnace & High-Heat Area Cooling: Direct Evaporative Cooling For foundries, heat treatment shops, and ceramic kilns, we deploy Direct Evaporative Cooling systems that pass hot air through high-efficiency Honeycomb Cooling Pads, delivering 100% fresh, filtered, cool air at up to 80% less electricity than refrigerated AC. The EVA Series (110-HS to 750-HS) is customisable up to 60,000 CFM with high-static delivery for large shop floors and doubles as a humidification system in dry weather.
• Comfort Cooling for Sensitive Environments: Indirect Evaporative Cooling (Two-Stage) Where low-moisture supply air is critical food processing, industrial kitchens, pharma, or garment factories we specify Indirect Direct Evaporative Cooling (IDEC) via the Evapoler Coolator range. A first-stage polymeric heat exchanger cools incoming air without adding moisture; a second-stage evaporative pad provides further cooling. The result is comfort-level cooling at 60–75% less electricity than conventional AC. The Coolator series (5,000–20,000+ CFM) features IE2/IE3 motors, industrial-grade controllers, and corrosion-resistant cabinets a proven low-OPEX alternative to chillers for large industrial spaces and warehouses.

5. Air Washers & Evaporative Cooling Systems

For large industrial facilities in dry-climate regions like Gujarat, air washers provide the most cost-effective cooling solution:

• Direct evaporative cooling reducing supply air temperature by 8–12°C in Gujarat’s dry summer conditions.
• Suitable for textile mills, garment factories, warehouses, and large manufacturing shops.
• Integrated water recirculation and treatment systems to minimize water consumption.
• Combined with general exhaust systems for cross-ventilation effectiveness.
