Oxygen and Air Control Systems

In shelters designed for operation in complete isolation from external environment (lock up mode) for longer periods of time air regeneration systems must be installed to maintain the safe levels of Carbon Dioxide (CO2) and Oxygen(O2), as well as keep the overpressure (positive pressure) inside the shelter (pressurized shelter) which prevents from contaminated air entering the shelter.

Oxygen / Air Regulation Solutions

An oxygen / air regulation systems allow correctly maintaining the oxygen levels in the shelter or a sealed chamber and keep the overpressure levels.

Such systems are commonly based on release of oxygen stored in special oxygen tanks. The release of the oxygen can be controlled manually by valve or equipped with sensors and automatic mechanism that continuously measures the internal oxygen level and disperses metered amounts of oxygen from a compressed oxygen cylinder, to maintain safe oxygen levels for breathing.

Overpressure Gauges / Meters

Overpressure gauge / meter is a devise used to measure and monitor the differential pressure between shelter compartments (shelter main chamber, airlock, etc.) or between the protected area and outside. Overpressure is a critical part of the protection layers in the shelter and it is vital to constantly monitoring its values.
