A heat treat furnace manufacturer with North American locations will provide an American partner with two identical continuous CAB lines for brazing aluminum heat exchangers, specifically battery coolers. The furnaces will be used in Mexico and Spain.
The SECO CAB lines will be used for protective atmosphere brazing aluminum of heat exchangers. Such solutions are used by leading automotive parts manufacturers and are used for mass production of battery coolers among other types of heat exchangers. This purchase was preceded by tests in the R&D laboratory.

Vacuum heat treat operations expand for ZDT Glimag, an entity providing services in the field of vacuum heat treatment, laboratory tests, and production of parts for mining machines.
The addition of this Vector® vacuum furnace will be the third vacuum furnace from SECO/WARWICK. The current design has an operating space of 600 x 600 x 900 mm and will be equipped with numerous options to allow a wide range of heat treatment processes for various steel grades. Main processes will include vacuum brazing, FineCarb® vacuum carburizing, and high-pressure hardening. The design of the chamber size will enable efficient heat treatment of large packages of test and research elements.
The efficiency of processes is also influenced by the ability to cool at 15 bar (which, unlike the old furnaces, eliminates the need to wash the parts after the process). In combination with inverter control, the system also helps reduce power consumption peaks, which are so problematic today. Another big advantage is low heat losses and appropriate temperature uniformity in the heating chamber, which is resistant to rapid wear and is easy to use and service.

Beata Kowalewska, president of the Management Board – Financial Director of ZDT Glimag, comments: “Since the 1960s, we have been designing prototypes, conducting research and technological tests, and implementing new technologies for mining. We are currently in the process of materializing the project titled ‘Implementation of an innovative product resulting from research and development work: a brake pad with a composite friction layer with increased abrasion resistance,’ implemented under the European Funds for a Modern Economy (FENG) 2021-2027 Program. FENG is a program supporting entrepreneurs in the area of broadly understood innovation. It places great emphasis on R&D activities.”
He continues, “The new SECO/WARWICK furnace fits perfectly into the policy of broadly understood modernity implemented in this project. It will streamline and expand the scope of heat treatment processes and improve their economics, taking into account energy savings and the graphite chamber efficiency. It will also ensure the process cleanliness and velocity. With the FineCarb® vacuum carburizing option, the technology also increases our flexibility and research capabilities. Additionally, this technology will allow us to perform more difficult processes requiring extremely low contamination levels, thanks to the ability to obtain the appropriate vacuum needed for these processes.”

Maciej Korecki, VP of the Vacuum Furnace Segment in the SECO/WARWICK Group, comments on ZDT Glimag saying, “It is a center very well oriented in the metal heat treatment industry, constantly testing new, innovative solutions that in turn make the mining industry more efficient. The new Vector will introduce revolutionary changes in the hardening plant, introducing innovation and a very wide range of precise processes.”
The Vector® line vacuum furnaces can be used in most standard vacuum carburizing, hardening, tempering, annealing, supersaturation, and brazing processes. At the same time, the solution can be adapted to the recipient’s individual requirements, and therefore to a specific industry, an attribute necessary for research centers that test innovative solutions for external customers.
The solution‘s characteristic features are convection heating, i.e., a system improving the heat transfer efficiency when heating at lower temperatures, and directional cooling, which allows complex, flimsy, and long elements to be cooled in various ways, minimizing their deformations. An additional advantage is the vacuum carburizing option, which allows users to carry out precise processes to increase the steel surface hardness (carburizing) during the entire thermal process.

A Scandinavian manufacturer of heat exchangers has purchased two CAB lines, which will be delivered to factories in Mexico and Poland. They will be used for brazing heat exchangers for trucks and buses as well as power generators. The deliveries will be synchronized to arrive to the factories in the same timeframe.
The order is being carried out bySECO/WARWICKGroup’s Chinese branch. This partner has been operating globally since 2016, offering large-size heat exchangers for buses and trucks. The CAB lines on order meet the protective Nocolok® atmosphere aluminum brazing technology requirements.
Said Piotr Skarbiński, vice president of the Aluminum and CAB Products Segment at SECO/WARWICK, “This is a unique project for us, as we have sold two furnaces with the same delivery date to one customer at two different locations. It will be a logistical challenge overseen by SECO/WARWICK China.”

Skana Aluminum Company in Manitowoc, Wisconsin, has recently been supplied with an Exogas™ exothermic atmosphere generator.
The atmosphere generator from SECO/WARWICK USA, an American SECO/WARWICK Group subsidiary, provides an indirect-chilled exothermic atmosphere for annealing, brazing, normalizing, drawing, and tempering.
Says Marcus Lord, managing director of SECO/WARWICK USA, “At 30,000 CFH, it is one of the largest atmosphere generator units we’ve made to date. It should be plenty large enough to meet the exothermic atmosphere needs of the multiple processes within the Skana plant.”
Skana has also placed an order with the furnace supplier for a smaller atmospheric gas drier for use elsewhere in the plant.

Recently, Solar Atmospheres Eastern PA commissioned a new 25,000 square foot brazing facility aimed at high-volume, high-quality braze production. The facility features six vacuum furnaces dedicated to brazing, including an all-metal hot-zone furnace designed for brazing stainless steel to copper with silver and gold-based braze filler metal (BFM).
The heat treater specializes in the brazing of high-value components utilizing filler metals based on nickel, silver, gold, and copper. The new state-of-the-art production facility has 4,000 square feet of climate-controlled workspace, where technicians assemble and inspect parts, ranging from tiny capillary-tube manifolds to large land-based gas turbine blades. The operation incorporates increased capacity for helium leak testing and pre-braze tack welding of braze assemblies.
“With Nadcap accreditation and AS9100 registration, our new facility operates as one expects from the Solar brand,” states Chip Lahneman, general manager of Brazing at Solar. “The investment in our new facility demonstrates Solar’s commitment to meeting our customers brazing needs, now, and in the future.”

At the end of March, a vacuum aluminum brazing furnace was shipped to a manufacturer that serves the aerospace industry. The North America company produces complex heat exchangers, cold plates, and avionic enclosures.
The furnace, from PVT, Inc., has an AMS 2750 qualified work zone of 36” x 30” x 90” with type B instrumentation and Class 1 temperature uniformity. In addition to this furnace, PVT delivered two furnaces in Q4 and one furnace in Q3 2022 to companies manufacturing components for avionics, MRO (maintenance, repair, and overhaul), and electromechanical assemblies.
A Swiss commercial heat treater ordered a vacuum furnace. A system will increase the production capacity of their nickel and silver brazing processes.
Maciej Korecki Vice President of Business of the Vacuum Furnace Segment SECO/WARWICK
The SECO/WARWICK vacuum furnace helps with hardening larger size parts and significantly increases the efficiency of the current hardening plant. The furnace increases production. In the version ordered by the Swiss, a large working zone (36"X36"X48") with the potential to adjust to an oversized load utilizes the advantages of a round heating chamber.
“[With a] cooling capacity of 15 bar, it is possible to process parts that require very fast cooling . . . . Vector also allows the system to perform more difficult brazing processes with either nickel or silver," explains Maciej Korecki, vice president of the Vacuum Furnace Segment, at SECO/WARWICK Group. "This is our second installation with this partner. Previously, we delivered a solution from the SECO/WARWICK furnace family of a similar size, in a non-pressurized version."
