About our products

ELECTRONIC CONTROLS & POWER SAVING SOLUTION

We provide advanced electronic automation and control solutions for HVAC systems including fans, motors, cooling coils, heaters, humidifiers and filtration systems to optimize operational energy consumption.

By installing smart electronic controls, energy savings of up to 50% can be achieved depending on system conditions. The typical payback period for our control solutions ranges from 6 months to 1 year.

Many facilities avoid installing automation due to the high cost of actuators, sensors, controllers and system modifications. SM Airtech provides cost-effective retrofit solutions that can be installed in existing HVAC systems without major layout changes.

HVAC CONTROL LOGIC (FAN AFFINITY LAWS)

Volume Flow Capacity
q1 / q2 = (n1 / n2)

Head or Pressure
dp1 / dp2 = (n1 / n2)²

Power
P1 / P2 = (n1 / n2)³

If fan speed increases by 10%:

* Airflow increases by approximately 10%
* Pressure increases by approximately 21%
* Power consumption increases by approximately 33%

This means that even small increases in airflow demand can significantly increase power consumption and may require electrical system upgrades.
