Impelair AS was established to serve the Heating,
Ventilation and Air Conditioning (HVAC) market
with innovative design, superior quality, advanced
logistics and reliable services. Impelair AS aims
to offer energy-efficient, easy-to-operate and
service-free HVAC equipment for the market
while maintaining premium quality.
Impelair AS is located in the Aegean Free Zone
in Izmir, Turkey. The Free Zone has more than
240 global companies taking advantage of the
simplified customs and logistics procedures.
The manufacturing processes involve high-tech
CNC machines to ensure precise manufacturing
quality and production plant efficiency.
The equipment is manufactured on assembly
and sub-assembly lines where quality control
is carried out in line with both national and
international standards. Every single unit
manufactured is checked with electrical control
equipment before packing to prevent any
problems in the field.
The HVAC market has been growing as an industry
for the last 15 years. With the enhancement
in building material technology and the new
regulations for energy efficiency imposed by the
authorities, the equipment technology is also
changing to meet demand. At Impelair AS, we
not only focus on today’s technologies but also
on communicating our vision of what tomorrow’s
needs will be.
We are working in cooperation with the major
component manufacturers, meaning we all
benefit from the mutual innovations and knowhow. By applying the results of this work to our
product range at Impelair AS, we create energyefficient products for buildings with a low energy
profile.
Renovent Units
Renovent units are designed to meet the fresh air demand for shops, offices, hotels, day care centers,
schools and similar premises. With the heat recovery exchanger, thermal efficiency of the unit exceeds
65% and with the perfectly engineered Radical blade AC fans Specific Fan Power of the unit goes as low as
0,80 kW/m-3/s-1 (EN 13779). With the standard remote LCD control panel and IQ Control the user is flexible with
several control settings like 3 speed fans and unbalanced ventilation, weekly timer, filter monitoring and by-pass
ventilation. More control settings are available with optional accessories. Class 0 flame retardant insulation is
used for sound and thermal insulation of the unit.
Functions
Renovent Units;
•Supply fresh air for indoors.
•Exhaust stale indoor air.
•Transfer heat from or to supply air from the exhaust air stream.
•Filter supply air.
Energy Savings and Responsibility for Nature
Renovent Units;
•Reduces up to 65% of the energy required to condition fresh air to ambient temperature.
•With high efficient Radical blade AC fans, reduces power consumption.
•Reduces the cooling load, as a result of the humidity heat transfer from fresh air to exhaust air stream and
decreases installed and operational capacity of the air conditioning devices.
•Reduces CO2 emission, as the result of energy saving, and prevents environmental pollution.
•Reduces initial investment cost and operational costs of air-conditioning systems, as a result of exhausted
airs heat recovery.
Advantages
•High Thermal Efficiency with patented heat exchanger design.
•Low Power Consumption with RadiCal Blade AC Fans.
•Low Sound Level with Engineered Unit Design.
•Standard LCD Remote Control with IQ Control.
•Easy Service and Maintenance with Engineered Unit Design.
Models
Renovent units are designed in 5 different types with nominal airflows varying between 500 m3/h and 2000 m3/h.

Unit Specifications
Control
Complete Package
Renovent units are equipped
with IQ Control. IQ Control is
capable of controlling AC fans,
by-pass clamp, frost heater and
operation timer. The control of
fans can be done with 3 speed
settings/unbalanced
ventilation/ventilation on demand. 2
permanent temperature sensors measure return air/fresh
air temperatures and control
the bypass. Filters are checked with timer and the user is
informed for filter maintenance
periodically.
Renovent units have by-pass ventilation as standard. With bypass ventilation it is possible to use fresh air directly to cool down
indoors at summer. The controller checks both indoor and outdoor
air temperatures and user set temperature and switches on/off the
clamp integrated directly to the unit.
ERP Compliant Fans
Renovent units are equipped
with innovative plug type
Radical blade AC fans. Fan
blades are high aerodynamic
efficient
backward
curved
design. Renovent units perform
with lower energy consumption
and sound level as a result of
the fans used. With the new
regulations, pressure drop
in the ducting system shall
also be minimized due to low
energy consumption demand.
Backward curved plug fan
design also helps reduce the
ducting systems total pressure
drop.

Slim Design
Low Sound Level
Renovent units are designed
to meet tough installation
conditions like limited ceiling
space. Renovent units are
limited to a maximum height
of 305 mm until Renovent 1000
and 445 mm until Renovent
2000.
With the innovative RadiCal blade design and the decreased pressure
drop of both components and internal design, the sound level of the
unit is reduced along with the reduced fan speed.

Components
Heat Exchanger
Eurovent Certified Aluminum cross flow plate
heat exchangers are used in Renovent Units. Heat
exchange efficiency differs according to indoor/
outdoor air temperatures and air flow. Inspection
and maintenance to the heat exchanger is done
from the heat exchanger service cover. Thanks to
the engineered design, the heat exchanger can e
removed easily without the need of disassembly of
the unit itself.
EA Stale air exhaust
SA Fresh air supply to the room
OA Fresh air induction
RA Stale air extraction from the room
Control
Renovent units are equipped with IQ Control. IQ Control is capable of
controlling AC fans, by-pass clamp, frost heater and operation timer.
The control of fans can be done with 3 speed settings/unbalanced
ventilation/ventilation on demand. 2 permanent temperature sensors
measure return air/fresh air temperatures and control the by-pass.
Filters are checked with timer and the user is informed for filter
maintenance periodically.
By-Pass
By-pass ventilation is done during summer and allows return air to by-pass the heat exchanger introducing fresh
air at outdoor air temperature and cools down indoors. Renovent Units are equipped with by-pass ventilation
as standard. With the pre-installed temperature sensors IQ Control checks return air temperature, fresh air
temperature and user set temperature. According to the evaluation in the PCB, the by-pass clamp is opened
automatically.

Components
Fans
Renovent units are equipped with innovative
plug type Radical blade AC fans. Fan blades are
high aerodynamic efficient backward curved
design. Renovent units perform with lower energy
consumption and sound level as a result of the fans
used. With the new regulations, pressure drop in the
ducting system shall also be minimized due to low
energy consumption demand. Backward curved plug
fan design also helps reduce the ducting systems
total pressure drop.
Casing
Renovent units are designed to have a compact and service-easy construction. All of the components can be
disassembled without the need of dismantling the unit and ducts. The height of the product is minimized to
have a compact design ensuring the minimum pressure drop inside the unit at the mean time. Galvanized sheet
metal is used for Renovent units and the unit is insulated against thermal leakage and sound with M1 class
flame retardant Polyurethane foam.
Filters
Panel filters are used in Renovent units for standard
filtration. Filtration class is G3 according to EN 779.
G3 filters are medium efficiency disposable air filters
suitable for ventilation applications with good dust
holding capacity. The filters consist of a dry nonwoven extended surface fabric media and create low
initial pressure drop.

Home
Ventilation On Demand; VOD, by use of additional
CO2/IAQ or RH sensor the demand indoors
is calculated and the fan speed settings are
adjusted accordingly. To switch to VOD mode, a
proper sensor must be installed and connected,
to the duet system and also the user must select
“VOD” on Select Mode menu of the Remote
Control.
Minimum Air Flow
Minimum Air Conditioning Load

Partial
Load
When VOD (Ventilation On Demand) is selected
the fan speed is controlled by the analog 0.10V
input signal. At 0...1V the fans are running at
minimum VOD speed and at 9...10V the fans are
running at maximum speed for VOD. In between
the fan speed is linearly controlled.
