The VentsimTM CONTROL (formerly SmartEXEC) software provides ventilation design capabilities which can be used for control and optimization.

After a programme of user feedback and evolution lasting almost a decade, VentSim CONTROL is today delivering outstanding results. In 2015, we developed a no programming 'plug and play' approach by incorporating instrumentation, automation, fans, dampers and fan motor starters that can be integrated quickly and easily into any Ventsim CONTROL system. Today, any type and size of Howden fan can be supplied in that 'plug and play' configuration.

From the surface, remotely monitor, control and automate real-time airflow and ventilation in your mine. Pre-programmed, easy to use. Easily expands for growing operations.

5 levels of control

1 - Manual

The operator uses the Ventsim CONTROL interface to remotely turn fans on or off, to modify their speed or to set the % on regulators. Settings stay as they are until manually changed.

2 – Automatic schedules and events

Ventsim CONTROL automatically changes underground fan and regulator settings as part of a schedule such as shift changes or planned events such as blasting.

3 – Automatic set points

The operator enters set points for airflow, gas levels, and/or temperature. Ventsim CONTROL reads real-time conditions from monitoring stations, then automatically adjusts underground fan and regulator settings to maintain set points.

4 – Dynamic requirements (VOD)

VentSim CONTROL uses dynamic tracking to determine requirements for airflow, gas levels, and temperature based on personnel and vehicles in each area. Ventsim CONTROL reads real-time conditions from monitoring stations and automatically adjusts underground fan and regulator settings to maintain safe and comfortable working conditions in a dynamic environment.

5 – Complete infrastructure optimization including main fans

Ventsim CONTROL reads real-time conditions from monitoring stations and automatically optimizes underground fan and regulator settings, and also adjusts main fan settings to maintain required levels and maximize energy savings. This level of optimization controls the ventilation system as a whole using advanced control strategies designed for mine ventilation applications.
