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.
