Air Handling Unit upgrade saves 58% energy

Finding the right solution

Munters began the upgrade project with an initial site survey to calculate the existing AHU´s power output and airflow.

“We began by analyzing power consumption over the course of seven days” says David Bennett, Service Sales Manager at Munters. “This enabled us to better understand how the AHU was running so we could pick the perfect solution.”

Replacing old fans with a new FanGrid

Munters replaced the AHU fans with a new FanGrid made up of five high-efficiency EC centrifugal plug fans. Besides reducing energy consumption, these fans have reduced maintenance costs for the AHUs, provided better control and reduced noise. The upgrade was carried out with minimal disruption to airport operations.

Result? Substantial savings!
The project has surpassed requirements, with power consumption reducing from 24 kW to 6.4 kW. The airport is predicted to save over £11,000 per year, with a return on investment in 19 months.
