Engineering company ECEX has published a guide to air handling unit (AHU) refurbishment.
Managing director John Grenville said: "Conventional wisdom dictates that air handling units (AHUs) should be replaced every 10 to 15 years, depending on use and maintenance over that time. There is, however, a potentially far more cost-effective way to proceed than replacement - refurbishment and/or upgrade.
Ryan Hawken, ECEX contracts manager and AHU specialist, commented: “The savings associated with air handling unit refurbishment can be dramatic. For example, on a recent AHU upgrade project, we calculated that we could provide an estimated 22% – 33% energy saving simply by upgrading the fans.
“There were also additional savings as belts and pulleys would no longer need replacement, as well as much reduced maintenance time.”
