"After installation of Artic Vent Control there was a 29% decrease in energy consumption
from the fans and a 40% decrease in energy for heating the mine air. The introduction of
this new system in the Malmberget mine have led to a decrease in the annual electric
energy consumption from 167 GWh to 72 GWh."
Fans only runs when needed by using vehicle detection and air quality sensors.
Use of scheduled operation to flush out toxic gases after blasting etc.
If existing systems already deployed Arctic Vent Control can integrate via common bus protocols.
As each fan control unit is autonomous Arctic Vent Control is highly scaleble and can therefore be tested in one area before full or progressive deployment througout the mine.
Each fan control unit can operate on its own if communication does not exist or fails. Arctic Vent Control can be controlled via local HMI underground and/or remote from above ground.
As your mine changes, so does Arctic Vent Control. By being modular you can easily move control units to the new mining areas.
A receiver is connected to the control system and a transmitter is installed in vehicle. When a vehicle is detected the fan starts according to a pre-set ventilation demand for the type of vehicle. To the control system underground can connect sensors for temperature, CO and NO (among many other types of sensors like dust, flow or pressure). These sensors can inform the PLC how to adjust the fan(s) to maintain air quality.
Arctic Vent Control will schedule the control of the fan(s) if you for example have blasting at the same time each day.
It is easy to connect pressure, gases, flow and many more sensors to Arctic Vent Control to enable further optimizations for Ventilation on Demand.
Our customers have reported that having a local HMI underground nearby fans has been very helpful. One can see how and why fans operate, sensor data, alarms and do basic setup. The HMI can be set up with authorization to prohibit unautorized access if need be.
