There are many internal environments that need a controlled atmosphere. Recent developments in both vertical farming and smart commercial greenhouses are creating great interest across the world and here in the UK. The desire to create these indoor environments is driven by the need to increase crop yields of fast-growing, high-value low-biomass crops such as herbs, salads, small fruits, and vegetables. However, growing food in a factory-style environment does require efficient and effective control of air quality and temperature to optimise growth and improve crop productivity. The controlled air flow needed for vertical farms will be delivered from one or several air handling units (AHUs), drawing in fresh air from the outside to help enhance photosynthesis and promote plant growth. This is where AirCraft Air Handling [...]

Everyone at AirCraft Air Handling would like to thank all our customers, partners and those who have shown interest in our business over the past year for bringing us the many high-specification AHU projects we have been asked to assist with during 2024.

Packaged DX (Direct Expansion) AHUs, what are they and their advantages? A packaged DX AHU is an all-in-one air handing unit (AHU) also known as a plug and play unit that controls and circulates the air within a building. They are designed and manufactured as a self-contained unit that includes heating and cooling modules, fans, filters and a control system to provide managed ventilation, heating, and temperature-controlled air flow. The Advantages Aircraft Air Handling’s packaged DX AHUs are all individually specified, designed and manufactured to each customer’s own site-specific requirements. Supplied as an all-in-one unit, our packaged DX AHUs only require minimal on-site assembly and connection to the building’s electrical supply and air ducting system. This significantly reduces installation time, potentially removing the need to have [...]

Have you a problem with an aging air handling unit (AHU), or just want to keep your end-of-life AHU running for a few more years? AirCraft Air Handling might just be able to help. An old, even plus 35-years-old, AHU may still work, but it is more likely to breakdown and require new parts. These parts might not be available from the original manufacturer, either because they no longer produce parts for that AHU, or the manufacturer themselves are no longer in business. It is possible that you may also not be able to see the manufacturer’s markings anymore. So, an easy way to establish if we can help is to use your phone to photograph the failing part. Simply send the image to us by [...]

Air Handling Units (AHUs) tend to have their airflow configuration in a horizontal direction, but there are some instances where a vertical AHU is needed instead, depending on the area it will be installed in. This was the case for a medical technology company, located in western UK, who were planning on upgrading their cleanroom ventilation system. AirCraft Air Handling got to work with assisting in the design of a bespoke arrangement for this specific vertical AHU. It needed to function in an unclassified cleanroom, filtering dust and external pollutants out whilst controlling the humidity and temperature of the supply air. The clean room in question also required regulated air pressure for optimum performance. Our design team worked closely with the cleanroom contractor to finalise the [...]

Refurbishment Well-designed and manufactured Air Handling Units (AHUs) can have a potential life expectancy of around twenty years when correctly maintained. However, along the way, there are some items that may need replacement due to their usage, typically these could be coils, fans, gas heaters, thermal wheels, and recuperators. In some cases, an AHU will need a supply of hot or chilled water for thermal transfer with the incoming air. In areas of hard water, pipework and coils within the AHU are likely to experience limescale build-up, causing problems, potential damage and reducing their effectiveness. In most cases, all of the above can be dealt with under a refurbishment plan, AirCraft Air Handling have experience in working with our own legacy AHUs and units from other [...]
