About Laird Laird is a global technology company focused on providing systems, components and solutions that protect electronics from electromagnetic interference and heat, and that enable connectivity in mission-critical wireless applications and antenna systems. We are a global leader in the field of radio frequency (RF) engineering and in the design, development and supply of innovative technology that allows people, organisations and applications to connect efficiently. Thermoelectric Assemblies (TEAs) are compact units that control the temperature of a wide variety of applications, such...

There are five distinct TEA product families that were designed for a specific cooling capacity range, temperature differential range or tight space constraint. The diagram to the right is a perceptual map of a cooling spectrum that can be used to guide designers to a particular product family that will have the desired attributes that the application requires. Thermoelectric Applications Cascade Series 35 – 60 Watts Temperature Differential (ΔT) Laird offers the widest selection of TEAs on the market. Products are designed and manufactured to strict process control standards and pass/ fail criteria,...

Power Cool Series The Power Cool Series offers the widest selection of cooling capacities ranging from 20 to 193 Watts. The TEAs use impingement flow to dissipate heat on the hot side. The cold side heat transfer mechanism can absorb heat using convection (heat sink and fan), conduction (cold plate), or liquid (heat exchanger) means. This product series is offered in 12 or 24 VDC configurations. For 100 Watt systems and higher, 48 VDC is available. The Power Cool Series is designed for indoor use in the medical, analytical, and industrial markets. Air-to-Air Assemblies offer dependable, compact...

Power Cool Series Liquid-to-Air Systems (LA) Liquid-to-Air Assemblies cool or heat liquids that flow through a heat exchanger. The liquid heat exchanger is designed for a re-circulating system, absorbs heat and pumps it through the TEM, where it dissipates into the outside environment through an air heat exchanger. Specifications apply to an ambient temperature of 32°C and nominal voltage with tolerances ±10%. Tunnel Series The Tunnel Series TEAs are designed with a patented, high-performance cross flow technology that maximizes heat transfer when pulling air through a heat exchanger. The number...

Outdoor Cooler Series The Outdoor Cooler Series is designed for outdoor use to control the temperature of electronic cabinets. The product series has been designed to pass harsh environmental demands such as earthquake resistance, salt fog, wind-driven rain, high temperature exposure and dust. The cooling capacity ranges from 100 to 250 Watts. This product series is offered in 24 and 48 VDC configurations and is designed for outdoor use in the telecom and industrial markets. As a standard option products are also sold with bi-polar thermostatic control to heat and cool to specific temperature...

Direct-to-Liquid Assemblies cool or heat objects attached directly to the cold plate. Heat is dissipated into a liquid heat exchanger on the hot side. The liquid circuit is normally a re-circulating type that requires a pump and additional liquid heat exchanger that dissipates heat into the ambient environment. Specifications apply to the warm side liquid temperature of 32°C and nominal voltage with tolerances ±10%. Lw Temperature Controllers Laird offers three types of controllers to drive TEAs. The Q Series is designed for single directional thermostatic control. The PR Series is designed for...

CONNECTED MEDICAL | MOBILE DEVICES | TELECOM COMPUTING | CONNECTED INDUSTRY | CONNECTED TRANSPORT Since there are so many unique attributes that need to be ascertained for each application, often a customized TEA will yield a more optimal thermal solution. Laird offers strong engineering services with a global presence that supports onsite concept generation, thermal modeling, thermal design and rapid prototyping. We also offer validation test services to meet unique compliance standards for each industry, such as Telcordia, MIL-STDs or unique standards specific to a medical, automotive or industrial...
