CHAPTER 7<br />

OPERATING ENVIRONMENT<br />

The <strong>MAWS</strong> HydroMet systems have been especially designed <strong>for</strong><br />

unattended operation at remote locations. Only minimum maintenance<br />

is required annually.<br />

Operating temperature<br />

The <strong>MAWS</strong> systems have a wide operating temperature of -35° to +<br />

55° C (extended range at request). When installed outside, it is<br />

recommended that the enclosure is equipped with a white radiation<br />

shield, efficiently protecting the enclosure against excessive sun<br />

radiation, falling ice in tower installations etc. The shield also<br />

minimizes the temperature differences between day <strong>and</strong> night, thus<br />

preventing condensation inside the enclosure. This, together with the<br />

GoreTex membrane filter, guarantees that no extra drying agent bags<br />

are required inside the enclose to keep it dry.<br />
