Operation sequences
A. Water enters from the water supply (1) and arrives to the dispersion
manifold (4). The water flow is adjusted with a manual gate valve (3).
B. The calibrated orifices deliver uniformly the water over each
media pad (5).
C. Dry air passes through a corrugated bank of wetted cells
media (5). Air is cooled and humidified.
D. The irrigation piping draining (6) should be installed in order to
avoid any microbiological issues.
E. The excess water washes the EvaPack
™ evaporative pad and
is eliminated (with minerals) from the water basin (2) through the
draining connection (7).
This configuration is recommended with high hardness supplied
water (to increase the pad life time) or with reverse osmosis water
(to reduce the RO water consumption).
F. Water level switch option (8) could be installed as an alarm system.

EvaPack™ humidifier, operation principle
Armstrong EvaPack™ Series converts ordinary tap water into
water vapor by using an adiabatic process. Dry air passes
through a corrugated bank of wetted cells media made from
non-organic fibers. EvaPack™ series uses the sensible air heat
to evaporate the water. The air is cooled and humidified.
All types of water can be used (see page 8 for more details
on water quality).
