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.
