The Minac range from EFD Induction comprises compact and mobile induction heating systems with output powers of 10kW-220kW.

The small footprint, ease-of-use and manoeuvrability of a Minac induction heating system make it ideal for shipyard environments. A Minac is flexible, too: it is capable of performing heating tasks as diverse as brazing, pre and post-heating, shrink fitting and removing, tube bending, paint stripping and removing, and hardening coatings. A single Minac converter can typically support a virtually unlimited range of custom-built coils.

Many Minac models come in twin versions offering two independent power outputs (in effect doubling the productivity of a single system). The twin versions feature split-control panel displays from which each output can be set up and controlled. Minacs can also be used together with separate heating stations. This lets the Minac support large, flexible coils that can be shaped on-site to fit curved or irregular-shaped work pieces. Deck and bulkhead-straightening induction

EFD Induction pioneered the use of induction for deck and bulkhead straightening, selling its first Terac straightening system in 1981. Since then, Terac has evolved to remain the world’s premier induction straightening solution, with the latest model, the Terac 25, featuring a state-of-the-art generator with an output power of 25kW/40kW. Clean, fast, safe and easy to use — an operator using a Terac to straighten a deck. A complete Terac deck and bulkhead-straightening induction system and its small, secure container. It takes only a few hours for an operator to master the EFD Induction Terac deck and bulkhead-straightening induction system. Many Minac compact and mobile induction heating systems are compact enough to be transported by car. Minac compact and mobile induction heating systems' handheld transformers (HHTs) make it easy for operators to reach work pieces.

EFD Induction Teracs can be found at shipyards around the world. Customers usually cite a dramatic reduction in straightening costs as the biggest benefit of switching to Terac. This is because the Terac ensures: Rapid, repeatable, controllable and localised heat: Terac has been documented to cut straightening times by as much as 80% compared to flame heating and other traditional methods Straightening of convex and concave bulges: an operator can straighten both positive and negative bulges using the same simple-to-follow procedures Failsafe operation; it is impossible to overheat magnetic steel Small equipment footprint: a complete ready-to-work Terac system fits in one small storage container Maximum flexibility: a Terac works just as well on bulkheads as it does on decks Wide working range; an operator has a working radius of up to 60m (197ft) from the heat generator Maximum operator efficiency; a new operator can master the efficient use of a Terac system in only a few hours Turnkey induction bulkhead-straightening systems

The EFD Induction Terac is a complete, turnkey induction bulkhead-straightening system. The product, which fits in a small container for easy movement to and around shipyards, consists of: Heat generator Cooler Heating unit (also known as inductor unit) Operator panel Cables Optional system for handheld vertical operation Handheld bulkhead straightening

The deck-heating unit — which weighs only 10kg (22lbs) — is a mobile wheel-mounted coil and transformer. Magnets on the underside of the unit ensure accurate positioning during the heating operation. For bulkhead straightening, an optional handheld unit can be used either freehand or suspended by a suitable balancer.

Ergonomic design and light weight aren’t the only ways Terac protects operators’ health and safety. With Terac, no toxic gases are developed from the heating source, there is no acoustic noise, and there is less smoke than flame heating when working on painted or primed metal. Also, since operators need only heat one side of the plates, there is a lower risk of injuries caused by reaching and working under decks and in confined spaces.

The transistorised induction heating revolution was born to address the needs of one specific application: deckstraightening in the shipyards of Norway.

EFD Induction, Europe's largest induction heating company, has won an order for an automatic induction hardening and quenching system from NSK of Japan, the bearing and precision parts manufacturer. The system, which is to be used for hardening automotive components, is due for delivery before the end of this year.

Mitsubishi Heavy Industries (MHI), one of the world's largest builders of cruise ships and gas tankers, has installed two EFD Induction 'Terac 25' deck straightening systems at its main shipyard in Nagasaki, Japan.

Bjørn Eldar Petersen, a Norwegian executive with 20-plus years' experience in the global automotive industry, has been appointed CEO of the EFD Induction Group. Petersen takes over from Eivin Jørgensen, who, as planned, has stepped down on his 60th birthday.

EFD Induction, with Sweden's Royal Institute of Technology and leading research institute Swerea IVF, has launched a 832-page book entitled 'Steel and its Heat Treatment - a Handbook'.

Hugo Miebach, the global market leader in coil joining welding technology, has ordered EFD Induction equipment to integrate into three types of its laser welding systems. The EFD Induction equipment comprises Sinac induction heaters to pre-heat and anneal the weld zones. "Welding coils

ESAB, the world-renowned welding and cutting specialist, has ordered an EFD Induction Minac 50/80 Twin for one of its ESAB IT-100 automatic T-beam welding machines. The machine, to be installed at a shipyard in the Ukraine, is a fully automated solution with a welding speed of more than 1m/min. T

EFD Induction has developed an innovative door straightening solution for Libra-Plast, one of the world's leading manufacturers of bulkhead doors, hatches and containers for the maritime industry. The solution is based on EFD Induction's well-known Terac deck and bulkhead induction straightening

Every service call is unique. However, recently we received one that was truly extraordinary. Tom Smith, machinist for the 1925 steamship 'Saltsjön', rang and asked if we could help restore the old vessel by heating rivets for new, below-deck flooring. It sounded interesting, so we pa

EFD Induction recently delivered one of its new generation Terac 25 induction straightening systems to Keppel AmFELS in Brownsville, Texas. The delivery makes Keppel AmFELS the first purchaser in the Americas of the new Terac 25 system. Keppel AmFELS will use the EFD Induction Terac to

Most landlubbers don't know it, but the straightening of welded deck and bulkhead plates is a crucial task in modern shipbuilding. It's also a task that EFD Induction has been making easier and more cost-efficient for the past quarter of a century. In 1981, EFD Induction delivered its
