| Description |
First produced in 1938, the SPEICH Clear view screen
is a high technology product, carefully engineered in
all it's details and designed according to ISO 3904.
Many decades of field experience and constant
technical improvements have made the SPEICH Clear view
screen extremely reliable and durable even under the
severe environment conditions.
Tens of thousand units have been supplied all over the
world and are installed on alI kind of merchant and
military ships, yachts and tugboats.
Schematically, SPEICH Clear view screen keeps a glass
disk free from rain, snow or sea-water by fast
rotation.
The motor is placed in the center and is fastened to
the fixed glass so as to obtain the largest possible
field of vision.
This particular assembly also makes the unit water and
airtight, thus making it suitable for pressurised and
air-conditioning bridges. The rotating glass is
hardened and opticaly rectified to avoid any optical
distortion. The electric motor is available for many
tensions; the rotor is tropicalized and turns on
silent ball-bearings.
All metal parts are made of brass; a specially
designed manifold between the ring surrounding the
rotating glass and the fixed frame keeps water from
entering the space between the fixed and rotating
glass. This space can optionally be heated by electric
resistance to avoid condensation and ice formation,
which could prevent proper operation counter-ring. |
