TECHNICAL DATA
VENTILATION UNIT WITH HEAT RECOVERY FOR COMMERCIAL AND INDUSTRIAL BUILDINGS
indoor air quality and energy saving
UTA
Non Residential Ventilation Unit (NRVU) for high air
volume.
EQUIPPED
UTA is equipped with high efficiency counterflow heat
exchanger (Eurovent certified) and backward blades
EC fans.
STRUCTURE
The UTA is composed by three basic modules (two venti-
lation/filtration modules and a heat recovery/bypass
module) which can be easily placed and mounted (fast
mechanical and electrical connection). Each module is
made of extruded aluminium profiles and double skin
Aluzinc panels, sandwiched on injected polyurethane
foam insulation, thickness 45mm and density 42 Kg/m3.
UTA will be delivered with rectangular duct connections.
Two sizes available both equipped with automatic total
bypass: UTA 1 8.000 m³/h @ 200 Pa and UTA 2 13.300 m³/h
@ 200 Pa. Post heating device (electric or water) and
electrical pre heater device are integrated into the unit,
while post cooling/heating water coil and direct expan-
sion coil, are available as additional external module.
The filtering sections are composed by modules (with
standard dimensions) of F7 filters for the fresh air flow and
M5 filters for the extraction air flow.
CONTROLS
UTA is delivered in plug&play configuration with two
different control systems: EVO-PH and EVOD-PH-IP. The
last one, to be used in BMS systems with Modbus proto-
col, is also available with RS485 connection. UTA is confi-
gured to run in constant air volume modality: both air
flows (extraction and fresh air) are controlled. It’s possi-
ble to upgrade the unit with two constant pressure kits
(COP kits are optional). The EVO-PH control has a
colored backlit touch screen interface, it gives an intuiti-
ve operating status of the unit and it allows programming
the fan speed.
This control has a weekly time schedule for automatic
unit control, it can be controlled by an external switch to
activate the booster and it can automatically adjust the
air flow when connected to an air quality sensor.
It supports post-air treatment accessories and it advises
the user if filters needs to be replaced (the filter clogging
is monitored by a pair of differential pressure sensors) or if
there is any other fault showing where it comes from. If
the unit includes the optional COP Kit or CAV Kit (instal-
led in the duct) you can program the heat recovery unit
either as constant pressure or as constant flow.
The EVOD-PH-IP control has the same characteristics of
the EVO-PH version with the addition of the Modbus
communication protocol and it allows full control of the
unit by the Home Automation software system. If the unit
is in a Home Automation network, the webserver lets the
user interact with it throughout a device connected to
an Internet browser.
ACCESSORIES
UTA can be equipped with other accessories such as:
. recycling module
. silencer module
. pre-filters and pocket filters
. R.H. of probe, CO2 or CO2 / VOC
. constant pressure operation kit
. protection roof for outside instalalzione
. grilles and damper
For a more complete view of the characteristics of the
control panels, please read the specific manuals.
