Dena stands out for the design, construction, and installation of suction and fume treatment systems, meeting the needs of various industrial sectors, from small to large-scale operations.
To ensure effective particulate control, we offer a wide range of technologies, selected based on the type of gas to be treated and the emission limits required by current regulations.
The main components of our systems are entirely manufactured in Dena’s workshops. Thanks to in-house design of filtration units—such as bag filters, cartridge filters, coalescing filters, electrostatic filters, cyclones, and scrubbers—our clients benefit from customized solutions developed to meet their specific needs.
Our extensive experience in production processes and a deep understanding of customer requirements enable us to optimally configure any suction system, delivering tailor-made solutions for various industrial sectors, including:
Energy sector: Fume treatment systems for incineration and waste-to-energy plants, biomass industrial boilers, and gasification plants.
Steel and metalworking sector: Suction and fume treatment systems for die-casting, core-making, and smelting furnaces.
Recycling sector: Systems for the treatment and separation of urban and industrial waste, including dry suction systems to reduce dust generated by shredding, handling, and compacting. We also design wet filtration systems for treating and handling organic waste, as well as other processes.
Chemical, pharmaceutical, and food industries: Suction and fume treatment systems for ovens or steam generators, and heat recovery systems for sugar production facilities.
Thanks to our technical expertise and innovative capabilities, Dena provides systems, including fully customized ones, that ensure efficiency, safety, and environmental compliance, adapting to the challenges of an ever-evolving market.
