Detailed engineering for an automation project often consists of specifying field components (instrumentation), interpreting the applicable rules, specifications and local circumstances, creating control and visualisation software, and carrying out tests on the delivered goods.
Our engineering team consists of hardware engineers, ATEX specialists, software engineers, TÜV certified safety engineers, process experts and simulation experts, and we have many examples and specifications, which we can use to carry out a perfect detailed engineering project.

Specifying field instrumentation and the associated installation material requires experience and specialist knowledge. A good design requires knowledge of the process, and working with customer-specific standards, applicable regulations, local circumstances and customer-specific requirements. In addition to field equipment, Powerspex often delivers the automation system, which enables us to harmonise these in an optimum manner.
We are brand-independent and can provide automation in different systems.
Example projects: NEM B.V. – specifying and purchasing field equipment and installation material for various projects; Paroseni, Romania supplying installation materials for a coal-fired power plant for Hitachi; Denizli, Turkey; Pego, Portugal; Mukaizna, Oman; etc.
Our software department is able to create brand-independent software and we have carried out several projects in various systems. Our strength is that we are able to fully test our software with the aid of simulation models. We also specialise in designing fail-safe controls, during which our TÜV certified engineers are responsible for the safety concept. The combination of process, simulation and programming knowledge results in a fast and effective design of the basic process by us.
Example project: NUON WaWa – the central unit in Utrecht carries out the central control of 11 substations, which have all been replaced by Powerspex.
We are familiar with the ATEX and IECEx rules. Powerspex is able to engineer and build explosion-proof systems in our ATEX certified workshop. Currently, these are intended for ATEX zone 2. We are in the process of certifying our system through DEKRA (NoBo) for zone 1 and also for IECEx. This means that, following certification, we are able to build systems for ATEX and IECEx zone 1 and 2, gas and dust.
At the moment, we develop systems that meet the requirements for explosion safety in accordance with: Ex e, Ex i, Ex nA, Ex p and Ex d.
We also employ specialised technicians holding an IECEx V certificate and having followed explosion-proof cable gland training, specialists who followed IECEx scope 3 and 6 training (specifically for installation) and IECEx scope 7 and 8 training (for the inspection of installations with regard to explosion protection).
Specifying instrumentation requires expertise and a lot of experience. Our experienced instrumentation engineers use the calculation program Conval and specification sheets, and base their work on many years of experience. We specify instrumentation for customers operating in various sectors, varying from the usual measurement systems, deductible measurement systems, wall material measurement systems, water analysis systems to emission measurement systems.
And due to our process knowledge, we are also able to specify valves, turbine bypass systems and safety systems. We are often able to provide better solutions because the choice of instrumentation is often linked to the software solutions.
Powerspex has developed its own simulation platform on which we are able to create any complex model, control, operation or visualisation. With our DCS compilers, we are able to copy DCS software and generate this in our platform. In addition to testing our own software, and setting out and checking the design, we create complete training simulators for power stations. These are practically 1-to-1 copies, with which scenarios, starts and stops can be made in fast and slow mode.
Example projects: Coal-fired Power Station Amer 9 for RWE – approx. 1700 screens and 4000 process objects; Claus Power Station for RWE – 246 screens and 6400 process objects; Moerdijk – 295 screens and 5000 process objects; NUON Hemweg 8 – 290 screens and 6000 process objects; NUON District Heating System Utrecht – 62 screens and 2000 process objects.
