AFT INDUSTRIAL

AFT INDUSTRIAL

AFT Sp. z o. o. is a manufacturer of round and louver damper valves, special fittings and distribution valves for many industrial applications. Mainly for the following systems: flue gas desulphurisation, NOx emission reduction, thermal waste disposal, biomass combustion, bag filters and electrostatic precipitators.

We offer design and manufacture of the above-mentioned products adapted to shut off and/or regulate the flow of flue gas, hot/cold air. In addition, we adapt our products to special parameters — high temperatures and aggressive media.

We supplement our offer in the field of production with consulting at the design stage. We provide supervision over assembly, commissioning and further service care.

Drive: with emergency < 5s opening/closing function

T (Tandem) and DB (double blades) dampers with welded construction are used for
100% tight shut-off of the medium.
For proper operation, they require the use of special sealing air system,  which are also included in our offer.

Double blade damper with sealing air system

SKID modules

SKID modules

Function: depends on customer requirements and system purpose.

In cooperation with our clients design office, we are also able to make modular systems — SKID. Due to wide design and implementation possibilities, we provide advanced systems designed for specific functionality. Our systems meet the requirements of various industry sectors and the destination process.

SKID systems that we also design and manufacture are sealing air systems used to create a barrier in Tandem (T) and Double Blade (DB) damper valves.

Układ doszczelniający

Układ doszczelniający

Funkcja: Przygotowanie powietrza doszczelniającego dla klap tandemowych i podwójno-tarczowych
Opcje: z nagrzewnicami elektrycznymi
z wymiennikami ciepła (parowymi)
z wentylatorami bocznokanałowymi
z wentylatorami odśrodkowymi
z kompleksowymi układami sterowania i zasilania
z dodatkowymi czujnikami i/lub osprzętem pomiarowym

Układ powietrza doszczelniającego został zaprojektowany do pełnienia funkcji wtłaczania powietrza wewnątrz tarcz klap tandemowych w celu zapewnienia 100% szczelności. Całkowitą szczelność bariery powietrznej uzyskuje się dzięki wtłaczaniu powietrza, między tarcze klapy, o odpowiednim nadciśnieniu w stosunku do ciśnienia panującego w rurociągu. SKIDy powietrza zajmują się odpowiednim przygotowaniem medium doszczelniającego.
