New technical representation line
Underground
ventilation, with
local support.
Official Zitrón distributors in Argentina: 60 years building ventilation for underground mining, with projects in more than 80 countries.
Spanish technology, Argentine support.
Cuatro Fincas S.A. does business as Green Bulk. We supply industrial equipment and technical solutions for mining, oil & gas, infrastructure and agribusiness.
We work with top-tier manufacturers and provide technical support here, adapted to the way operations run in Argentina. With Zitrón, a world leader in underground mining ventilation, we add a new line to our portfolio, alongside Jain Irrigation.
What we solve in underground mining
Primary and secondary ventilation
Axial fans and jet fans for the main circuit and the development headings.
Ventilation on demand (VOD)
Variable frequency drives and automatic control to move the air the mine needs at every moment.
Silencers, ducting and accessories
To cut noise and deliver airflow to the face with the lowest possible loss.
Water and fluid handling
Pumping and water conveyance underground, quoted within the same project.
Zitrón product line
Every unit is designed for the tunnel, mine or site where it will operate.
Road and rail tunnels
Longitudinal and emergency ventilation for roads, metro and rail.
Mine ventilation
Primary and secondary circuits, underground, on surface and at the plant.
Jet fans
Jet fans for large cross-section tunnels.
Axial fans
High flow and pressure for long, large-diameter ducts.
Temporary ventilation
