1 Application

Designed for installation of small devices (transmitters or electronic modules) with heat dissipation of 10 W or less to maintain the temperature of the electronics 10 K below the peak ambient temperature.

2 Advantages

• No energy or power supply required • Cost effective • Maintenance free • IP65 up to IP68 , no fan or louvers to reduce

the IP rating • Very rugged design • Solid state, no moving parts

3 Components

All components are designed for optimal performance:

• ‘Arctic PP’ enclosures with excellent insulation properties and no heat sinks

• PCM ( phase change material ), a material that ‘melts’ and ‘freezes’ at 93 F/ 34°C and stores the resulting energy at this level

• Optimal installation: no heat sinks to ambient conditions, good heat transfer between instrument and PCM due to heat conduction.

• Sun shade, not only on top of the enclosure, but along sides, if necessary
