Efficient cooling through direct contact

A particularly high COP efficiency is achieved by the direct contact of the device surface with the component or object to be tempered. This is due to the fact that efficiency losses are avoided by the usually necessary circulation of an intermediately acting coolant – be it air or a liquid. Properly used, a higher COP efficiency is achieved, allowing applications with particularly high temperature output to be cooled efficiently, as is the case with frequency converters, for example.

Additional efficiency is provided by the thermal conducting foil supplied as standard. This ensures optimum contact with the surface, especially on surfaces with a higher degree of roughness.

Different application areas require adaptable solutions

It goes without saying that our product range must be adapted to the various fields of application of our customers in order to be able to offer you optimum results. Our surface coolers are therefore available in power ranges from 50W-400W input power in three different sizes. This enables us to serve a wide range of applications from small, precisely temperature-controlled laboratory applications to the cooling of devices with particularly high energy output.

Our Peltier surface coolers can also be adapted to your application through various configuration options. On request, our Peltier surface coolers can also be equipped with a stainless steel hood in addition to the standard version. In addition, our Peltier coolers can be designed to be salt mist proof or protected against sandstorms on request. Of course, a thermostat-controlled duty cycle, the changeover to heating operation and the associated control electronics and integrated power supply units can also be implemented on request – individually adapted to your requirements.

Important for you: High degree of protection – Our task: low temperature

Sometimes cuts in a switch cabinet are not permitted. This is particularly the case if your application and thus your cabinet or container requires a certain protection class which does not permit such incisions or openings. Since our surface coolers do not require air circulation on the cooled surface, cuts and openings can be dispensed with. In applications which also do not permit screwed mounting, an adhesive mounting can also be used, whereby mounting of our Peltier surface coolers is possible without any openings at all. Unfortunately, protection classes do not take the internal temperature of your cabinet into account. We do! Our Peltier surface temperature control thus allows the uncompromising temperature control of switch cabinets of different protection classes, without negatively influencing the latter and still effectively protects your control electronics.

Take advantage of the Peltier technology!

Like our other Peltier units, our Peltier surface coolers also benefit from the advantages of Peltier technology in terms of efficiency, simplicity, durability and low maintenance. This means that our Peltier surface coolers can also be installed in any position without the need for any type of coolant. This not only reduces the complexity and thus the susceptibility to errors of the system, but also benefits the environment. Peltier technology is also characterised by a particularly high degree of efficiency in various applications. Peltier technology can be used to cover a large part of the commercially required cooling and temperature control in the electronics and laboratory sectors, and Peltier cooling units can also be used to implement solutions that would otherwise simply not be possible. It should also be mentioned that all of our Peltier surface coolers can be easily converted from cooling to heating operation, since only the current flow direction has to be changed. Of course, we also supply you with the necessary control electronics in this connection.

Small livestock also makes a mess: Accessories can make the difference

Even if we try to offer you the technically and qualitatively best solution with our Peltier cooling units, our units, like all technical products, must operate in the right environment. In order to avoid errors, we can supply you with the appropriate control electronics, thermostats, regulators, mounting material, insulation material and much more. Do not hesitate to contact us: We will not only be happy to advise you in all matters without obligation, but can also offer you the optimum complete solution to avoid unpleasant surprises and problems.

Our quality promise

At Dr. Neumann Peltier-Technik, we do everything we can to offer you a product of the highest quality, no matter which product it is. As with our Peltier switch cabinet coolers, our Peltier surface coolers are IP-67 protected and therefore insensitive to exogenous influences. In addition, all our Peltier products are checked for their functionality and in particular their efficiency before shipping. In the unlikely event that a fault should occur during operation, our coolers are equipped as standard with overheating protection and a fault alarm contact. This prevents damage to the unit due to overheating, and additionally a fault in the unit is reported so that you immediately become aware of it. Furthermore almost all our products are UL-certified.

However, our quality philosophy is not only reflected in our products themselves. As Dr. Neumann Peltier-Technik GmbH, we hold both ISO 9001 and Ohris certification.

Of course, we always have an open ear for our customers: It is also part of our quality policy to support you with every application and every new idea.
