Advanced solutions for AHU
Programmable controllers for air handling units

Advanced solutions for AHU
Dixell presents a solution for the complete management of air handling units which includes programmable controllers,
LCD graphic and touch screen terminals, accessories and sensors. A dedicated and easily conﬁgurable application allows tohandle regulations dedicated to thermos-hygrometric conditions, ventilation, ﬁltration, air control and quality.
This solution can boast high ﬂexibility in the composition of the unit, multiple solutions for the available actuators and theoptional functionalities dedicated to energy saving, planning and plant management.
The AHU application has been developed in particular for OEMs and plant’s System Integrators, ensuring a high-performing
hardware and a conﬁgurable and easy-to-use application software.

Optimized management of the unit
The high connectivity and simpliﬁed conﬁgurability allow an efﬁcient, quick and intuitive management of the unit even byremote. The application is based on function blocks and is customizable in an easy and fast way.

Web site
The website in the iPro controllers ischaracterized by an intuitive interactive
graphical interface and allows you toquickly configure the unit via wizard oncommon browsers present on the market.
The remote access allows supervising andcontrol actions of the unit providing to theservice an important tool of assistance incase of any necessary maintenance action.

Applications

Below some examples of units manageable with iPro controllers.
The probes are identiﬁed as:
T Temperature

P Pressure

H Humidity

Q Air quality

S SpeedFresh air only unit
For fresh air only units, the IPG208D controller allows the management of heating andcooling resources, of the external air damper and the modulating supply ﬂow ventilation.
The solution ensures an optimal management of single-flow units and of set-pointtemperature control.

Double flow unit (supply and return)For double ﬂow AHU units with supply and return, the IPG215D controller allows themanagement of the heating, cooling, post-heating and steam humidiﬁcation resources. The
supply and return fans can be modulated, for example, depending on a constant pressurecontrol.
The solution guarantees the optimal management of the mixing chamber with returndampers, expulsion and fresh air (with minimum fresh air regulation, air quality control,
free-cooling or free-heating also in enthalpy mode).

Dixell’s solution

most of the AHUs’ applications

Double flow supply and return unit heat exchanger
For units with heat exchanger and double supply and return ﬂow, Dixell’s proposal
includes the use of the IPG215D controller combined with an IPX206D expansion module.
The solution allows to optimally manage the water heating coil, the direct expansioncooling coil, the steam humidiﬁcation, the post-heating coil with electrical heaters andthe supply and return modulating ventilation for example depending on a constant air
ﬂow control.

Complex AHU units
For very complex units which require the use of a large number of I/O, the solution
can consist of the IPG215D controller combined with one or more expansion modules(IPX206D or IPX215D).
This type of AHU unit, combined with Dixell’s solution, features a high level of ﬂexibility
that allows its use in multiple applications covering the most demanding markets as thepharmaceutical, foods and process ones.
