As more building operators opt for a refurbishment strategy rather than replacement, Envirotec has reported a sharp increase in demand for its comprehensive refurbishment service for air handling units (AHUs).
“Even 20-30 year old AHUs can be successfully refurbished with a major improvement in performance – and the financial and environmental savings are very significant,” explained Envirotec’s Ron Flewett. “Our experience over many years of refurbishing AHUs is that savings, compared to buying new units, typically range from 20% to 50%. Furthermore, the end user will benefit from additional life cycle cost savings through reduced maintenance costs and improved energy efficiency, as well as adopting a more sustainable strategy,” he added.
The scope of an AHU refurbishment can range from replacement of components with modern, more efficient designs through to replacement of whole sections or addition of new sections. The latter option enables duties to be increased very cost-effectively, perhaps in response to changes in building usage.
In addition, a well-planned refurbishment will be less disruptive to the building’s occupants, as the work can be planned in phases. Refurbishment is also often a popular option where access to existing plant is difficult.
