Peltier elements are electrothermal transducers which generate a temperature difference when electricity flows through them. The current direction determines whether cooling or heating is required. For simple elements the temperature difference can be up to 73 Kelvin, for multistage elements up to 114 Kelvin. They can be used in a wide range of applications, from cooling accumulators, charging laboratory diagnostics and polymerase chain reactions in thermal cyclers. In a nutshell: Wherever maximum precision is required for temperature control in the smallest possible space.

Although the Peltier effect can also generate heat, it is largely used to transport heat safely and easily. Peltier elements can be used in a variety of applications, even independent of terrestrial gravity and weightlessness. They operate completely silent and vibration-free. Maximum flexibility is achieved with the smallest dimensions. In addition, thermoelectric generators enable electrical energy to be generated directly from heat.

Our Peltier elements are constantly being further developed and adapted to the needs of our customers. The production is not only subject to the high technological standard of Quick-Ohm products, but is also ISO 9001:2000 certified. Each production step is continuously monitored and concluded with a quality check. Ultrasonic and temperature tests are carried out for all parameters and the electrical properties are tested. In the manufacturing process, the best raw materials are used, which can be obtained from selected suppliers worldwide. This also applies to ceramic substrates and accessories.

With a large selection and the possibility to work entirely according to customer wishes, we will find the most suitable solution for your project. All necessary parameters are calculated in order to find the right Peltier element for you, adjusted to maximum cooling capacity or maximum energy efficiency.

Depending on the application, this can be specially designed for cyclic operation, protected against corrosion and moisture or suitable for high temperatures (up to 200 degrees Celsius).

Mounting material / TIM

Due to the relatively fragile semiconductor elements and ceramic plates, care must be taken when installing the Peltier element. If the proper mounting material is used, installation can begin. Heat conducting media placed between the heat sink and the mounting location will help compensate for unevenness and provide the best possible contact between both surfaces by displacing trapped air. In addition, thermal conductive material compensates for the thermal expansion of different materials. The most common installation method is to clamp the Peltier element between the heat sink and the cooling surface. This connection is fixed by clamping screws. In this case, it is extremely important that the required clamping force is maintained, regardless of the number of clamping screws. It is between 150 and 200N/cm². This value not only results in a secure hold, but also minimizes the thermal resistance of the thermal compound and is indispensable for ideal operation.

Printing service

The screen printing process enables us to print a phase-change material (PCM) directly onto the Peltier element. This material has the specific characteristic to be dry and mouldable at room temperature. Only at a pressure of 30N/cm² at approximately 45 degrees Celsius does the application become active when installed and change the aggregate state. The PCM becomes fluid and adapts ideally to the conditions of the respective surfaces. This fills gaps and cavities in the best possible way. Screen printing also has the advantage that the job can be reproduced by the printing process and is designed for mass production. This makes the use of conventional heat conducting paste (WLP) unnecessary.

Heat pipe heat sink

Heat pipes or heat pipes allow the efficient transport of heat or cold to the heat sink. They allow highly efficient cooling solutions to be implemented. These outperform conventional cooling elements made of extruded aluminium profiles in terms of design and performance. In Peltier applications, effective heat dissipation is essential as they depend on the temperature difference. Peltier elements can only produce a certain difference in heat flow from the cold to the warm side. This means that the warmer the hot side, the less cold the opposite side is.

We will be happy to select and design the right heat sink for your application or optimize your existing system.


We use a CFD tool (Computational Fluid Dynamics) for the optimal design of thermal management systems. This enables us to simulate thermal systems with the help of numerical fluid mechanics and to avoid possible complications in advance. In this way, cooling systems can be designed more precisely and adapted to the necessary requirements in the best possible way. Using this method, each design can be tested for weak points in a simulated test environment before production begins. As a result, the realization of a prototype can be reduced to a minimum and development costs can be reduced efficiently.
