Introduction

BETEC CAD. has been leader for over 20 years, in designing, manufacturing, durable, high performance control Dampers for industrial and commercial building ventilation applications. Constructed from heavy-duty, high quality steel with the most advanced equipments in the industry. BETEC CAD. dampers can stand up to the toughest and most demanding environments and can be custom-built to meet the exact needs of virtually any ventilation or process applications.
BETEC CAD. manufactures, UL classified dampers to meet the standards of NFPA - National Fire Protection Authority,for human life and property safety. To meet the demands of fire and smoke protection, these dampers are available in a wide range of classifications and with a variety of custom built features and options.
BETEC CAD. fire dampers are designed to operate as an integral part of Engineered smoke management system for building controls, and are used in walls, ceiling and floors. They are suitable for both dynamic or static fan on systems. Fire Dampers are required by the International Uniform Building Code to maintain the required fire resistance rating of walls, partitions and floors when they are penetrated by air ducts or other ventilation openings.
A duct or ventilation openings in any of the fire rated partitions would permit a fire to spread from the compartment of origin to adjoining compartments or space. Fire Dampers or Fire-Smoke dampers are installed in these ducts or venti- lation openings. They close automatically upon detection of heat by a Thermal responsive device (TRD), blocking the openings and preventing the spread of fire or smoke in to the adjoining compartment.
BETEC CAO’s experienced and professional team provide quality products through continuous commitment to research and development and the introduction of new technologies.

Fire-resistive construction requirements usually are determined by the local or state code authority. Local and state codes are usually adaptations of the national and model codes, such as the International Building Code, published by the International Code Council, Inc. (ICC); BOCA National Building Code published by the Building Officials and Code Administrators International, Inc. (BOCA); the Uniform Building Code published by the International Conference of Building Officials (ICBO); and the Standard Building Code published by the Southern Building Code Congress International, Inc. (SBCCI).
The National Fire Codes published by the National Fire Protection Association (NFPA) contain recommended practices and technical data for determining fire-resistive requirements. Standards for fire-resistive tests may be found through the American National Standards Institute (ANSI), ASTM, UL, and the NFPA.
Testing of fire-resistive components and assemblies may be conducted by any of several independent testing laboratories. The most prominent testing laboratories evaluating fire resistive materials and assemblies are UL - Under Writers Laboratories of USA.
