As experts in air technique studies, DEFISA designs and manufactures all types of industrial equipment intended for gas depuration and/or dust collection to match our costumers’ needs.
Turnkey projects: DEFISA takes charge of its installa-tions from their original conception through process optimization, equipment supply, transportation, dismantling, erection and commissioning.
Our reputation is based on over 40 years of both national and international experience and a long lasting customer base.
We also ensure an after-sales service both by training our customers’ employees for optimal equipment operation and by ensuring the availability of spares.
A breath of fresh air
Anti pollution equipment
Taking into consideration all the industrial anti pollution equip-ment available, the ESP is often the only solution. Overall, its mains features are: low energy consumption, long lasting mate-rials and a very easy maintenance.
Their basic industrial utility is the recovery of thick particles before they reach the bag filter or ESP.
Our wet filters are designed and manufactured to excel in wet scrubbing systems. Amongst its features we could highlight its high efficiency with soluble and/or humectable particles, its low working cost and, as a plus, the little space it requires to be erected due to its stack-shape design. Our scrubbers have been designed to be manufactured in a wide range of materials capable of facing every corrosion problem that may arise in industries.
Exchangers are made of a tubular beam through which hot dusted gases pass while a cold air flow is forced on the outside of the duct by means of axial fans. They are very effective (good exchange rate) and have a very low gas pres-sure drop. Exchangers come with a hopper for dust collection on its underside. The hopper is fitted with a screw conveyor for evacua-tion of the dust.
Venturi Reactor.
Lime slurry or water is used in gas conditioning towers.
Bag Filters are the most common and efficient equipment used in the collection of solid particles in air and/or gas depuration proces-ses.
These use the same kind of ducts as those used in exchangers but, instead, a centrifugal fan is used for cooling. The heat exchanger is fitted with an automatic and continuous duct cleaning system.
These are cleaning systems desig-ned to avoid polluted environ-ments that pneumatically trans-port the aspirated product into storage silos. Afterwards, by means of an appropriate evacua-tion system, the dust is evacuated into tankers, trucks or Big-Bags.
