Before & After Refurbishment

A world of difference

See the impact our Site Engineering Services (SES) department can have. This 25-year-old AHU was well past its best. Internal and external upgrades and modifications were desperately needed. So our SES team:

  • Updated the appearance by installing smart new external panels
  • Replaced old belt-drive AC fans with new energy-efficient EC motors
  • Fitted a new gas burner and DX coils
  • Installed replacement filters and a new control package


What’s included in your refurbishment service?

We can supply and install all necessary components as part of your air handling unit refurbishment. We will also remove old or damaged items, schedule work at your convenience (even weekends), and arrange for flat-pack new components when installation is required in hard-to-access areas.

What parts of an air handling unit can be refurbished?

Almost every part of an AHU can be refurbished by Air Vent Technology’s experienced team. This includes panel filters, bag filters, heating and cooling coils, fan and motor assemblies, belt and pulley drives, plug fans, and attenuators.

How much money can we save by refurbishing our AHUs?

Compared to buying and installing new AHUs, the costs of refurbishment are significantly cheaper. Some businesses have saved up to 50% compared to the costs of completely new units. And because refurbishment leads to improved AHU performance, you also save on running costs.

Besides costs, why else should we consider refurbishing AHUs?

AHU refurbishments offer a huge range of benefits, including quicker installation times, reduced plant downtime, lower carbon emissions, ongoing alignment with legislative changes, and easy coordination with other trades.
