10. EVAPORATOR
PRESSURE DROPS
AND USEFUL STATIC
PRESSURES
The standard ECLs (without storage
tank and/or pump are supplied with
installed water filters as per standard:
- for ECL 020 - 025 - 030 - 040 filter
is 1"
- For ECL 050- 070 - 080 - 090 - 100
- 150 - 200 filter is 1 ¼"
NOTE
The pressure drops and the static
pressures are calculated in cooling
mode with 10°C water.
The table below states the correction
to apply to the pressure drops
on variation of the average water
temperature.
10.1. STATIC PRESSURES USEFUL
TO THE SYSTEM
For the "A, P, N, Q" versions (with
storage tank and/or pump only).
The static pressures stated here
are at net of the pressure drops of
the heat exchangers, filter, storage
tank. Therefore are to be considered
USEFUL TO SYSTEM.
NOTE
The static pressures are
calculated in cooling mode.
WITH PRESENCE OF
GLYCOL for static pressures useful
to system PLEASE CONTACT
COMPANY.
