Fusite

Fusite's initiator assemblies are the primary component in a variety of electrically stimulated initiation devices. They consist of a metal outer ring and a center pole, which are completely separated by glass insulation. Connecting the inner and outer conductive parts is a very fine 1 Ohm bridge wire, which heats up as an electrical current is passed through it, and upon direct contact, a suitable pyrotechnic compound is initiated. Our initiator seals and components come with the highest levels of stable insulation and corrosion- and pressure-resistance, as well as a long storage life of up to ten years and hermetic protection against moisture. Fusite adds value by welding the bridge wire onto the GTM seal to achieve a customized electrical resistance rating. Fully automatic processes guarantee tight tolerances, with 100% automatic testing included. Applications Fusite's initiator technology is used when highly reliable and precise pyrotechnic ignition is needed. Our initiator components are used in the squib explosive devices found in the infrared (IR) flare housings that are used as countermeasures for decoying heat-seeking incoming missiles as well as for propulsion in chaff cartridge case assemblies that release radar reflecting materials for the protection of aircraft from ground radars.

Fusite manufactures premium glass-to-metal (GTM) hermetic seals, connectors, feedthroughs, and related components for air conditioning and refrigeration applications. When high reliability throughout the lifecycle of a compressor or pump is needed, Fusite is one of the world's most trusted sources, ensuring consistent quality no matter what size the order. In environments where refrigerants or other compressed materials are contained in a sealed system, our GTM hermetic feedthroughs allow a secure and reliable means to pass electrical power from an outside source to the motor inside. We produce feedthroughs for everything from fractional 14 horsepower electric motors (up to 300 volts), all the way up to large 75 horsepower commercial integral motors (up to 600 volts). Primary Applications As a worldwide leader in glass-to-metal hermetic seals for refrigerator, freezer, and air conditioning compressor applications, Fusite manufactures hundreds of millions of compressor feedthroughs each year. Our feedthroughs are also used in vending machines, heat pumps, and other pressurized systems. Other Application Areas In addition to feedthroughs that meet a variety of commonly used refrigerants (such as R22, R134a, R410a), Fusite has developed products for higher pressure applications such as CO2.

Relying on 70 years of experience in manufacturing premium glass-to-metal (GTM) hermetic seals for ACR applications, Fusite designed the first feedthrough in the world for use in hybrid electric vehicle air conditioning (AC) compressors. We continue to provide innovative GTM products and solutions, such as electrically driven AC compressors, to most of the existing and emerging hybrid and all-electric vehicle OEMs around the globe. Applications Fusite GTM feedthroughs are custom designed for hybrid vehicle and all-electric vehicle AC compressors. Typical Specifications Hermeticity: Insulation resistance: > 10, 000 megohm @ 500 VDC Dielectric voltage: 2500 volts @ Burst pressure: Should be verified in customer specific applications.

Fusite designs and develops custom glass-to-metal (GTM) feedthroughs for use in the industrial and commercial pump industry to meet the specific application requirements of our customers. Our feedthroughs stand up to harsh environments and meet the durability and high reliability requirements of major pump OEMs around the world. Applications Fusite GTM feedthroughs are custom designed for various pump applications, including water pumps, slurry pumps, chemical pumps, and mixed-use pumps. Typical Specifications Hermeticity: Insulation resistance: > 10, 000 megohm @ 500 VDC Dielectric voltage: 2500 volts @ Burst pressure: Typical GTM seals meet or exceed 2, 250 psi pressure test, but should be verified in customer specific applications Regulatory: Recognized by global regulatory agencies such as UL

Fusite uses its leading-edge glass-to-metal (GTM) sealing process to create highly compressed seals for hermetic sight glasses that are used as windows for visual level and flow indicators in high-pressure or vacuum applications. We offer a variety of bolt-on, weld-in, and threaded configurations. Standard models include single port glasses for simple level checking and multiple port glasses for more complex systems. Applications Fusite sight glasses can be used to check liquid levels in pumps, compressors, or other components requiring visual level or flow checks. Typically sight glasses utilize thread and hexagon bodies for flat gasket seals, with flange-type bodies for bolt mounting for "O" ring seals, and also for solder mounting and resistance welding. Typical Specifications Hermeticity:

Fusite manufactures battery seals designed for extreme temperature environments and long-endurance applications. Fusite’s glass-to-metal seals can also withstand the harshest corrosives. Fusite employs specialized high-volume manufacturing processes and techniques, such as proprietary corrosion-resistant glasses, vision inspection, and vibratory assembly machinery. This provides the best overall value and highest reliability whether the requirement is for a small quantity of prototypes or millions of units. Applications Fusite high reliability battery seals and lids are used worldwide in aerospace power and automotive mixed-use applications, as well as military hand-held radio communications, surveillance systems, and battery back-up systems. Typical Specifications With long-proven industry experience, Fusite is able to combine pure metals ( such as molybdenum used in feedthrough pins and stainless or cold-rolled steel used in battery bodies) with highly durable glasses (as inTA-23) in battery seals and lids for the utmost in reliability, performance, and durability. Models can be either resistance- or laser-welded onto a battery lid For any application requiring hermetic battery seals, lids, terminals, or batteries requiring lithium or silver-zinc hermetic seals
