Ec technology and intelligent air handling units



Intelligence in the ahu

Intelligence in the AHU

  • Composite unit comprising Fan , Motor and VFD Functionality. (Customer benefits by not having a separate VFD , Motor , Fan )

  • Real time savings due to change in Fan speed ( 10 % Reduction in RPM = 27 % Reduction in Power)

  • Optimum speed of Fan in all condition.

  • Real time Close Loop function. ( Singularly the most important customer benefit of constant temperature , room air quality and pressurization)

  • Eliminates the need for provision of extra air changes thereby increasing efficiency and reducing the cost.


Reduce resource wastage in ahu

Reduce Resource Wastage in AHU

  • Extracting all good of the Centrifugal FAN Design.

  • Even distribution of air inside the Air Handler to maximize the use of Filter Area , Cooling & Heating coils .

  • Increasing life of Filters.

  • Reducing Heat Imparted to the system.

  • Why work at 65 ACPH when 60 is good ?

Reduce Deviation From Limits

  • Upto 80% reduction in Reaction time of the drive to the system dynamics.

  • Conformity to delivery of CFM in the room of upto +/- 5 %.

  • Ability to Scale Up and Down with same efficiency Levels.

    • CFM or Pressure in the room can be scaled upto 25%.

Reduce fault point

Reduce Fault Point

  • Reduces Manual interventions

    • Dampers

    • Room Balancing etc.

  • Life of the system is increased by 100% without maintenance.

Reduce Risk

  • Reduced Amperage => Reduced Heat => Reduced risk

  • Built in fail safe mechanism .

    • Fault Reporting

    • Fail safety activation

    • Start when normalize

  • Built in Harmonic Filtration

Ahu construction made easy

AHU Construction Made Easy


Less components less faults

Less Components ~ Less Faults

With Variable Drive

AECS Inside


Why decide when you can combine in aecs we design the complete system for the client

Why decide when you can combine.In AECS we design the complete system for the client.

With AECS we worry about the combination, Installation warranties and maintenance and above all PERFORMANCE for the whole system.

We are the SPOC


Specific fan power sfp

Specific Fan Power (SFP).

  • AHUs have been traditionally treated as a low tech commodity based on price and not on performance. The current technology is low capital cost and high running/operational expenses. It is in the range of SFP 4- SFP 6.

  • AADTECH has challenged this thinking with its highly energy efficient products and is revolutionizing the industry by making AHUs an intelligent product. Our AHUs are in the range of SFP 1 – SFP 2 which is in the world’s highest efficiency range.

  • With our designed AHUs the customer can get energy efficiency up to 100% higher than conventional system.

  • AADTECH AHUs meet the Energy Efficiency norms mandated by European Union for 2015 ERP norms.


Introduction to specific fan p0wer sfp

Introduction to Specific Fan P0wer (SFP)


ɳ Tot  is the overall efficiency of the driven fan system [-]

DP Tot is the total pressure rise across the fan [kPa]

Mathematically ɳ Tot x SFP = DP Tot

  • The SFP of a system is dependent on

  • The Pressure drop in the system in other words the quality and accuracy of the component level design.

  • Efficiency of the power consuming equipment ie. The Fan and Motor.


Specific fan power sfp1

Specific Fan Power (SFP)

Specific Fan power is a measure of Power used per volume of air = W/CMS

Power – Watts

Volume – Cubic meter second

For Ex.  SFP 1 is more efficient than SFP 5 by upto 400% – 600%.

Categories SFP [W/(m^3/s)]

SFP-1 <500

SFP-2 500-700

SFP-3 750 -1250

SFP-4 1250 -2000

SFP-5 2000 -3000

SFP-6 3000 -4500

SFP-7 >4500

  • P x Q/ Eff = Actual Consumption

  • With our experience we look at the system in totality. Vis~a~vis

    • Dampers

    • Filters

    • Air bending and guiding

    • Specific Fan power

  • We look towards optimizing the system.

    • Why run at 35 ACPH when you can run at 30.

  • Close loop - Our close looping integration makes the drive respond to specific sensors or multiple sensor inputs.

    • 10% CFM = 27% Power
