 Press Releases

  • Industrial induction heating expert EFD Induction and inductive charging and power supply innovator IPT Technology now form ENRX. The new company is represented in more than 80 countries and holds over 1,200 patents for induction technology. By bringing out the best of induction technology, ENRX is determined to speed up the journey to a cleaner and greener manufacturing and mobility.

    Ready to change the game

    The manufacturing industry is shifting toward eco-friendly and more efficient industrial heating systems. As induction heating is accurate, controllable, fast and repeatable, the technology is perfectly suited for smart factories driven by an Industry 4.0 approach. Industrial induction heating also promotes safe and healthy workplaces, and the technology has been proven for decades.

    “We are a new company with more than 70 years of experience in induction heating,” says Bjørn Eldar Petersen, CEO of ENRX. “Last year was record-breaking for EFD Induction. We passed our forecasted order intake for the full year in October. We now have a new brand, ENRX, and many products in the pipeline. The future looks bright for us.”

    Mobility is the other focus area for ENRX, and IPT Technology has been a pioneer in this field.

    The world of mobility is going wireless, and ENRX pushes the evolution further by removing the need for cables. Inductive charging of buses, cars, ferries and trucks is convenient for users and requires virtually no maintenance. The same technology can be used in factories and warehouses to charge mobile equipment, robots and vehicles. Another offer from ENRX is contactless power supply, where power is transferred instantly to tracks used for everything from conveyor belts to amusement rides.

    “Inductive wireless charging and contactless power supply are technologies for the future,” says Magnus Vold, CCO of ENRX. “In the new world that is emerging, everything is based on automation, digitalisation and electrification. With our portfolio of inductive charging and power supply systems, the only limit to what can be done is imagination.”

    Speeding up the journey

    ENRX aims to speed up the journey to a sustainable world through smart energy transfer. By offering technology for inductive heating, charging, and power supply with low or no carbon footprint, ENRX provides value to companies worldwide in manufacturing and mobility. The vision for the company is: “When people look back, they will find that we were years ahead.”

    “We believe that the right energy can take you anywhere,” says Inggard Torvik, CTO of ENRX. “Both in terms of what we do for our customers and how we interact with them. We know that change is always likely to meet some resistance, but there is simply no turning back within manufacturing and mobility. Instead, companies and organizations that act now are likely to be much stronger in the near future. We are ready when they are.”

    ENRX formally launches on the 27th of March, 2023. The company has a turnover of 135 MEUR and 1,100 employees, and the headquarters are situated in Skien, Norway. 


  • Since its introduction in May of last year, ENRX’s new Compact Weldac high-frequency induction welder has made a huge impact in the tube and pipe industry. But, to what exactly does this welder owe its success?

    The Compact Weldac hit the market like a storm in 2021. Despite the coronavirus-induced recession and low activity in global production, tube & pipe manufacturers lined up to buy.

    “In fact, making them in batches of ten at a time is not enough to keep up with demand,” smiles Sales Manager Mark Prasek at ENRX USA, offering up his explanation of why this small Weldac has become so popular.

    “To understand why the Compact Weldac took off like it did, we first need to understand the welder market”, he begins. “ENRX has long been a market leader in terms of technology, but better technology typically comes at a higher price. With larger welders, the high price of better technology can be more easily justified since they are used for larger product sizes on larger production lines that have very high downtime costs. In that case, technological advantages which benefit uptime, performance, and energy savings become more important than equipment cost. It is the total cost of ownership that is paramount. On smaller welders running on smaller production lines, the technological advantages are more difficult to quantify.”

    There are many low-cost welders on the market, so what ENRX aimed for was a welder that offered all the technological advantages they are known for, at a price point that could hold its own against low-cost competitors.

    The solution came from using existing proven technologies coupled with advancements in silicon carbide (SiC) inverter technology and then packaging it into a new, more compact frame. A design that focuses on welders rated for 300 kW and below, as well as a design that can be used on the largest market segment of tube mills in the world.

    “To be clear”, Mark points out, "the Compact Weldac is not a stripped-down or compromised design. It offers all the same benefits as its bigger brothers.”

