Old buildings can often feature outdated and deteriorating ventilation systems. The first opinion may be to replace the entire air handling unit, but often refurbishing the components within the system can prove beneficial beyond financial gain. This week we look at the advantages of AHU refurbishment over replacing the entire system.
One major problem in favour of refurbishment is that of the existing system. Ductwork and max air volume delivery are often governed by the existing ventilation system, so the new one must comply with these specifications. The costs involved with modifying the services, ducting and steel work can be significant. Refurbishing the components is a practical alternative that reduces all of these changes.
The cost of refurbishing an ahu is between 35-50% of the replacement of the entire system. When checked for problems and diagnostics, the component parts are easily installed and transported to the site without the need for cranes and building shut downs.
As component installation is less inconvenient than a whole system replacement, it means less disruption to client operations. With businesses wanting less operation downtime, the procedure saves both time and money. Refurbishment is also much faster than replacing the whole system.
Updating components within an existing ahu also give the opportunity for owners to update the specification of the system. Energy efficient components such as industrial fans and speed controls can contribute to improved profit margins. All centrifugal or axial fans can be replaced but for the latest fans suitable, we suggest you contact us on 01782 349 430.
