APD's control systems can be found wherever reliable, intelligent control is needed.  The industry sectors we work in are diverse and our team enjoy the technical challenge of developing control solutions, perfectly attuned to the needs of our customers across multiple sectors.



Efficiency, quality assurance, innovation and cost-effectiveness are the key drivers within the automotive industry. Since these are our core values it is not surprising that the automotive industry is an important sector for APD. 

Automation has transformed the tardy reputation of the 1970s UK car industry to that of 'World Class Manufacturing' and APD has played its part in this transformation.

Being based in the country famous for its whisky, gin and other spirits it would be strange if we had not worked in this important  (and from a controls point of view), sometimes challenging environment. We are proud to say we have played our part  in the production of Scotland's best known export.

The work carried out on these sites is not always obvious to the casual onlooker, everyone can picture the copper Stills but the variety of systems on these sites goes much deeper and we've been doing it since the early 90's


  • Large scale steam production

  • Mash tun control & monitoring

  • Water treatment

  • Tank farm control

  • Bottling & packing lines

  • Energy monitoring

The specific work APD has carried out for the naval defence company cannot be discussed but we can say that since 2015 we are proud to have designed, built, programmed and tested some of the most complex controls every under-taken by our company.

Possibly the most challenging sector for any manufacturer to work in. Applicable standards, technology used, rigours it is subjected to, long timescales, quality control and not forgetting the strict security over some projects. All of these factors make working in this sector very specialised but it is another challenge successfully taken on by the company.

  • Deck handling equipment

  • Submarine controls (classified)

  • Training simulators for sub-mariners

Here at APD we understand that safety is the key factor associated with working on nuclear industry sites. Since winning our first project in 1999 at the Chapelcross nuclear station in southwest Scotland, we are extremely proud to say we have an unblemished reputation and perfect safety record 

What can initially appear as a simple project can quickly become a challenge in this sector where patience and extreme attention to detail are required for success. Some of our work in this area includes:

  • Fuel element discharge machines

  • Power and lighting distribution for asbestos removal on heat exchanger towers

  • Reactor pile cap heating

  • Asbestos handling facility

  • Control of 11Kv electrical sub-stations

Working in power stations goes hand in hand with safety. For 22 years and counting, APD has an unblemished safety record at the Chapelcross Power Station in southwest Scotland. 



If we hadn't thought about it before the events of 2020 have reinforced just how critical the pharmaceutical industry is to us all. The fundamental principles of Process & Batch control used in the other sectors mentioned are present here too, but refined to a level of precision and detail that is not required in many other industries. Whether it's measuring out ingredients or working through a defined recipe, the ability to track, log and verify every action is paramount for quality control and safety of the end product.

Below are some of the key bullet-points APD has implemented when working within this sector:

  • Batch control and recipe management

  • Compliance to FDA 21 CFR Part 11

  • Mission-critical dual redundancy on Servers & PLC's

  • OEE downtime analysis

  • Client server SCADA systems

  • Hazardous area computing

If there is a single sector that is guaranteed for growth in the coming years it is the Renewable and what we call 'Smart Energy' sector. We are not limiting ourselves to a single part of this, we are taking a holistic approach, ruling everything in and nothing out. Whether it is power generation, power storage, intelligent management, smart grid, hydrogen production or carbon capture we see a direct correlation between the systems we have built in the past and the systems we will build in the future.

As far back as 2012 when we designed the controls for a cutting edge Hydrogen Electrolyser we have continued to design and develop systems across a range of applications including:

  • Solar, wind power generation & storage

  • Intelligent energy management

  • Autonomous remote pumping

  • Ground-source and air-source heat pump control & monitoring

  • Peak shaving

  • Hydrogen generation
