Air to air thermal management assemblies like our range of cabinet coolers and dehumidifiers are the ideal solution to cool and remove heat from cabinets, control panels and consoles. Utilizing either Peltier, heat pipe or compressor technology, our cabinet coolers are especially suitable for harsh environments like food industry or traffic engineering. Internal air circulation and ambient external air flow are separated by a hermetical seal. Most of our cabinet coolers are also protected against water and rated according to the IP67 (NEMA4X) standard.
Common mounting locations for flush mount cabinet coolers are side, front or back as high as possible on the cabinet and with no intrusion into the enclosure. Drop in air-to-air heat exchangers extend into the panel from the side, top, front or back, but minimise the external footprint.
Thermoelectric Based Cabinet Coolers
Thermoelectric cabinet coolers are the ideal solution when heat needs to be removed from small electronic cabinets, or small compartments need to be cooled below ambient. Nominal cooling capacities range from 30 W to 280 W when internal temperature equals external temperature (Tin = Tamb). When cooling below ambient is required, the cooling capacity depends on the size of the compartment and its insulation. Temperatures of as low as 25 K below ambient temperatures can be achieved.
Heat Pipe Based Cabinet Coolers
Based on heat pipe technology, these very compact and lightweight air to air heat exchangers remove waste heat from sealed electrical panels and enclosures. Intruding and flush-mount versions are available with ratings from 16 W/°C up to 200 W/°C. The coolers’ design dissipates heat from sensitive electronic components without exposing them to the harsh and dirty environment outside the cabinet. Common mounting locations for these units are side, front or back as high as possible on the enclosure.
Compressor Based Cabinet Coolers
Our DEK Compressor Based Cabinet Coolers can be mounted on the roof of the cabinet. Available for different operating voltages, the compressor cooling units provide nominal cooling capacities of 410 W or 820 W respectively. Among the main product features are a quick assembly procedure, high reliability and minimized maintenance efforts.
Humidity inside the cabinet can damage sensitive electronics or optics, so reliable dehumdification of the air in a cabinet is critical. The PSE 30 dehumidifier series, which uses maintenance-free Peltier technology, is suitable for collecting and draining condensate from the housing. When warm and humid air flow in the cabinet passes over the PSE unit, it condenses on its cold surface. The condensate is collected and reliably pumped to the outside by a diaphragm pump. The unit is suitable for mounting partially inside or completely inside the cabinet.
