Thermoelectric Modules also known as TEM, TEC and Peltier cooler/devices are available in a wide array of sizes, operating voltage, current and cooling capacity. Produced using Crystal LTD’s high performing thermoelectric elements, our TEM offering are well suited for cooling/heating, thermal cycling, high power density and power generation applications. The product line features miniature, multistage, annular and center hole types with options for continuous operation up to 150°C. Options include high tolerance lapping, epoxy and silicone moisture seal, and wiring in kits/arrays.
Thermoelectric Generators Modules and Assemblies are designed for power generation at temperatures up to 570°C. Crystal LTD’s G Series TEG modules and H series cooling modules offer high efficiency in power generation applications at temperatures up to 150°C. Options include wiring in kits or production of customized assemblies.
A wide variety of standard thermoelectric assemblies (TEA) are available through the Adcol product line. The standard offing includes TEA types: Air to Air in sizes from 15 to 200 watts, Air to Plate in sizes from 42 to 80 watts and Liquid to Air in sizes from 50 to 300 watts. We offer rapid prototyping for custom designs and a strong supply chain for high quality components at extremely competitive prices. Located in Guangzhou, China we have strong ties to the world’s leading manufacturers of thermal management components. Align Sourcing/Adcol USA provides day to day support to customers in the Americas. Align Sourcing provides end to end logistical support from order placement to delivery for convenience and lowest landed cost. We support managed inventory programs and maintain inventory of standard products to minimize lead-time.
Our TIM offering is designed for compatibility with Thermoelectric Modules (TEM), Thermoelectric Assemblies (TEA) and Heat Sinks. TIMs are designed to improve heat transfer by filling gaps with thermally conductive materials reducing thermal resistance and improving thermal performance. TIM materials are available in the form of thermal grease/compounds, Epoxy and thermally conductive graphite foils. We have custom formulating capabilities and production in the USA and China through EMS.
Our focus is on high density heat sinks for Thermoelectric Assemblies and other power applications. Extruded, Bonded Fin, Skived, brazed/solder fin types are available. Cold Plates, Spacer Blocks, Liquid Cold Plates and CNC machined metal component are also available. We typically supply the completed part ready for assembly for the greatest cost savings. CNC machining, plating, anodize, chromate and powder coating finishing is available. Techsource Thermal Solutions is a leading heat sink manufacture represented by Align Sourcing. We also offer heat sinks from Adcol and other sources.

Since 1998 Crystal Ltd. has been producing thermoelectric elements of different cross-section and height. A unique technology allows growing the plates of thermoelectric material with defined width that forms one of the sizes of thermoelectric element (dice, pellet). It requires further only two cutting operations to form element’s length and height. In result the elements have exact geometric dimensions.
An improved method of electro-erosive cutting technology is used to cut plates of thermoelectric material into elements with high accuracy of geometric dimensions and high quality of the surface after cutting.
Taking into consideration the above-mentioned features of thermoelectric elements, the several Ni-based coatings have been developed to use the elements for assembling the modules used in various applications. Crystal Ltd’s own mass-production factory manufactures a wide range of thermoelectric modules in practically any necessary volumes.
All elements have the barrier antidiffusion coating fully compatible with RoHS requirements and modules assembling processes using lead-free solders.
Crystal Ltd. offers at the market a wide range of thermoelectric elements (based on Bi2Te3 solid solutions) and modules both for cooling and power generation. An original patented technology of thermoelectric material crystallization from a liquid melt in a flat cavity provides thermoelectric elements (TE) with a crystalline structure oriented strictly along direction of current providing a unique combination of thermoelectric and mechanical properties. The special methods of barrier multilayered Nickel and Molybdenum coatings deposition in vacuum also provide outstanding lifetime and thermal stability of elements and modules.
