INSTALLATION AND COMMISSIONING MANUAL
Function
The CALEFFI GEO
®
110 series manifolds are used for the
control and distribution of medium in closed circuit
geothermal plants.
In circuits with geothermal heat pump the thermal medium
is generally a mixture of water and anti-freeze fluid since
the temperatures can be extremely low. The components
are made with high-performance materials for this type of
application.
They are supplied pre-assembled, complete with end
fittings and temperature gauges, or in ready-to-assemble
modules.
