The construction of new shelters and the renovation of existing ones is an urgent need in modern Ukraine. One of the key elements in the design of a shelter is a functional and efficient filter-ventilation system. It is precisely this type of equipment that the Ukrainian company “Selton” develops and manufactures. Modern filter-ventilation units for bomb shelters comply with DBN and other applicable standards.
Why ventilation in shelters is a matter of life and death
Most often, existing shelters use Soviet-era air-raid shelters. They were built according to standards that have since become partially obsolete. The main problems with this type of equipment include:
- reduced protective capacity. Soviet air-raid shelters were designed with the potential threats of that era in mind. They are unable to purify the air of modern toxic, chemical, and biological contaminants;
- physical wear and tear. All equipment has a limited service life. Gradually, systems or their individual components fail and require replacement;
- the use of carbon-based absorption filters. Such elements lose their adsorption capacity under the influence of moisture and other factors;
- bulkiness and heavy weight. These are due to outdated technical and design solutions;
- significant energy consumption. As in the previous case, this is due to outdated technologies and the need for a stable power supply;
- inability to ensure complete airtightness, especially given the need for regular maintenance of the filter-ventilation system;
- lack of automation components. Manual or semi-manual switching of modes, monitoring of filter status, and other processes reduces the reliability of the filter-ventilation equipment;
- manual fan drive instead of a backup power supply system.
Given all of the above, it becomes clear that replacing the FVA with a modern system is a prerequisite for the full-scale operation of a civil defense facility.
Advantages of Selton CFS Systems
If you need to upgrade the ventilation system in your shelter, we recommend contacting a Ukrainian manufacturer. Our company, “Selton,” develops comprehensive solutions for shelters of various capacities. Our filter-ventilation systems comply with current standards and meet modern requirements. They are capable of operating in both ventilation and filter-ventilation modes. Moreover, the switch occurs automatically (when air parameters change) in a matter of seconds. At the same time, dust (including radioactive dust), chemical and highly toxic substances, and biological aerosols are removed from the airflow supplied to the breathing zone. Other advantages of the manufacturer’s FVU include:
- the ability to create positive pressure (overpressure). This prevents contaminated outside air from entering the room;
- high performance and energy efficiency;
- the ability to be powered by an AC mains supply or an alternative source—such as a battery, generator, etc.;
- a self-diagnostic system and automated control. This allows for the timely replacement of consumables and filters without worrying about the need to change the operating mode of the filter-ventilation unit;
- low noise level during operation;
- quick availability of replacement filters.
Step-by-Step Guide to Modernization
For professionals, the process of renovating a bomb shelter or civil defense shelter does not pose any particular difficulties. To ensure that a modern civil defense ventilation system functions properly, it is necessary to:
- examine and analyze the condition of the existing system and utility networks. Draw up a plan for the restoration work;
- dismantle the old equipment. In doing so, special attention must be paid to safety issues;
- carry out work to improve the utility networks, bringing them into compliance with current building codes and regulations;
- install and connect the selected filter-ventilation unit. Ensure its reliable and uninterrupted operation.
Renovating radiation shelters and bunkers is a complex, multi-stage process. Selton’s specialists will assist you in selecting and installing reliable and functional filter-ventilation equipment. To ensure your decisions are sound, consult the professionals.
