Online CMV Selection Software
Unilab BREEZE
Online selection and quotation software for manufacturers of Controlled Mechanical Ventilation (CMV) systems.
Unilab BREEZE is the innovative online software by Unilab designed for manufacturers of Controlled Mechanical Ventilation (CMV) systems. BREEZE enables end-to-end quotation of Controlled Mechanical Ventilation systems, offering the possibility for your loyal customers and designers to use the platform.


Select the CMV Model
Once the floor plan is uploaded and the rooms are configured, you can select the appropriate Controlled Mechanical Ventilation (CMV) model. The selection is based on the required airflow and/or its price. You can also add optional accessories and include the chosen model directly in the floor plan layout.


Add Distribution Boxes, Internal and External Vents, Grilles, and Connect Everything with Ductwork
After selecting the CMV model, place all internal and external distribution boxes, vents, and grilles (with options to choose their aesthetic finish) on the floor plan. Then connect them to the unit using ductwork.
BREEZE calculates both the cost and the total length of the ductwork based on its placement in the floor plan. The software leverages established equations to calculate duct pressure losses, considering the internal diameter and length. It also accounts for the shape factor, enabling calculations for non-circular ducts (e.g., square-shaped). Additionally, it computes pressure losses for grilles and other resistive elements in the system.
Calculate & Print
Once all components are connected, click on “Calculate” to assess the system’s efficiency. You can then generate and print a detailed report that includes the parts list along with their respective prices.
ERP Integration (Optional)
On request, the software can be integrated with your ERP system for seamless management and data synchronization.
Archive Management
BREEZE also provides backend access for:
- Adding new units and associating them with components, grilles, ducts, and accessories.
- Inputting fan curves and flow regulator curves.
- Editing software translations.
This ensures full control over the database and the ability to customize and expand functionalities as needed.
