TECHNICAL DATA
VENTILATION UNIT WITH HEAT RECOVERY FOR COMMERCIAL AND INDUSTRIAL BUILDINGS
indoor air quality and energy saving
CRHE-H
Non-residential ventilator unit with dual flow and high
yield heat recovery. From size 1100 to 3400 it’s possible to
have also the version with enthalpic heat exchanger
PERFORMANCE
Equipped with counter current heat exchanger in alumi-
nium (Eurovent certified) and electronic backward
blade ventilators. The total bypass as standard allows
favourable climatic conditions to be taken advantage
of outside the building for free cooling (or free heating) in
automatic mode.
STRUCTURE
CRHE-H is manufactured using a profiled extruded alumi-
nium frame and 25 mm thick sandwich panels, insulated
in polyurethane foam. The panels and inner parts are
manufactured in Aluzinc, material that ensures high
strength against corrosion and oxidation. A panel with
shutter opening eases access to the filters (F7 for the
renewed air flow and G4 for the extraction air flow).
CRHE H is prepared for installation outdoors (with an
optional, specific protective roof) and indoors. Available
in 4 sizes, it can be equipped with air post-treatment
systems (inside the unit) such as: hot/cold water battery,
electrical heater or direct expansion battery. CRHE-H
was designed to enable easy configuration of the
connection to the air distribution/captation ducts. It is
also possible and easy to install post-air treatment
devices after sale.
CONTROLS
CRHE H was supplied with an electric box and control
system; it is available in a version equipped with EVO-PH
control and a version equipped with EVOD-PH-IP control
prepared for complete integration in home automation
systems (Modbus protocol with Ethernet connection or,
on request, with the addition of connection RS485). The
new version of our control systems enables extremely
easy and rapid passage from a control system to
another, even after installation with the single replace-
ment of the remote panel.
The EVO-PH control has a coloured, backlit touch screen
interface with intuitive viewing of the working status of
the machine. It enables precise adjustment of ventilator
speed and has a weekly , time schedule for automatic
management of the ventilators. It can be controlled by
an external switch to activate the booster function, it
can automatically adjust the air flow rate if connected
to an air quality probe, it can manage any air post treat-
ment accessories, it automatically manages the bypass
and prevents heat exchanger freezing by managing the
speed of the ventilators or, if installed, an electrical
pre-heating resistor (optional accessory outside the
machine); it signals to the user the need to replace the
filters (the clogging status of the filters is monitored by a
pair of different pressure switches, supplied as standard)
or an anomaly, indicating the origin. With the addition of
optional accessories (COP kit and CAV kit installed on
the channel) you can manage the ventilation machine
in constant pressure or constant flow rate mode.
The EVOD-PH-IP control has the same characteristics as
the EVO-PH version with the addition of Modbus commu-
nication protocol which allows full control of the machi-
ne by the supervision software of the home automation
system. The implemented webserver allows interaction
with the machine, even with an internet browser of a
device connected (even from remote) to the home
automation system in which the machine is inserted.
ACCESSORIES
CRHE-H can be equipped with other accessories such as:
. R.H. of probe, CO2 or CO2 / VOC
. Operating kit pressure or constant flow
. protection roof for outside installalzione
. grilles and damper
For a more complete view of the characteristics of the
control panels, please read the specific manuals
