Franz-Isella (FI), Italy - Passive Cooled Shelters: FI is the world leader in design and manufacturing of Passive Cooling Shelters. Electronic equipment is supposed to perform reliably over long periods of time in unmanned isolated and hardly accessible locations. Telecommunications is the area where such situations are most frequently found. Equipment reliability is stressed to the limit at the design stage. However, much of the actual performance depends on the environment in which the equipment is required to operate. Each location has its own microclimate, quite often a harsh one and nothing can be done to change it. In such cases, FI provides passive cooling shelter solutions.

Passive Cooling is the clever use of a few well-known physical phenomena in order to;

• Limit the range of temperature oscillations inside the Shelter regardless of daily thermal excursions,
• Provide an easy way to remove heat by transferring it from inside to outside the shelter.

The first objective is achieved by combining thermal insulation with heat capacity. Shelter walls are the sandwich type and contain the proper thickness of insulating material. Heat capacity is provided by adding a water tank, since water has the highest known specific heat over a wide temperature range. In special cases, Phase Change Materials are used for this purpose. In fact, at certain well-defined temperature levels, these materials show an even higher apparent heat than water. However, this only occurs within very narrow temperature ranges owing to the latent heat involved in phase changes at these temperatures.
Second objective is achieved by naturally circulating water through a circuit where different levels correspond to different temperatures. This scheme is well-known under the name of Thermosiphon.

In a wide range of conditions, including desert climates or other geographic locations where daily temperature excursions are high, Passive cooling offers the most reliable and cost-effective solution for a favorable environment for electronic equipment. Shelter Passive Cooling relies on high technological standards, offers the longest operating life for telecommunication stations. In conclusion, passively cooled Shelters truly deserve to be defined as Shelters.
The Passive Cooled Shelters are custom designed and manufactured based the heat dissipation characteristic of equipment to be in housed and the ambient temperature required.

Application of Passive Cooled Shelters: Microwave stations, Satellite communication - Earth stations, Base repeater stations, Power stations, Switching stations, Gas & Oil pipelines SCADA station.
