12.2 - Description
12.2.1 -
Hydraulic module without variable speed
(Options 116R, 116S, 116T, 116U)
The hydraulic module is composed of the system's main hydraulic
components: factory-fitted water pump, screen filter and relief
valve.
The fixed-speed operating pressure pump provides the nominal
flow rate for the system water loop.
Several types of water pump are available to suit all applications:
-Single or dual low pressure pumps
-Single or dual high pressure pumps.
The nominal flow rate of the system should be adjusted using a
manual control valve provided by the customer.
The relief valve placed on the water inlet pipes at the pump inlet
limits the pressure to 400 kPa (4 bar).
A screen filter that can be easily removed is placed at the pump
inlet and protects the pump and the plate heat exchanger against
solid particles that are greater than 1.2 mm.
Additional options can be ordered if necessary:
-
Option 42A (42B if option 307): hydraulic module protection
(42A) or hydraulic module and buffer tank protection (42B)
down to an outdoor temperature of -20 °C.
-Option 293: Expansion tank for water circulation system.
IMPORTANT: The use of the hydraulic module on open
systems is prohibited.
12.2.2 -
Hydraulic module with variable speed
(Options 116V, 116W)
The composition of the hydraulic module with variable speed is
similar to that of the hydraulic module without variable speed.
In this case, the pump is controlled by a variable frequency drive
that allows the pump's nominal flow rate to be adjusted according
to the chosen control mode (constant pressure or temperature
differential, or fixed speed) and the installation operating
conditions.
IMPORTANT: The use of the hydraulic module on open systems
is prohibited.
