Role of effective ventilation

SUB’ROCA offers you ventilation solutions adapted to the specificities of your site, whether it is renovation work in confined spaces or excavation work in tunnels or underground mines. Axial axial axial fans are used for applications in main and auxiliary ventilation for mines and underground works in order to :

  • Renew the air in the environment so that it has a sufficient concentration of oxygen
  • Dilute VOCs, hazardous, noxious or explosive products in compliance with the VLEPs.
  • Evacuate the calories to obtain an acceptable temperature

The ventilation study carried out upstream enables us to define the appropriate equipment to achieve optimal energy consumption. It also defines the least restrictive ventilation network to be set up for your teams.

The term ventilation system is a device that either brings air into the excavation areas of the site or extracts the polluted air and then treats it. It is generally composed of: a fan, a duct network, a control and monitoring cabinet, a dust filter and a flow measurement device.

This system must be dimensioned beforehand to ensure that the installation complies throughout the life of the site. Our design office will dimension your ventilation system for you.

As a global player, SUB’ROCA designs a range of innovative equipment. Associated with our SHELT’AIR emergency shelters, the fans offer you a high level of productivity and safety, both in confined environments and underground spaces.

Smart & connected

The ventilation system controls airflow with unparalleled efficiency to provide adequate ventilation where and when you need it most. Reliable high-pressure fans and durable PVC-coated ducts contribute to optimal airflow day after day. Intelligent and efficient ventilation systems can reduce your energy costs by up to 50%. The ventilation system can be connected to the 4G network to allow real-time monitoring of the installation. Connectivity is possible on different access points such as WIFI, 4G or fibre, internet, MODBUS… on the different sites, our ventilation systems integrate a measurement box allowing: monitoring of parameters, real-time calculation of flow rates, etc. They can also be combined with other equipment.

Monitoring 

SUB’ROCA is committed to a process of permanent innovation in order to provide its customers with high quality and high performance solutions. Our engineers have developed cutting-edge innovative technologies such as monitoring and data acquisition systems to continuously monitor the state of the ventilation system. This real time data transmission solution can extend the efficiency and reliability of the equipment, the life span but also reduce the maintenance time of the fans and allow remote operation due to our digitalisation. Our monitoring and control system allows continuous analysis of the ventilation system parameters and advanced detection of anomalies, thus offering real added value.
