Options & Upgrades

Airlock

Customizable airlock design is the section that separates the flushing area before entry to chamber. The airlock replaces the mine air with breathable air and makes sure that no contaminants enter the chamber. 

Pneumatic Air Curtain

The pneumatic air curtain prevents toxic gases from filling in by forming a curtain with the airflow at the entrance of the chamber or airlock section. The air curtain starts to operate as soon as the sealed door open and stops when it closed. It can also be controlled manually.

Life Support Extension

After the simultaneous disconnection of the mine air and the main power line connected to the refuge chamber, the standard 36-hour life support period can be extended to 96 hours by increasing the number of batteries, CO2 and CO damping chemical cartridges.

Digital Gas Measurement System

Works together with Aysan’s integrated gas damping system control panel, Digital Gas Measurement System measures the amount of CO2, CO and O2 gases in the environment and gives warning for concentrations that go out of safe ranges.

Voice Guidance System 

Works together with Aysan’s integrated gas damping system control panel, Voice Guidance System is a warning system that describes the procedure that should be followed in case of emergency. When used in conjunction with the digital gas measurement system, instructions for monitoring the gas concentration are also made by voice.

Positive Pressure Protection System

There must be positive pressure to prevent the ingress of gas from the outside into the refuge chamber and for the damping system to function. Mechanical systems that provide positive pressure in the shelter room are already present. With this option, positive pressure is maintained by spraying in when the pressure difference between the outdoor and indoor environment decreases.

Flood Protection System

The flood protection system, which is mounted in the mine air filter system, prevents the water to be filled into the chamber by the increase of high flow water or floodwater.

Emergency Mine Air Shutoff System

Emergency Mine Air Shutoff System works automatically if the mine compressed air line contains a dangerous gas concentration or if it reduces the internal pressure of the chamber.

Manuel Gas Measurement Kit 

The manual gas measurement kit consists of a metering pump and cartridges for the gases to be measured. The quantities of gases in the environment can be monitored manually by using this kit.
