AeroTech's Floor Mounted Air Handling Unit (AHU-FM Series) is a large, modular device that conditions and circulates air in buildings, regulating and circulating air by filtering, heating, cooling, and dehumidifying it before distributing it through ductwork. The modular framework is made of anti-corrosive extruded aluminium profile available in Thermal Break or Non-Thermal Profile. Standard 25mm/43mm panels are made of prepainted/precoated/GSS sheets injected with environment-friendly PUF of uniform density of 40±2 kg/m³.
High energy efficient forward/backward curved aerofoil AMCA certified centrifugal fans are available for all applications. The fan and motor is mounted on a common channel fitted with anti-vibration isolators. We offer a wide range of chilled water, direct expansion, hot water, and steam coils up to 12 rows deep, each pressure tested at 21 kg/cm² under water.
The unique SS-304/Aluminium drain pan with multi-slope ensures complete drainage and prevents microbial growth. Fully sealed filter sections designed for easy installation and removal. Fresh air and return air can be mixed at desired rates with manual or motorized aluminium aerofoil dampers.
Available from 1,000 CFM (AE-010-FMU) to 40,000 CFM (AE-400-FMU) with 18 standard models. BMS compatible integration. Suitable for hospitals, pharmaceutical facilities, cleanrooms, R&D labs, industrial applications, hotels, shopping malls, and government establishments.

Industrial Air Handling Units are typically engineered for a chilled water Delta-T (temperature differential) of 10°F to 12°F (e.g., entering at 44°F and leaving at 54°F). Maintaining this exact Delta-T ensures the coil effectively strips latent heat (humidity) without causing the central chiller plant to operate inefficiently (Low Delta-T syndrome).
To prevent moisture carryover into the supply ductwork, the maximum face velocity across a standard AHU chilled water coil should not exceed 500 Feet Per Minute (FPM). If spatial constraints require higher velocities, specialized droplet eliminator plates must be installed downstream.
Dual enthalpy sensors measure both the temperature and humidity of the outside air versus the return air. When the outside air is cooler and drier than the indoor air, the BMS opens the outside air dampers to 100%, providing 'free cooling' and completely shutting down the mechanical chillers.
Yes, retrofitting standard AC motors with Electronically Commutated (EC) plug fans in an Air Handling Unit (AHU) is one of the fastest ways to improve HVAC energy efficiency. EC motors can reduce AHU brake horsepower consumption by up to 50% during partial load conditions.
Opposed Blade Dampers (OBD) feature adjacent blades that rotate in opposite directions. Unlike parallel blade dampers which throw air to one side of the duct, OBDs maintain a straight, laminar airflow profile even when partially closed, making them mandatory for precise volumetric balancing in AHUs.
