Ventilation Industries

Air Technology Systems specialise in providing efficient Industrial Ventilation Solutions to the Water, Waste & Composting Industries.

Water & Sewage

Air Technology Systems have a wide range of applications including but not limited to cooling of plant with significant loads such as:

  • Pump halls and MCC Rooms
  • Condensation prevention such as in RGF and GAC filter buildings
  • Transfer of heat for free heating
  • Background Ventilation of chemical rooms including chlorine, sodium hydroxide, sodium hypochlorite, fluoride, ozone etc
  • Capture and containment of odours via both general supply extraction push-pull systems, and via direct connections to plant and processes

The main challenge on water and waste sites is the important level of specifications and standards required. Therefore, we often collaborate closely with our client to provide a solution that complies with the specification.

There are also greater limitations on budget available, which requires us to provide an effective solution that falls within the specified budget.

Finally, we are often working within existing buildings,  which provides an additional set of constraints, on where equipment can be positioned and how we can achieve the basis of design.


We come across similar applications with waste and water sites.

The main challenge seen across Energy from Waste (EfW) and Refuse Derived Fuel (RDF) sites are a combination of very high heat loads in conjunction with large, congested plant rooms.

We therefore need to move large volumes of air not just into a room, but around large vessels, conveyors, and other plant, where there is little to no free space within the building for Ventilation equipment.

We can overcome this with a combinations of strategically placed supply fans and transferring internal systems to minimise hot spots or dead zones.

Composting Facilities

Due to the processing, composting facilities have very high temperature, high humidity areas.

The introduction of air, with no tempering or conditioning, to such an atmosphere will create large clouds of condensate, as the cooler external air lowers the internal temperature to below the dew point. This obscures vision for operators and corrodes plant and the building structure.

Air exhausted from the tunnels is typically up to 80°C, which contains both high water content and significant odours and contaminants. Therefore, material selection is important for these sites.

In-Vessel Coposting (IVC) plants are one of the most important facilities to consider both the Odour Control treatment and the Ventilation of the areas as a combined approach.
