Pumps:
Energy class A, electronically-controlled, maintenance-free,
high efficiency, wet rotor circulation pumps are used with
EC motors. The pump body is made of grey cast iron with
a cataphoresis KTL finish, which is an excellent protection
against corrosion. The thermal insulation is made of
polypropylene, the shaft is made of stainless steel, the
bearings are made of metal-impregnated carbon, and the
impeller with a three-dimensional coil is made of synthetic
material with a carbon fibre hermetic insulation coating.
Solenoid valves:
Solenoid valves are widely used to control the flow of hot/
cold liquids with on/off-type utilities. The principle of
operation consists of an electrical current being applied to
a coil that creates a magnetic field. This is transformed into
mechanical energy, which opens or closes the valve. The
principle of operation is very reliable, inexpensive and widely
used for each type of application with ON/OFF utilities.
Liquid separator:
The liquid separator is placed on the compressor intake line
and has the function of containing the excess refrigerant
that has not evaporated and prevent it from returning to
the compressor in its liquid state, thereby preventing any
damage this could cause.
Liquid receiver:
The unit is modulating with variable flows and possible
operating conditions that may differ. The optimal refrigerant
charge depends on the volumes of the heat exchangers and
the points mentioned and can therefore vary significantly
in the various operating modes. The liquid receiver is
therefore important to restore equilibrium, especially during
transitions.
