Filter fouling is measured by a pressure sensor located in the electrics box.
It is set to 1.5 times the value for the filter when clean (pressure ports upstream and downstream of the filter).
11.1.5 - Standard control elements:
(factory-wired)
-
Intake temperature sensor.
-
Differential pressure sensor: attached to the electrics box, this allows the difference in pressure upstream and downstream of
the filter to be measured, so as to determine whether the filter is fouled.
-
Water leak sensor: found at the end of a wound cable located at the bottom of the vertical unit so that it is long enough to extend
downwards into a raised floor, if required, and to be positioned in the area to be monitored.
It can be added on request.
11.2 - Optional components
11.2.1 - Heating coil
Moderately tighten the "coil supply" connections to avoid damaging the manifolds.
The coil is adjusted by a two-way or four-way valve equipped with a 0-10V servomotor (mounted and connected).
