OnePlus
Packaged Air Handling Units for Ducted
Installations
Caring for the environment!
A New Concept
System Modularity
New packaged air handling units OnePlus series are
the latest offspring of Apen Group’s experience. These
units have been designed and developed to guarantee
top installation flexibility inside or outside the buildings
where air conditioning is required.
The total heat requirement can be split across multiple
units, thereby making the installation convenient and
rational: heat output can be managed on an area
basis, and new units can be installed if additional
requirements arise.
The pulsing heart of OnePlus units is their modulating
heat generator, including a premixed burner with low
NOx output and double inlet centrifugal fans.
Available heads range from 200 to 400 Pa, thus
allowing maximum flexibility in designing highly
articulated ducted systems.
Cooling Units
Cooling coils can be installed on OnePlus units to meet
comfort requirements both in winter and summer.
Why OnePlus?
Models and Configurations
Clean Combustion
The burners installed in OnePlus units fully premix
air and gas. A regulating heat output device is also
installed. This results in:
- No emissions of carbon monoxide (CO = 0).
Ductable packaged air handling units series OnePlus
are available in two configurations:
• PLA - for indoor installation

- Very low emission of nitrogen oxides, below 30 parts
per million (NOx < 30 ppm).
- Low emission of carbon dioxide, thanks to
high combustion efficiency and reduction of fuel
consumption due to heat output modulation.
Fuel Savings up to 30%

High combustion efficiency, up to 94 % (on net
calorific value), continuous modulation of heat output,
and minimized stratification of warm air allow fuel
savings up to 30%, in comparison to traditional “ONOFF” heating systems.
Flexibility in Installation
EASE OF INSTALLATION
CARTIGLIO cod. X07005 ed.0411
OnePlus units are highly versatile and ideal for any
kind of installation, thanks to their heads, ranging
from 200 to 400 Pa, and to the possibility of installing
mixing boxes to create free cooling and recirculation
of air.
The equipment only needs to be connected to gas
supply and wired to single-phase 230V – 50 Hz m
power supply.

Moreover, for any outdoor or indoor configuration, the
user can choose the required static pressure among the
available values: 200 Pa or 400 Pa.
Technical Features
Every part of our OnePlus air handling units has been
attentively designed and carefully tested in Apen
Group’s R&D Centre to develop and obtain a topquality, highly-reliable product.
AIR/GAS MIX: GUARANTEED SAFETY
Furnace & Heat Exchanger
If combustion air fails, the gas valve closes. If
combustion air decreases, the valve automatically
reduces gas flow while maintaining optimum
combustion parameters
Furnace and air/flue exchanger are entirely built with
mild stainless steel (low carbon content) to assures
maximum reliability and long life cycle.
The drop-shaped furnace and the air/flue exchanger,
whose tube bundle is custom designed, guarantee
performance that place OnePlus units among the
leaders for heat efficiency, with an outstanding value
of 94 %.
Heat exchanger
and combustion chamber
An advanced technique for mixing air and gas
guarantees total safety. The gas valve delivers gas
based on air flow rate, according to a ratio set by the
Manufacturer.
FAN ASSEMBLY
Depending on unit capacity, the fan assembly includes
a single or double centrifugal fan rotating at low RPM
speed, to reduce noisiness.
Double inlet fans are statically and dynamically
balanced and are belt-driven by electrical motors.
PREMIX BURNER
The burner is entirely made of AISI 430 steel and
undergoes specific engineering processing that
guarantee top reliability and high thermal-mechanical
performance.
ELECTRONIC CARD
The microprocessor-based electronic card regulates
continuous modulation of heat output and controls both
the electrical fan for air/gas mixing and the gas valve.
SAFETY AND CONTROL DEVICES
The following devices are installed in OnePlus units:
1. Safety thermostat with manual reset and positive
safety
2. Electronic ignition device for the burner and
ionisation flame control device
3. Ignition and flame detection electrodes
Accessories
Accessories
OnePlus air handling units can include, upon request,
filters, mixing boxes, dampers and conditioning units.
In addition, the following optional devices are available
to control the equipment
STANDARD REMOTE CONTROL
CHRONOTHERMOSTAT
FILTER AND MIXING BOX
Mixing box is designed in order to allow various
configurations, and it can be equipped with shutter on
all sides. It is equipped with G3 class cell filter and it
can be supplied with G4 class filter on demand.
The chronothermostat allows you to control and display
working phases and possible failures. It also allows
changing setup parameters using the electronic card
installed in the unit.
These are the available functions of the card:
• Timer
• Room Thermostat
• Control Panel
• Remote Lock and Unlock Signals
• Check Control of Working Parameters

KONDENSA.NET software
For his own OnePlus heaters, Apen Group has developed a program for
management named Kondensa.net with the objective to permit an
easy check of working on, of records of
temperatures, of the remote maintenance of the
appliances and of the consumptions, eliminating
any chronothermostats, remote controls or
programming clocks.
It is sufficient to cable the modulating card, with
only two cables, to a computer, at distances up to
1100 meters without need of signal amplifier.
In the configuration phase, it is possible to divide in
groups/areas (building or departments), the heaters
that the user wants to manage at different timing and
temperatures.
Once the configuration is made, the user disposes of
a control panel with a great deal of information.
For each defined area, it is possible to monitor the
working modes of each heater, represented by
different icons.

FIG. 1
For each group, making double click on the clock of
the group, it is possible to manage and visualize the
working calendar with the different setting:
• installation OFF
• heating ON
• ventilation ON
• antifreeze function ON
FIG. 2
For each day of the week (fig.2) it is possible to set the
ON-hour and the OFF-hour, eventual intervals and the
desired room temperature.
FIG. 3
Besides clicking twice on the single heater, it is possible to
visualize the details, of the state of functioning.

If it is in failure, it is also possible to visualize the kind of
working anomaly and to reset the heater in order to let it start
again.
The managing program Kondensa.net has been developed
with three safety levels, with access through password:
Operator, Technical and Service.
Each level is habilitated for defined activities or simply
visualisations.
This contributes to assure the highest protection of the
managing system.
