High Pressure – a Green Future

There are so many industries that use high pressure. This could be through pumps, compressors or vacuum. And they all have one thing in common. They, like us, are part of the green future. The energy transition. The drive towards net zero. Without doubt, they/we have to be!

We can say truthfully that we want to be green, and perhaps it could be our mission. However, it’s what the customers want that really matters. And industry is increasingly demanding pumping equipment for renewable energy applications and equipment powered by renewable energy. If we are to thrive as a company, we must continue to adapt to our customers’ needs. In essence, we must build flow solutions that meet the ever-changing demands of industry.

As a result, much talk at Calder over the last few years, and even more recently, has been about two things. Firstly, how can our machines utilise green energy sources for their own power. And secondly, what high pressure pump, compressor and vacuum packages will support the emerging zero carbon industries. In both cases, it is our huge design and engineering experience, coupled with a smattering of entrepreneurship, that will ensure our company is part of the solution to our environmental issues.

A Sample of our Recent Electric Pump Unit Supply History

As it happens, we have been designing and manufacturing electric-powered units for many years. Increasingly, these units receive their power from renewable energy sources.

From the following projects, find out more about our design and build experience:
Thermal testing and pumping system for geothermal energy recovery.
Paint shop cleaning system for the automotive sector.
Formwork cleaning pump skid for a construction company.
HPHT and Base Oil Washdown skids for an Offshore Platform.
Test package for North Sea subsea pressure testing.
Tank cleaning pump skid for a chemical manufacturer.

High Pressure - Product Design for Green Energy

For some time, we have been developing our product range to meet the climate targets this world needs to achieve. Much thought has been given to our aim of making our pump units operationally zero emissions. Similarly, where do our products fit within the developing post-carbon industries? This is an evolution, not revolution, of product design that takes with it the tenets of quality and reliability on which our company’s success is based.

MultEjet - ATEX Zoned Electric Waterjetting Pump Unit

A recent development has been the MultEjet. This features the latest electric motor drive technology with integrated VSD. And, significantly, this is all housed in a single container certified to ISO 10855-1 suitable for use in ATEX Zoned areas. Previously, where a VSD was required, this would be housed in a separate offshore container. In addition to the extra costs, this took up valuable space on the offshore platform with the result that diesel-driven units were preferred. The MultEjet enables operators to choose an electric-driven unit with integral VSD at the right price (and size!).

Eco-friendly features of these units include:

  • Variable speed (10% – 100%) allowing greater range of flow adjustment than a traditional diesel engine unit.
  • More efficient (>90% efficiency) than the fixed speed/diesel unit (approx. 50% efficiency) due to optimisation of total current to motor.
  • Pump speed can be automatically adjusted to maintain a set flow or pressure. For example, to extend nozzle life.
  • Convertible to meet various pump performance requirements.

With offshore platform electrification gaining pace, this product is here at the right time, the right price, and with the right technology. This evolution is already forming the basis for the future of our onshore, environmentally friendly high pressure pump units. In addition to pump packages housed in offshore containers, we also design and manufacture many pump skid packages.

MultiJet – Mobile, Road-going, Waterjet Pumps

Operators need mobile waterjetting equipment that produces pressures up to 4,000 bar. Industry uses these units for concrete hydrodemolition, surface preparation, tube and tank cleaning and much more. Frequently, the work site is remote from a power supply and diesel engines are the only current, viable option. In the short term, all of our road-going units benefit from the incorporation of a Stage 5 engine. The Stage 5 power unit uses the very latest in ultra-low emissions technology.

We are now working on the next generation of these mobile waterjetting pumps. The two main renewables technologies we are looking at present very different challenges. The first requires few design modifications, but the infrastructure isn’t quite there yet. The other requires fundamental changes to our design to accommodate the technology. And whichever of the options we choose, we will need to future proof the design to align with the rapidly advancing technology.

Water Recycling and Filtration

The advantages of using high pressure water for cleaning and surface preparation are many. There are no chemicals or abrasives required – just water. Options are available to alter the pressure to suit different materials, and the process returns metals to their original surface profile. And let us not forget, high pressure water is fast and efficient.

But there is more! The waste water can be filtered and recycled. This is ideal where water is scarce or the supply suffers from frequent interruptions. In fact, even where there are no water supply issues, recycling water has to be the best option for our environment. The used water is collected and treated for re-use or for safe discharge back to its source.

Hydrogen, CCUS and Geothermal Energy

It was pleasing to see so much interest in our pump systems for hydrogen, CCUS and geothermal energy at the recent Offshore Europe exhibiton in Aberdeen and also at last year’s Offshore Northern Seas (ONS) exhibition in Stavanger. Looking ahead, it is clear that the energy transition will also be an important talking point at ONS 2024. The focus of ONS 2024 will be ‘IMAGINE – Can you IMAGINE the new energy future?’..
