Anti-radiation shelter ARCA NOVA 3.2 for 27 people

Description

The ARCA NOVA shelter by BUNKEROK represents the strongest flagship next-generation modular protection shelters built to the modern CPS (Civil Protection Standard), designed for a new reality where security is not a temporary workaround, but a strategic responsibility for human lives.

The ARCA NOVA shelter is an essential solution for enterprises, educational institutions, and public organizations where legislation mandates certified protective shelters. It features a monolithic reinforced concrete structure: walls, floor, and ceiling are seamlessly integrated into a single reinforcement cage without joints or structural weak points. Installed in just one day.

Fully compliant with DSTU 9329:2025, DSTU B V.2.6-2:2009, DSTU 9195:2022, and DBN V. 2.2-5:2023 standards. Certified by the State Research Institute of Building Constructions (CAB "CENTROSEPROBUD").

Successfully passed proving ground tests in accordance with DSTU 9329:2025 (Annex A) requirements. To verify the maximum level of protection, ARCA NOVA shelters underwent additional detonation testing using a high-explosive fragmentation incendiary warhead (HEFIW-50) from a Shahed-136 type strike UAV (total mass nearly 50 kg) at a distance of 5 m from the structure—significantly exceeding official state standards (2 kg of explosive charge at a distance of 4 m). Following the tests, the shelter by BUNKEROK confirmed its ability to withstand a blast wave overpressure of 1300+ kPa instead of the required 100 kPa, completely maintained operational integrity, and guaranteed the necessary level of civilian protection—demonstrating extraordinary strength and resilience under loads more than 10 times higher than DSTU 9329:2025 requirements.

The ARCA NOVA shelter stands as one of the most technologically advanced solutions on the Ukrainian shelter market:

• successfully blast-tested against the high-explosive fragmentation warhead of a Shahed-136 strike UAV (47.8 kg), as officially documented in the Test Report;
• features a test-proven 13-fold margin of structural safety;
• holds Ukraine's highest protection class rating: A-I+, withstanding peak air blast overpressures of over 500 (1300) kPa;
• equipped with TriCore Armor—a proprietary continuous double three-tier reinforcement cage engineered for maximum structural integrity and supplemental protection against tipping and progressive collapse. Under severe explosions, the hazard often stems not from the primary impact, but from cascade structural failure. The TriCore Armor reinforcement cage maintains structural geometry even under partial damage, enhances interior safety, preserves airtight sealing, and provides reinforced geometric stability of the doorway frame to prevent exit blockage;
• features an integrated Dual Armor engineering system—a doubled reinforcement area for enhanced protection, engineered for elevated structural strength, superior load distribution, and augmented containment of shrapnel damage under modern military threat conditions. This ensures significantly higher resistance to blast waves at peak loads, distributes impact energy more effectively, lowers the risk of localized failure, minimizes secondary shrapnel hazards, and inhibits crack formation;
• equipped with the Blast Comfort anti-blast valve, which effectively dampens blast waves and reduces overpressure—protecting occupants from critical shock loads while ensuring higher safety and comfort levels inside the shelter;
• equipped with protective doors featuring enhanced overpressure blast wave protection up to 800 kPa, or
• upon request, equipped with BlastLock reinforced protective doors with concrete inserts, blast-tested against the warhead of a Shahed-136. The reinforced concrete core creates an upgraded barrier against fragmentation, enhancing the door's capacity to intercept shrapnel, secondary projectiles, and extreme stress loads—maximizing entry group resistance against shock waves and preserving the shelter's protective envelope;
• offered in three equipment configurations: SAFE CORE, COMFORT, and PREMIUM.

Protection class: A-II, A-III, A-IV. Withstands an overpressure from an air shock wave of over 300 kPa. Reduction of radiation exposure up to Kf = 5000 is possible.
