Instrumentation & Electrical (I&E) Services

What do we mean by I&E service? Quite simply, we refer to the routine maintenance of your instrumentation and electrical assets.

Process instrumentation provides one of two functions; it measures and provides feedback, or it controls another item. If it’s not working correctly it compromises the integrity of your plant.

Electrical infrastructure conveys electrical energy around your plant to provide motive power, ventilation, lighting and power for personnel at the point-of-use.

Like all items of infrastructure, I&E systems require regular maintenance.

Entec excels at servicing all types of process instrumentation, such as instruments to measure pressure, temperature, flow, levels, conductivity and mass, and instruments to provide control such as actuators and positioners. Entec also specialises in all aspects of gas detection systems – both portable and fixed-point installations – including its routine service and calibration.

Process instrumentation is found all over industrial and manufacturing sites; it allows a process to be measured and controlled and is integral to ensuring the quality, consistency and reliability of the process, and therefore the quality of the finished product.

Process instrumentation often provides critical control over product quality (e.g. in food and beverage processing) and the safety of a plant and the personnel working in it.

Similarly, electrical infrastructure is embedded throughout most industrial plants. It’s important that its functionality is periodically tested. It should be checked for signs of wear or fatigue. From the simple type of checks from visual inspections and “test-and-tagging” through to analytical procedures and thermographic imaging, routine maintenance is crucial to ensure the ongoing safety and reliability of your electrical systems.

Instrumentation & Electrical (I&E) services

Why is instrumentation & electrical servicing important?

Process instrumentation and electrical systems should not be “fitted and forgotten”. Instruments and electrical plant can be subject to physical damage or disturbance, environmental damage from exposure to the elements or changing air quality or may simply require periodic maintenance due to the nature of their design.

Instruments that are not correctly serviced can no longer be relied upon to provide reliable or repeatable measurements, or to provide accurate process control. Electrical plant can degrade with time or due to environmental damage. Also, as with most products that require periodic service, it is more cost-effective to provide frequent minor service rather than run it to failure and face a more expensive and disruptive replacement.

Failure to regularly carry out routine service on instrumentation and electrical systems raises the spectre of…

  • Degraded accuracy or performance of instruments, jeopardising the output of your plant’s process.
  • Accidents and injuries resulting from process failures or exposure to unsafe electrical systems.
  • Commercial and reputational risk to your organisation.
Instrumentation & Electrical (I&E) services

What should I look for in an instrumentation & electrical service provider?

The reliability and integrity of your process ultimately comes down to the quality of the plant, the quality of the people looking after the plant, and the processes that they follow. You need your plant to be serviced by people who are qualified and experienced, who are using the correct tools, and who are following the right processes and procedures.

Entec is a highly reputable and capable provider of instrumentation and electrical service. Our I&E service staff are either dual-trade I&E technicians, instrument technicians, or electrical technicians who are cross-training to dual-trade.

Entec’s staff are equipped with the correct analysers and calibrators in order to provide consistent and repeatable service and calibrations, and we are equipped to work on site and in our own workshops; whatever fits the need best.

The key to delivering excellent I&E service is to have a questioning mind. We don’t employ automatons who are only interested in getting the service finished and moving to the next job. If something’s not working, our techs want to discover why it’s not working. They are interested to look upstream and downstream in the process for clues or evidence. And then they’ll come and talk to you to share their findings, so that you can collaboratively work on a solution.

And crucially – Entec’s instrument technicians operate under the umbrella of Entec’s IANZ accreditation. This is a big deal in terms of the service we provide.

IANZ Accredited Calibration Laboratory

What does IANZ accreditation mean?

IANZ stands for International Accreditation New Zealand; it is New Zealand’s leading body providing accreditation services. The role of IANZ is to ensure the adherence to processes by its accredited organisations – an IANZ stamp is assurance that an organisation such as Entec has correct procedures in place, and that it passes regular compliance audits to show that it follows these procedures every time.

