Flexible ventilation solutions with emphasis on performance, efficiency and variability
The DUOVENT air handling units are a modern solution for comfortable and energy efficient ventilation of commercial and industrial spaces. They offer a wide range of configuration options that allow the unit to be precisely tailored to the requirements of a specific project.

The COMPACT range - a compact solution without compromise
The COMPACT series is designed for applications where the emphasis is on space saving, easy installation and high efficiency.
Units are available in the following variants:
- COMPACT DV - with counterflow plate heat exchanger
- COMPACT RV - with rotary regenerative heat exchanger
Depending on the layout, the following can be selected:
- standard design - basic horizontal throat design with the possibility of selecting dozens of other throat design options in the VentiCAD design software
- TOP version - throats in basic design vertically with the possibility of selecting dozens of other variants in the design software VentiCAD

Wide range of equipment and design options
DUOVENT units allow the integration of:
- cooling
- heating
- mixing
- exchanger bypass
Units can also be supplied with Digireg ®, which ensures reliable operation control.
Digireg ® control allows the units to operate in three basic modes:
- COP (Constant Over Pressure operation)
- VAV (Variable Air Volume - variable air volume operation based on external inputs)
- CAV (Constant Air Volume - constant air volume operation regardless of the line pressure)
The result is a solution optimized for the specific requirements of your project.
Indoor and outdoor design
All variants of DUOVENT units can also be supplied:
- outdoor with modifications for harsh climatic conditions
- in the pool version with special modifications for pool hall ventilation
- in kitchen version with special modifications for ventilation of commercial kitchens
Customised solutions
In addition to the standard ranges, we also offer:
- custom fabrication of assembled units
- airflows in the tens of thousands of m³/h
- individual design solutions
Choose the ideal DUOVENT air handling unit for your project. Whether you are dealing with office spaces, shops, schools, apartment buildings or industrial applications, DUOVENT air handling units offer the right solution.
