Laird designs and manufactures some of the world’s highest-rated broad range of thermoelectric modules and thermal assemblies for medical, telecom applications, instrumentation, and other applications.
Laird not only makes its own modules, but combines them with in-house design, assembly, and manufacturing expertise.
Thermoelectric Assemblies (TEA)

Liquid Cooling Systems (LCS)
Thermoelectric Assemblies (TEA)
Laird offers the widest selection of T
EAs on the market. Products are designed and manufactured to strict process control standards and pass/fail criteria, assuring that our customers receive the best possible TEAs.
Laird`s standard product portfolio includes an extensive array of thermal management solutions that cover a wide range of cooling capacities with compact form factors and high coefficient of performance.
Standard operating voltages are 12 and 24 VDC, and on larger models 48 VDC.
All products are manufactured in an ISO 9001:2008 certified facility and are designed to meet the cooling needs of many thermal management applications in the medical, analytical, industrial and telecom markets.CUSTOMIZATION
Laird offers strong engineering services with a global presence that supports onsite concept generation, thermal modeling, thermal design and rapid prototyping.
Laird also offer validation test services to meet unique compliance standards for each industry, such as Telcordia, MIL-STDs or unique standards specific to medical, automotive or industrial accounts.
Minimum order quantity (MOQ) applies for all custom TEA designs and validation testing.
Thermoelectric Modules (TEM)
Laird designs and manufactures thermoelectric modules (TEMs)
Our extensive standard product portfolio covers a wide range of cooling capacities, temperature differentials, input power constraints and geometric footprints.
Standard finishing options are available to accommodate alternate lead lengths, lapping thickness tolerances, and moisture protective sealants.
Standard pre-tinning and solder constructions are available to accommodate solder-able mounting of the TEM to the heat exchanger, or processing of TEM through a reflow oven to solder the end assembly.CUSTOMIZATION
Since there are so many unique attributes that need to be ascertained for each application, often a customized TEM 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 account.

Laird's temperature controllers are specifically designed to control thermoelectric assemblies, (TEAs) in a closed loop system.
Feedback from a temperature sensor is used to vary the output of the power supply to control the temperature of an enclosure.
Laird offers three types of controllers:
Single Directional Thermostatic,
⦁ Bi-Directional Thermostatic, and
⦁ Proportional Integral Derivative (PID) (Programmable).
A Single Directional Thermostatic Controller
can maintain a constant temperature set point within an enclosure surrounded by a relatively constant ambient temperature.
The set point tolerance is defined by a hysteresis range.
Once the set point is achieved, the controller shuts off the TEA.
When the control temperature changes to outside the hysteresis range, the controller turns on power to the TEA and restarts the cooling mode process. This cycle continues until the controller is shut down.
Thermostatic control is often used in refrigeration mode in an indoor environment with climate control, where a narrow temperature swing can be tolerated.
Laird offers two standard single directional thermostatic temperature controllers, QC-50 and QE-50.A Bi-Directional Thermostatic Controller
operates in the same manner as a Single Directional Controller, except output can operate in both Heating and Cooling mode.
Controllers with a bi-directional output are used for maintaining a constant temperature within an enclosure surrounded by an ambient environment with a much larger temperature swing.
This is commonly experienced in an outdoor environment.
Laird offers a microcontroller based device with integrated temperature control for cooling and heating of thermoelectric assemblies requiring precise temperature control.
The TC-XX-SR-54 has 3 programmable fan outputs, alarm output relay and alarm condition LEDs.
The parameters will be programmed by Laird according to customer specifications.Proportional Controllers
use proportional regulation to maintain a constant temperature with no swing in the control temperature.
This is accomplished by using a PID algorithm to determine the output value and a Pulse Width Modulation (PWM) output to handle the physical control.
Proportional Controllers are often used in heating and cooling systems where the temperature must stay constant (with no change) regardless of the change in ambient temperature.
Laird offers two standard programmable controllers.
- The PR-59 is mountable at system level and comes with software to connect to PC. Settings can be adjusted while running TEA, which is beneficial for product development.
- The MTTC-1410 is a simpler bench top controller that can control TEA to specific set point by push button control.
Temperature controllers can accommodate more advanced options. Outputs are available for fan, thermoelectric module, thermistor, tachometer sensor on fan, overheating thermostat switch, alarm and LED.
However, interface with Laird is required to customize temperature controller settings to meet your unique application requirements.
Liquid Cooling Systems(LCS)
Laird has more than 35 years of experience in the design, manufacture and servicing of liquid cooling systems for various high end markets.
All products are manufactured in an ISO 9001 and ISO 14001 certified facility and are built to meet the needs of strict process control requirements found in many of the medical, industrial, and semiconductor industries.
Since there are many unique attributes that need to be ascertained from each application, often a liquid cooling solution requires a custom configuration to optimize performance and assure maximum system uptime.
Laird has the know-how to design cooling systems that are compatible with water, water-glycol, transformer oil or various corrosion prohibitors.
LCS can also be quite complex and require temperature control of multiple liquid circuits or multiple pressure drop settings in order to accommodate low and high pressure conditions.
Laird has experience with both and offers strong engineering design services with a global presence that supports onsite concept generation, thermal modeling, mechanical and electrical design and rapid prototyping.
Minimum order quantity (MOQ) applies for all custom LCS designs and validation testing.
