Duraflex EcoPress Giga - Pressurisation Systems
Features
Innovative Technology and Reliability
The Duraflex EcoPress Giga offers by default an automatic,
controlled water makeup. The water make-up is controlled
in dependence on the water level in the GG primary vessel.
An even more comfortable solution: Equip the Duraflex
EcoPress Giga with the Duraflex EcoPress Vacuum
Deaerator vacuum spray tube deaeration. It does not only
free the make-up water from dissolved gases, but also
ensures that the content water in the system is almost gasfree.
“Air problems“ due to free gas bubbles at system high
points, at circulating pumps or control valves are a thing of
the past!
Modular Design and Customisation
• For heat generating systems up to and over 120°C.
• Heating capacities up to 250 MW and more.
• Pressures also above 40 bar.
• Expansion volumes up to 160,000 liters.
• Medium pressure maintenance in case of complicated
pressure conditions.
• Fully automated operation with individual operating
program and SPS.
• Suitable for high temperature hot water plants.
The expansion bend
ensures the pressure compensation
towards the atmosphere between
reservoir wall and diaphragm.
GH Hydraulics
The 10 design models of the GH
hydraulic system allows the hydraulic
adjustment to the most different
systems and environments.
The sounding pipe
deaeration extracts the gasses
from the tank and prevents a
de-aeration.
The high-quality butyl bladder
protects the expansion water
from direct air admission.

GS Control unit
The GS control in 6 basic models
ensures an excellent operating
comfort. All reflex controls have been
designed according to a uniform
design guide line.

The flex-connection
for the expansion line is
required for the proper
function of the level
measurement.
The pressure cell
(level measurement)
allows to determine the
reservoir level.
