Produced since 1938, SPEICH Clear
view screen is a hightechnology product, carefully engineered in all details.
Many decades of field, experience and constant technical improvements make
SPEICH Clear view screen extremely reliable and durable in the most severe
environment conditions.
Tens of thousand units have
been supplied all over the world and are installed on all 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 to maintain the largest possible
sight field.
This particular assembly also
makes the unit water and airtight, thus making it suited to pressurised
and air conditioning bridges. The rotating glass is hardened and
optically 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 special-design
manifold between the rings surrounding the rotating glass and the fixed
frame keeps water from entering the space between fixed and rotating glass.
This space can optionally be heated by electric resistance to avoid condensation
and formation of ice, which could prevent proper operation.
TYPE AC
Units are delivered assembled
on a hardened glass of proper shape and thickness for the window they are
to be fitted to. The window glass bears the motor that rotates the
optically rectified glass disk. On request the unit is equipped with
a heating element to prevent condensation and formation of ice. Metal
parts are turned and can be chromeplated on request.
TYPE EX
This unit is designed to be
installed in a circular hole cut in a glass, wood, acrylic or metal surface.
The unit is assembled by flange and counterring, made airtight by noeprene
gasket. The fixed hardened glass disk supports the motor which rotated
the optically rectified glass disk. On request the unit is supplied
with a heating element to prevent condensation and formation of ice.
Metal parts are turned and can be chromeplated on request.
