TECHNICAL DATA

VENTILATION UNIT WITH HEAT RECOVERY FOR COMMERCIAL AND INDUSTRIAL BUILDINGS

indoor air quality and energy saving

CRHE-V

Non-residential ventilator unit with dual flow and high

yield heat recovery. All sizes are available also in the

version with enthalpy 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-V is manufactured using a profiled extruded alumi-

nium frame and 36 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-V is prepared for installation outdoors (with an

optional, specific protective roof) and indoors; it is

supplied with 100 mm high aluminium bases for installa-

tion on the floor. Available in 6 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-V was designed to enable easy

configuration of the connection to the air distribu-

tion/captation ducts. It is also possible and easy to install

post-air treatment devices after sale.

CONTROLLI

CRHE-V 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-

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.

CRHE-V can be equipped with other accessories such as:
