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.
