2.3.2 Container Shelter
See Figs. 2−3, 2−4, 2−5.
The Navaids 400 equipment can be supplied already installed in a 10 ft Standard Navaids Shelter
(type 1D). To cover the requirements the shelter is based on the definition on transport containers
ISO/DIN standards. The shelter consists of a self−supporting, distortion resistant aluminium frame
construction with eight ISO corners and walls made of sandwich panels in standardized container
dimensions.
During installation, the shelter should be placed on the foundations such that the door is oriented
according to the site survey and project drawings. The shelter is anchored to the four foundation
blocks using the ISO corners and twist locks. The roof of the shelter can be walked on. The shelter
itself is splash−proof, resistant against to a marine climate and insensitive to salt water, fungus and
termites.
A complete electrical installation is already provided which can easily be adapted to specific project
requirements. The battery box, which is hermetically sealed from the interior in its operating state, is
accessible from the inside of the shelter and ventilated from the outside. Its shelf−type construction
provides space for a block of batteries (48 V, 256 Ah max.) for the Navaids 400 installation as well as
for collocated equipment. Ventilation is provided by one or two through−the−wall air conditioning
units and thermostat. The air conditioning equipment is designed to fulfil the environmental condi-
tions for all products installed in the container. One fire extinguisher is provided. The power supply
(mains) and signal (RC, field monitor) feeder cables enter from below through openings in the shelter
floor.
When transporting the shelter by crane or helicopter, care should be taken to ensure that the angle
between the lifting harness and the crate is at least 60° (see Fig. 2−3).
