The engineer must prepare the other accessories for completion
of the hydraulic circuit: thermal buffer tank, air bleeder valve (in
models 90 to 180), regulation, cut-off and draining valves, thermal
pressure gauges, etc.
• LPC/ILPC version with hydraulic module
In addition to the previously described motorised pump group, these
units include a module with a thermal insulation tank made of black
stainless steel, painted and thermally insulated, with an electric
tank heater.
The module can be supplied:
- Coupled to the LPC / ILPC unit, models 90 to 360 (STD version)
and models 90 to 280 (HEE version).
- Separate for connection on site by the installer. The diameters
of the hydraulic connections between unit and module can be
referred to in the next table:
• LPC/ILPC version (circulation pump included)
These units include a motorised pump group made up of: centrifugal
circulation pump, closed expansion vessel, safety valve with a tare
value of 4 bar, draining valve, and automatic air bleeder valve (from
model 200V-STD and 160V-HEE).
A kit with a stainless steel mesh fi lter (500 microns) is also supplied
for installation by the installer. It is also necessary to install this
fi lter in the hydraulic power supply to the unit in order to prevent
clogging of the plate exchanger.
Note: in this case is posible to supply in the kit fl exible hydraulic
connections of 500 mm (for more detail, please refer to the “separate
hydraulic module” of chapter 10.
The following graph represents the pressure drop for that fi lter:
