Picture
Mechanical manometer type MDD80 are used
for direct visibility of pressure. They are working
by the bourdon-tube measuring system.
Those types are very robust because of special
soldering and can be used until temperatures
90/130°C without case of additional safety
equipment like siphons etc.
Those manometers can be used for many
applications in district and house heating
systems.
They are resistent to different heating
water qualities, which are in accordance with
valid qualities rules (f.e. FW510, VDI2035) or also
in DHW-systems (acc. german TWVO or similar).
District heating manometers of type MDD80
produced in accordance with norm EN837-1.