    Such benefits include a short-circuit-proof design that protects the generator from arcs, flashovers, and direct shorts, resulting in higher uptime. The fully automatic electronic load matching means that no operator intervention is required. And, power regulation at inverter frequency is orders of magnitude faster than silicon-controlled rectifier (SCR) machines, so arcs and flashovers no longer need to be defects.

    The Compact Weldac is industry-leading as far as electrical efficiency goes, with 91% from the mains to the coil. Along with a constant high electrical power factor – 95% at all power levels –, there are substantial energy cost savings to be had.

    “The small footprint of the single-cabinet design not only makes the welder easy to install and retrofit, but it also requires less material to manufacture, so the lower consumption of both energy and resources makes the Compact Weldac a sustainable choice as well”, Mark says. “And last but not least, the advanced SiC inverter technology is covered by a 5-year warranty, which gives customers peace of mind.”

    “So, the answer to the question of success is really very good foresight by all the various teams at ENRX”, he concludes. “Management, R&D, Engineering, Production, and Sales all worked together to give the market what it wants.”

    Indeed, as a Sales Manager in North America, Mark has seen first-hand how the market has welcomed the Compact Weldac. Apparently, the first question many ask is: “Does it have automatic matching?”

    “Unless you have experienced a poor matching situation, it’s difficult to explain the advantages of automatic load matching”, Mark says. “Some producers just learn to accept that their welder won’t deliver full power across the product mix. However, the Compact Weldac not only offers automatic load matching. As with all ENRX Weldacs, it runs continuous automatic electronic load matching, which is done without operator intervention or any internal moving parts. Customers tend to relax once they hear this.”

    “The next surprise comes when looking at the installation requirements,” he continues. “The Compact Weldac is a single-cabinet machine, and that greatly simplifies installation, particularly in retrofit situations. Now, add a 5-year inverter module warranty and it becomes very clear this is not just like every other welder on the market. There are features with benefits at every point in the discussion”, he enthuses, brimming over with stories about how well the Compact Weldac has performed for customers.

    “Recently, we won an order from a US tube producer who said: ‘With everything you’ve shown me, I don’t know why I wouldn’t buy an ENRX welder.’ I agreed, and they purchased three machines”, he smiles.

    Another producer was experiencing increasing downtime from their existing welder. It was costing them considerable lost production at a time when they were already backlogged. Then they purchased a Compact Weldac. A month later, they came back for two more.

    “A third producer was experiencing poor matching capability and increased downtime on their welder”, Mark recalls. “The Compact Weldac fit nicely on their existing positioning table. They actually started making tubes on the second day of commissioning and were using less power to weld the same tubes!”

    “If ever there was a time to replace a vacuum tube or older solid-state welder, that time is now”, Mark Prasek believes. “The Compact Weldac will provide significantly reduced running costs combined with improved output power, raised efficiency, environmental benefits, and better profit. Need I say more?”



  • Compact Weldac 04 HFI Tube Welder
    Sometimes, big things come in small packages, or, as in the case of the new Compact Weldac 04, in a small cabinet. Less than 52 inches tall, this high-output solid-state welder uses minimal space while yielding a lot of power....

  • The new Compact Weldac 04, with an output power of up to 300 kW, boasts high-efficiency SiC inverters and a dramatically reduced volume. At only half the size of its predecessor, this welder has a minimal footprint but has lost none of the Weldacs’ well-known power and high efficiency. On the contrary, from the mains to the welding coil the efficiency is an impressive 91%.

    The convenient size of the Compact Weldac 04 saves valuable floor space. Measuring less than 1300 mm in height, 1500 mm in length, and 500 mm in width, it is very easy to install or retrofit in a production line.

    All ENRX Weldacs have a 5-year warranty on inverter modules and driver cards and are supported by our global network of factories, service workshops, and offices.

    ENRX leads the technological development of induction tube and pipe welding and provides equipment with the best power-to-volume ratio. We were the world’s first to offer 1100 kW in a single cabinet solution and are now proud to present the most compact one-cabinet welder on the market.
