Why refurbish your AHU?
There are various reasons to refurbish your AHU:
- Refurbishment is ideal where access to the existing AHU is restricted and a new unit is not possible to install
- Deterioration of components and outdated technology is causing poor efficiency and performance
- Space restrictions
- Accessibility restrictions
- Financial restrictions


The benefits of a refurbished AHU
There are many reasons to choose to refurbish your AHU:
- Cost savings – capital costs, running costs and component costs
- Better technology with improved performances
- Reduced downtime and disruption
- Environmental reasons – pollution levels and indoor air quality
Better technology and improved performances
With a refurbished AHU, you can expect to see the following improvements from your system:
- Better degree of thermal conductivity
- Higher filtration levels
- Potential increase in Fan Duty
- Potential increase in external resistance
- Adjustable cooling load requirements
- Leaving air temperature / velocity
- Method of control (Inverters)


Why upgrade to an EC fan?
AC fans are fraught with issues. Pulleys that are not aligned on motors and fans will cause abnormal wear and nuisance breakdowns.
An EC fan contains fewer components, which means less cost and smaller space requirements. An EC fan also provides a reduction in noise and far better efficiencies.
