Arctic Vent Control

Reduce energy consumption
and optimize airflow
in underground mines

A ventilation on demand system that provides full control over airflow within the mining site.

This advanced mine ventilation system has vehicle detection, gas detection, air quality sensors and scheduling possibilities that optimizes the airflow underground.

The ventilation system works independently and does not require any infrastructure in the form of Wifi or other IT solutions. Because of its independency, Arctic Vent Control is easy to install and requires low initial costs. The system is also scalable, and each fan control unit is autonomous, that means the ventilation system can be installed and tested in one small part before continuing with installations throughout the mine.

More than 20 years in operation

Our ventilation on demand system was first installed in the LKAB mine in Malmberget Sweden in 1999. It has since then provided the 1250m underground mine with high quality air flow. The system has been continuously developed and improved to best fit the needs and requirements of the growing mine.

As the mine and its operations continue to grow and get more and more advanced, the ventilation system grows with it. As your mine changes, so does Arctic Vent Control. Because the ventilation system is modular, you can easily move control units to new mining areas.

Benefits of Arctic Vent Control

Save money – reduce costs

Because Arctic Vent Control will control the fans to only run when needed (using vehicle detection and other sensors) you will use less power and your fans will have a longer service life and less damage.

Safe work environment

Use of scheduled operation of the fans to flush out toxic gases after blasting etc.

Compatible with most fans and ventilation systems

If existing ventilation systems and fans are already installed in the mine, Arctic Vent Control will integrate via common bus protocols.

Low initial investment

Each fan control unit is autonomous, that makes Arctic Vent Control highly scalable. It can be tested in one area before full or progressive installation throughout the mine.

Autonomous operation

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.

Portable control units

As your mine changes, so does Arctic Vent Control. By being modular you can easily move control units to the new mining areas.

Quick and easy support ​

Since Arctic Vent Control can be controlled remotely from above ground, we can offer support, in most cases, without having to leave or home office. That means support becomes cheaper and faster and makes the downtime minimal.

Specifications and details

Gefa system-Arctic vent control-vod_vehicle_detectionVehicle detection helps control the airflow in underground mines and optimize the use of the ventilation system based on when there are vehicles in certain areas.

This will help with maintaining good air quality underground and at the same time reduce costs and emissions. 

A receiver is connected to the control system and a transmitter is installed in the vehicles. When a vehicle is detected, the fan starts according to a pre-set ventilation demand for that type of vehicle. That means a smaller vehicle will automatically trigger less airflow than a larger vechicle might. All depending on what is needed to maintain good air quality.

In some underground mines you have blasting at the same time every day. Arctic Vent Control will then schedule the control of the fan(s) to that exact time of day to help clear the air and maintain good air quality after blasting. This means that no manual control of the ventilation system is required for patterns within your workflow that reoccurs every day.

Controlling the air flow and being able to schedule the mine ventilation fans to your operation will help you keep good air quality in the mine and reduce costs.

Ventilation on demand optimized with pressure and air flow

It is easy to connect sensors for pressure, gases, flow and other metrics to Arctic Vent Control to enable further optimizations for extended Ventilation on Demand.vod_co control-ventilation on demand-arctic vent control-gefa system

We can also connect sensors for temperature, CO and NO (among many other types of sensors like dust, flow or pressure) to the control system underground. These sensors can inform the PLC how to adjust the fan(s) to maintain air quality.

Arctic Vent Control works independently and does not require any infrastructure in the form of Wifi or other IT solutions. That means lower intial investments and a more versatile system that can grow along with the mine.

Our demand controlled ventilation system comes with local human machine interface (HMI) installed nearby the fans underground to ensure access for operators or technicians. With the HMI attached underground you can see how and why certain fans operate, sensor data, alarms and do basic setups. The local HMI can be set up with authorization to avoid unauthorized access.

Customer reference

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.