It boils down to this; an IANZ accreditation gives a customer confidence. Confidence that its service provider is following the correct processes, using appropriate equipment, and with the work conducted by suitably trained and competent people. An IANZ accreditation adds traceability to a calibration. What does that mean? It means that the key aspects of the calibration which is performed are recorded and can be traced back to New Zealand and international standards; while referencing who performed the calibration, what test equipment was used, and the results of the calibration. This adds an extra layer of assurance in terms of the quality of the client’s finished product.

Entec’s IANZ accreditation encompasses the following service activities for pressure, temperature, and electrical measurement classes of equipment…

  • Pipes, Hoses, Valves and Fittings: Pressure Range -98 kPa to 65900 kPa
  • Pressure and Vacuum Measurement: Pressure Range -98 kPa to 65900 kPa
  • Temperature Measuring Equipment: Temperature Range -35 degC to 550 degC or -270 degC to 1372 degC by electrical simulation
  • Temperature Controlled Enclosures: Temperature Range -35 degC to 200 degC
  • Calibrators for Instruments: DC volts, AC volts, DC current, Resistance, Frequency.
  • Indicating Instruments and Recording Instruments DC volts, AC volts, DC current, Resistance, Frequency.
  • Signal Sources: DC volts, AC volts, DC current, Resistance, Frequency.

This means that when Entec carries out a calibration of one of these types of equipment, it can provide an IANZ stamped calibration certificate as evidence of the work performed. To repeat, this gives the customer confidence of the quality of the work performed. In many cases – particularly in the food and beverage sector – using an IANZ accredited service provider is mandatory.

Mobile plant rooms

Mobile Plant Rooms

Entec provides a bespoke design and build service for mobile plant rooms. By “plant room”, we are referring to an enclosed space that houses a variety of plant, ranging from LV or HV electrical infrastructure, to generators, pumps, boilers or HVAC equipment.

So, why mobile? Especially if the plant installation is going to be permanent?

Entec has completed installation projects for 35 years, involving large generator packages, switchboards and control panels and all manner of ancillary plant. We have learnt through experience that the efficiency and quality of installation work is greatly increased within a workshop environment. Site travel is reduced, site safety risks are minimised, and a manufacturing workshop is typically a cleaner, quieter and more comfortable environment than a construction site – conducive to skilled tradesmen delivering their best output in the most efficient manner.

A mobile plant room can be factory-acceptance tested at Entec’s workshop. Following transportation to its destination, the on-site installation is a simple process and the plant is ready for commissioning.

Mobile Plant Rooms Mobile Plant Rooms

Future mobility

A further advantage of the mobile plant room is that it can be readily relocated in the future. This is particularly applicable in operations such as mines, quarries and landfills, where site infrastructure is regularly reconfigured to adapt to site requirements. Mobile plant rooms are also ideal for short-term installations, such as construction projects or special events.

Enclosure styles and sizes

Mobile plant rooms can be built to any size, provided they meet the constraints of road transport regulations. Entec’s experience includes an ISO 10 foot container at the small end (3.0m long x 2.4m wide x 2.4m high), and a double ISO 40 foot container at the upper end (12.0m long x 4.8m wide x 2.6m high).

ISO shipping containers are ideal due to their standard sizing, ease of lifting, and the cost effectiveness of international freight via container ships (subject to fitting the ISO envelope). Entec has installed additional roof assemblies onto containers to prevent accumulation of rain or dirt.

Entec can also offer mobile plant rooms using self-frame enclosures. These are available in any size, again subject to transport restrictions. The self-frame enclosure has a pitched roof and a high stud, providing more flexibility to house larger items of plant.

Project Examples

Entec has manufactured mobile plant rooms for numerous applications including…

  • HV generator switchgear
  • Power factor correction
  • Variable pump speed drives
  • Generator and network supply connection
