A gas generator was recently installed for Jomarca, one of the biggest manufacturers of fasteners, bolts, nuts, and fixing elements in Brazil. The generator will supply exothermic gas to a continuous wire annealing furnace, which is part of the manufacturer’s efforts to meet market demand efficiently and sustainably for baling wire in the construction industry.

Using exothermic gas instead of nitrogen, the company expects to reduce operating costs, increase production efficiency, and improve the wear properties and finish of its wire products.

“By providing them with our latest generator technology," commented Marcio Boragini, sales director for Brazil at UPC-Marathon, "we have helped Jomarca improve process efficiency, achieve sustainability, and exceed their customers’ expectations for high-quality wire products.”

Jomarca already owns two endothermic gas generators from UPC-Marathon, a Nitrex company with headquarters in North America. In March of this year, the company upgraded its wire operations with a 150 m3/h capacity ExoFlex generator to ensure consistent gas composition and prevent scale formation on the wire surface.

Endothermic Gas Generator Added to Brazilian Fastener Heat Treatment System

A major fastener manufacturer in South America recently received delivery of an endothermic gas generator intended for heat treatment operations at the company’s Brazilian plant.

Jomarca, a Brazilian producer of fasteners for the furniture, tooling, construction, and do-it-yourself markets, purchased the Atmosphere Engineering™ EndoFlex™ generator from United Process Controls (UPC) in reaction to doubled carburizing operations and increased production capacity. Carburizing operations now include ten large continuous rotary retort furnaces that process over 2200 US tons (2,000,000 kg) of fasteners a month.

The high-capacity generator was integrated into the plant’s existing gas distribution system in the first quarter of 2018 and is supplying endothermic gas to all carburizing furnaces. The EndoFlex operates at a lower cost and mixes to more accurate ratios, aimed at maintaining a constant furnace atmosphere and a consistent gas quality at all times. The enhanced control capabilities of the EndoFlex allow for continuous control and monitoring of CH4, dew point, differential pressure, gas temperature, and retort burnout, as well as data logging, which is critical for troubleshooting and meeting regulatory requirements.
