care to ensure optimum performance – from both an airflow and an indoor air quality perspective.
At some point the air-handling unit’s performance will start to diminish – much more quickly so if it isn’t regularly serviced. We know that our NHS is under financial strain, and budget and practical restraints often mean that replacing a complete unit isn’t an option.
Furthermore, it isn’t always necessary, but not all manufacturers will tell you that.
Fan upgrade option
An option that is often overlooked is that of an upgrade. A fan upgrade is pretty much what it says on the tin – replacing older, less economical fans with shiny new, more efficient fans. It can also include upgrading other elements of the AHU, such as casings and doors, without changing the whole unit, to keep it looking fresh, and, most importantly, operating at maximum efficiency to keep the air fresh and maintaining its ability to meet the HTM 03 guidance. Upgrading is

a cost-effective offer that is attractive to many healthcare providers, where access to the AHU is restrictive, and closing down part of a site isn’t really viable. The cost of refurbishment can often be offset against the energy expenditure of an inefficient unit; something which can in turn help the environment, the patient, and the person who pays the energy bill. It does seem that being more mindful of what we do, how we manage our equipment, and what the full lifespan cost of an AHU, or any other piece of equipment, for that matter, is, will have a more positive impact on the environment, and in turn our pocket. However, it does require some effort – a change in the way things have been done historically perhaps; perhaps some outlay upfront. Selecting a supplier that has undertaken much of the research can really take the pain out of this change, and make lifespan savings for both the planet and the client, while providing consistently improved air quality that meets government guidance standards for the plant’s full lifecycle. hej
Air supply needs checking to ensure that it is both healthy and comfortable, and the units in general need an occasional bit of attention and care to ensure optimum performance
