APPLICATION

Our nuclear, biological and chemical (NBC) filtration system provides clean filtered fresh air, free from NBC contaminates in an over pressure citadel. Three levels of filtration (coalescer, dust, and composite filtration) is applied to incoming air before being supplied to the citadel. The over pressure citadel removes the need for occupants to wear gas masks and protective clothing during NBC attacks. Two modes of operation allows clean fresh air to be supplied during peace time, or conventional combat times, and filtered fresh air during NBC warfare.The control system constantly compares inside and outside pressures, and should the citadel pressurization fail, provide a visual and/or audible warning.The NBC filter unit is designed for external installation to citadels with a supply duct to the citadel interior. The NBC control unit is designed to be installed internally within the citadel covering the air duct to diffuse air entering the citadel. When the NBC filter unit is operational the unit is designed as a fail-safe system, i.e. should the unit sustain damage or an air seal leak, then clean air will leak out of the unit rather than contaminated air being drawn in.

INTRODUCTION

Naval vessels have to operate now a day more and more under the threat of an attack by TIC’s and TIM’s. To be able to operate under these circumstances without being contaminated, reliable NBC filter systems are of the essence. With our NBC filter units, provided with STANAG4447 filter elements, in combination with our

overpressure controllers, a safe operating environment (citadel) is created, ensuring the optimal performance of the crew and electronic equipment. Our NBC filter units are available in a capacity range of 900 up to 1800m3/h.
