The strongest ventilation program on the market

Design your ventilation system the way you want

With capacities from 1,050 to 36,000 m³/h, you'll always find a solution that fits your needs

The many modules in the VEX4000 series each have their own function, but are adapted to each other. This means that you can put together your ventilation unit exactly according to your needs and wishes, while your finished unit has the same width and height throughout. You can also choose whether you want your unit to be LEFT or RIGHT.

The many modules and their functions

Unique project planning with

Whatever your project, VEX4000 is up to the task, and with our design program EXselectPRO you can combine and assemble your ventilation system the way you want. At the same time, the program provides you with detailed technical data, dimensional sketches and energy calculations and labels. Easy and straightforward!

Installation has never been easier

1. Unit delivered assembled
   If the unit is delivered assembled, EXHAUSTO ensures that all modules are correctly connected to each other and assembled on a base frame.
2. Modules delivered separately
   In many cases it can be an advantage to receive the modules individually, for example if the modules have to pass through doors or up stairs. That's why VEX4000 is designed in a way that makes it very easy to assemble.
3. SPLIT solution
   The unit is delivered disassembled in so-called "Flat-Pack" so that even large units can be transported into narrow access areas.

EXHAUSTO ALC™

The patented solution to prevent the spread of disease through a rotary exchanger ventilation unit

ALC™ is a simple plug & play solution offered for VEX4000 with rotary exchanger. The solution prevents leakage and thus prevents the spread of viruses, particles and gases through the ventilation system. By activating ALC^CTM, leakage is prevented by the VEX's automatic system, regardless of the current operating situation.

How ALC™ works

1. A sensor measures the pressure difference between the exhaust and supply air chambers in the VEX unit.
2. The automation in the unit regulates an exhaust air damper based on the pressure difference.
3. This ensures that the pressure in the exhaust air chamber is always lower than in the supply air

With the automatic leakage control, the Exhaust Air Transfer Ratio (EATR) is reduced to 0%** and recirculation of airborne particles and gases, including virus particles, is eliminated. At the same time, ALC™ is an energy-efficient solution as demand-controlled operation can be done without leakage problems.

Benefits:

• A simple plug & play solution that can also be retrofitted
• Exhaust air transfer rate EATR = 0%**
• The perfect solution for hotels, educational institutions, offices, hospitals, shopping centers etc

**Tested and validated at Danish Technical University. EATR = 0% based on Eurovent "Air Leakages in Air Handling Units: Guidelines for Improving Indoor Air Quality and Correcting Performance", 2021, EN308 and EN16798-3

Heat pump in combination with ventilation

Energy efficiency and low energy consumption requirements for ventilation solutions have increased the focus on combining heat recovery with an integrated heat pump. By combining ventilation, heating and cooling in one unit, you get a solution that is both highly energy efficient and far simpler than traditional cooling solutions with chillers and ducting on the roof.

With VEX4000RHP you get...

• Heating, cooling and ventilation in one integrated unit
• One factory-tested unit
• Advanced EXcon automation
• No need for additional heating/cooling installations
• Fast, simple calculation, documentation and technical data via EXselectPRO
• One supplier for the whole solution

With a VEX4000RHP-ER, a rotary heat exchanger is placed between the evaporator and condenser for the lowest energy consumption and refrigeration recovery. With VEX4000RHP, the heat exchanger and heat pump are placed in separate modules, contributing to a compact solution that is easier to transport.

We assume here that the heat pump or the heat exchanger must run half of the year at 33% capacity to achieve the supply air temperature. Compared to an electrical heating coil VEX4000 RHP and VEX4000 ER-RHP reduces the heat consumption by 60%/82% respectively.

Any extra investment when purchasing a heat pump pays for itself relatively quickly. Comparison with district heating, gas, oil or other energy source will depend on price per kW.

43% energyEnergy savings vs. VAV
World-class energy efficiency with patented adaptive pressure control

The VEX4000 unit comes with EXcon automation, which allows you to use EXHAUSTO's patented adaptive pressure control (aDCV). Adaptive pressure control continuously optimizes the pressure in the unit depending on the demand in the building, reducing energy consumption compared to traditional methods of pressure control (CAV, VAV, and DCV). Through the patented adaptive pressure control, up to 43%* savings on energy costs can be achieved.

*Up to 43% compared to a system with constant pressure control (VAV). Up to 20% compared to a demand-controlled system with constant pressure control (DCV)

Operate the system when you want, where you want

Setting and control via web server from PC, smartphone or tablet. Network communication supports BacNet over TCP/IP and Modbus over RS485 or TCP/IP. Communication with LonWorks can also be supported as an option.
