Heavy-duty corrosion-resistant axial flow fans for forced-draft cooling, process air supply, and ventilation in oil refineries, petrochemical complexes, and chemical processing plants with flameproof motor options.
Axial Flow Fan for Petrochemical Plant & Refinery — Manufacturer & Supplier
Vayuvents Pvt. Ltd. manufactures and supplies axial flow fans for oil refineries, petrochemical plants, and chemical processing facilities — from process air-cooled heat exchangers and cooling towers to substation ventilation and plant building air handling.
Petrochemical and refinery environments impose the most demanding requirements on fans and blowers — high ambient temperatures, corrosive process fluids, hydrocarbon vapours, and hazardous area classifications combine to create conditions that standard fans cannot survive.
Vayuvents supplies axial fans built for petrochemical service — spark-resistant aluminium or SS impellers, anti-corrosion epoxy or SS casing, and motors with flameproof (Ex-d) or ATEX certifications suitable for Zone 1 and Zone 2 hazardous area classification as per IS 5572 and IEC 60079.
We have supplied to clients in JNPT petrochemical belt, Gujarat refinery clusters, and export projects in Jubail, Yanbu, and UAE with complete material documentation and EPC contractor specification compliance.
How It Works in This Application
Process Heat Source
Crude oil distillation columns, reactors, and heat exchangers generate significant thermal loads that must be dissipated through air-cooled heat exchangers or cooling towers.
Forced Air Over ACHE Tubes
Axial fans mounted above or below ACHE fin-tube bundles force ambient air across the hot tube surfaces, carrying away process heat.
Ventilation of Process Buildings
Axial fans provide fresh air ventilation and hazardous vapour dilution in pump houses, compressor buildings, and electrical substations within the plant.
Exhaust of Flammable Vapours
In hazardous classified areas, flameproof axial fans create continuous dilution ventilation that keeps hydrocarbon vapour concentrations below the Lower Explosive Limit at all times.
Recommended Variants
Flameproof Motor Axial Fan
Ex-d flameproof motor with spark-resistant aluminium impeller for Zone 1 and Zone 2 hazardous areas.
FRP Blade Axial Fan
FRP blades and GI or FRP casing for corrosive process environments and coastal petrochemical sites.
Air-Cooled Heat Exchanger Fan
Large-diameter axial fans for forced-draft or induced-draft ACHE service with adjustable pitch for energy optimisation.
ATEX Certified Axial Fan
Full ATEX certification for international EPC projects requiring IECEx or ATEX Zone 1/2 compliance.
