UNILAB SMART-AIR is a software aimed at generating offers of Air Handling Units. The software has a modular structure:
SELECTION Module, available in 2 editions, STANDARD (no recuperators) and PROFESSIONAL (with recuperators): the software selects the correct size according to the air flow and face velocity, selects the components (coils, filters, fans, etc.), provides the gross price, dimensions and weight, and produces a commercial offer in a few minutes; 
OUT OF RANGE Module: allows the creation of offers of units out of the standard range and catalogue, inserting the coils’ and unit’s frontal dimensions which are defined at that moment.

Both solutions allow 3 simultaneous users & include an ARCHIVE MANAGEMENT, enabling the user to manage, add, delete & modify all main data from the database, with a user-friendly interface.


  • VIEW 3: produces a schematic drawing in 3D for the Production Department, provides the documentation (DWG, DXF, STL, STEP formats etc., a cut list of tamponages, profiles and panels) necessary to build the units. The software provides technical drawings of profiles, omega, panels, blankings and the basement according to the real conditions. The program considers drawings related to the elements of the sections such as sketches.
  • Rendering 3D units: This module allows you to add to the printout the 3D representation of the Air Handling Unit.
  • 2D option: This module allows you to add to the printout the 2D representation of the Air Handling Unit, and also to export it in compatible AutoCad formats, modify it and reimport your custom drawing!


UNILAB SMART-AIR, the advanced software that satisfies the requirements of both Sales and Production Departments, a smart solution for HVAC companies manufacturing or selling Air Handling Units. The software drastically reduces the time from acquiring the order to its manufacturing. Its user-friendly interface allows a quick selection of standard units, previously uploaded in the database.
Once the offer has been created, the software provides several outputs that help the Technical Department design the unit, which will then be sent to the Production Department, and then to the numerical control machines (CNC). The soft-ware helps the technical department perform about the 80% of its work! Only the remaining 20%, which is the revision of the drawings generated by the program, is in charge of the designers.

SMART-AIR is the tool that UNILAB recommends for HVAC companies which need to design or rate Air Handling Units.

Why would you prefer Unilab’s SMART-AIR?

Firstly, because SMART-AIR software is very handy, thanks to its autonomous management, through a series of fast-moving steps, allowing selection completion to be achieved. This software can be used both as a technical design tool to build a new unit or as a commercial tool to give to agents who need to provide multiple quotations in a short space of time. It enables users to input fan and compressor data quickly and easily.

Design Air Handling Units with focus on total cost

By using our SMART-AIR you can monitor all variables relating to costs: you can calculate the cost, price and weight of an air handling unit accurately. Thanks to SMART-AIR it’s also possible to estimate the labour cost.


VIEW3 is the right solution for companies wishing to improve the efficiency of their Project Dept.: in two steps the user can create an air handling unit and evaluate whether the unit fully satisfies their requirements. This application is very simple and intuitive: it allows the creation of the scheme of the unit, the calculation and selection of all necessary components and, if required, a 3D view of the unit.
